To generate EABI compliant code specify --abi=eabi. cmdline --abs_directory -fb STRING required dir Absolute listing directory (default is .obj dir) Absolute listing directory (default is .obj dir) cmdline --absolute_listing -aa Generate absolute listing file Generate absolute listing file simple --advice:performance ONEOF optional all,none all none all Provide advice on optimization techniques Provide advice on optimization techniques to ensure use of right options and improve software pipelining. simple --advice:performance_dir STRING required opt Place advice file in specified directory Place advice file in specified directory simple --advice:performance_file STRING optional opt Place advice in specified file Place advice in specified file simple --aliased_variables -ma Assume called funcs create hidden aliases (rare) Assume called funcs create hidden aliases (rare) simple --analyze ONEOF required codecov,callgraph codecov callgraph Generate analysis info from profile data Generate analysis information about code coverage or call graph information in the form of CSV files. This information can then be read and interpreted by other tools. For example, the cache layout tool, clt6x, can be used to interpret the call graph information and produce a preferred function order that can be incorporated into the application link. The compiler can only generate one kind of analysis information for a given invocation of the compiler. GEN_PROFILE_INFO simple --analyze_only Only generate analysis Generate analysis only; do not continue compilation. This option is used in combination with the --analyze option to instruct the compiler to halt the compilation after it has completed the generation of analysis information requested in the --analyze option.

Disable code-size optimization that calls RTS functions _push_rts() and _pop_rts(). simple --disable_software_pipeline -mu Disable software pipelining Disable software pipelining simple --display_error_number -pden Emit diagnostic identifier numbers Emit the diagnostic identifier numbers along with diagnostic messages. These identifiers can be used with options such as -pds to suppress a specific diagnostic. simple --dprel Always use DP-relative addressing for data (ELF only) Always use DP-relative addressing for data (ELF only) simple --dsbt Generate addressing via Dynamic Segment Base Table This option causes the compiler to load the DP from the Data Segment Address Table (DBST) for every function marked exported. This allows each dynamic object to have its own near DP segment and allows efficient near DP addressing in each dynamic module. simple --embedded_cpp -pe Embedded C++ Enable support for embedded C++ KR_COMPATIBLE simple --emit_warnings_as_errors -pdew Treat warnings as errors Treat warnings as errors NO_WARNINGS simple --entry_hook STRING optional hook_function_name __entry_hook Insert this call at entry to each function Insert this call at entry to each function simple --entry_parm ONEOF required name,address,none name address none Pass caller's name or address to entry hook Pass caller's name or address to entry hook simple --exceptions Enable C++ exception handling Enable C++ exception handling RTTI --rtti DISABLE_CUSTOM_CALL_CONV --disable_custom_call_conv simple --exit_hook STRING optional hook_function_name __exit_hook Insert this call at exit from each function Insert this call at exit from each function simple --exit_parm ONEOF required name,address,none name address none Pass caller's name or address to exit hook Pass caller's name or address to exit hook simple --export_all_cpp_vtbl Export C++ virtual tables by default If a c++ class is not exported, its virtual table and typeinfo are not exported. This option exports these symbols for all classes. simple --extern_c_can_throw Allow extern C functions to propagate exceptions This option is only supported under EABI for table-driven exception handling (TDEH). This option is valid only when `--exceptions` is also present. This option allows a function defined in C++ with extern `C` linkage to propagate exceptions. simple --float_operations_allowed ONEOF required all,32,64,none all 32 64 none Floating point precision accepted by compiler Control the acceptable precision of floating point operations. The default is all. simple --fp_mode ONEOF required relaxed,strict relaxed strict strict Floating Point mode Specify a floating point mode. In relaxed mode if the result of a double-precision floating point expression is assigned to a single-precision floating-point or an integer, the computations in the expression are converted to single-precision computations. Any double-precision constants in the expression are also converted to single-precision if they will fit. Floating point arithmetic reassociation is also allowed. This behavior is not ISO conformant, but results in faster/smaller code, with some loss in accuracy. simple --fp_not_associative -mc Do not reorder floating point operations Do not reorder floating point operations FP_REASSOC --fp_reassoc=off simple --fp_reassoc ONEOF required on,off on off on Allow reassociation of FP arithmetic Set to on to allow reassociation of floating point arithmetic even in cases where the reassociation will result in a slightly different answer. simple --gcc Enable support for GCC extensions This option enables the support for GCC extensions. This feature is incompatible with strict ANSI mode. RELAXED_ANSI --relaxed_ansi STRICT_ANSI simple --gen_acp_raw -pl Output raw listing to .rl file Output raw listing to .rl file simple --gen_acp_xref -px Output xref listing to .crl file Output xref listing to .crl file simple --gen_func_subsections -mo ONEOF optional on,off on off on Place each function in a separate subsection Place each function in a separate subsection USE_DEAD_FUNCS_LIST simple --gen_opt_info -on RANGE required 0-2 Generate optimizer information file at level [0-2] Set the optimizer information file level, or disable with 0. Level 1 includes basic information. Level 2 includes detailed information. The file will be created in the assembly directory if a custom asm directory is specified on the command line otherwise it will be created in the object file directory. simple --gen_profile_info Generate profile feedback data Instrument the object code that is generated for a compilation with path profiling information. The compiler will annotate the code that is generated for an application so that, when executed, the application can generate information about which code paths were executed and how often. This profile data can then be used by subsequent compiles to analyze code coverage or call graph information to assist with subsequent development. ANALYZE USE_PROFILE_INFO cmdline --help -h Show help screen Show usage information. When followed by another option or a phrase display that option's detailed information, or search for options related to that phrase. simple --import_helper_functions Treat compiler helper functions as imported refs This option tells the compiler to treat calls to compiler helper functions as imported references. Compiler helper functions are part of the runtime support library. This option is useful in platforms that support dynamic shared objects (DSO/DLL) where the OS can provide runtime support in a shared object. Without this option, the compiler treats helper function calls as non-imported references and the supporting runtime functions are statically linked in by the static linker. simple --import_undef ONEOF optional on,off on off on Import all undefined symbols This option imports all undefined symbols. simple --include_file -ahi STRINGLIST required filename Simulate source '.include filename' Simulate source '.include filename' simple --include_path -I STRINGLIST required dir Add dir to #include search path Add the specified dir(ectory) to the #include file search path list. simple --inline_plt ONEOF optional on,off on off on Inline the import function call stub. The linker generates an import function call stub to call an imported function. This linker generated call stub is called 'Procedure Linkage Table' (PLT) entry. The PLT entry is similar to a trampoline. The performance of the generated code can be improved if the PLT entry is inlined. This option makes the compiler inline the PLT. Note that the use of this option can increase the code size in some cases. Also the dynamic load time can increase as the dynamic linker needs to patch more entries simple --interrupt_threshold -mi NUMBER optional # Specify maximum disabled interrupt cycles Specify the maximum number of cycles that interrupts may be disabled. simple --issue_remarks -pdr Issue remarks Issue remarks, which are normally suppressed. simple --keep_asm -k Keep the generated assembly language (.asm) file Keep the generated assembly language (.asm) file simple --keep_unneeded_statics Do not delete unreferenced static variables The parser, by default, will remark about and then remove any unreferenced static variables. This option will keep the parser from deleting unreferenced static variables and any static functions that are, in turn referenced by these variables. simple --kr_compatible -pk K & R compatibility Enable K & R C compatibility. EMBEDDED_CPP simple --linux Generate code for Linux Set all the necessary options to build code for Linux. ABI --abi=eabi DSBT --dsbt GEN_PIC --gen_pic STATIC_TLS --static_tls=off simple --list_directory -ff STRING required dir Listing/xref file directory (default is .obj dir) Listing/xref file directory (default is .obj dir) ASM_LISTING --asm_listing simple --listing_extension -es STRING required .ext Extension for listing files (default is .lst) Extension for listing files (default is .lst) simple --machine_regs Display reg operands as machine registers in asm When compiling linear assembly, register operands can be displayed in the assembly file as either machine registers or symbolic registers. Symbolic registers is the default. Use this option to display machine registers in the assembly file when compiling linear assembly. When compiling C/C++ machine registers are the default. simple --mem_model:const ONEOF required data,far,far_aggregates data far far_aggregates data Const access model Const access model simple --mem_model:data ONEOF required near,far,far_aggregates near far far_aggregates far_aggregates Data access model Data access model simple --misra_advisory ONEOF required error,warning,remark,suppress error warning remark suppress Set severity of MISRA 'advisory' rule class Set diagnostic severity level for the MISRA advisory class of rules. See the --check_misra option for further information. simple --misra_required ONEOF required error,warning,remark,suppress error warning remark suppress Set severity of MISRA 'required' rule class Set the diagnostic severity level for the MISRA required class of rules. See the --check_misra option for further information. simple --multibyte_chars -pc Multibyte character support Enable parser support for multibyte character sequences in comments, string literals, and character constants. simple --multithread Multi-threading is assumed Indicate that application uses multi-threading or prefers to be linked with a thread-safe version of the RTS library USE_LIBC_TLS --use_libc_tls simple --no_bad_aliases -mt Assume no irregular alias or loop behavior Assume no irregular alias or loop behavior simple --no_compress Disable compression for 6400+ This option disables compression (use of 16-bit instructions) for 6400+. It also tells the assembler to (1) prevent labeled execute packets from spanning fetch packet boundaries, (2) pad the end of code sections to 32-byte boundaries, and (3) handle .align directives. Normally for 6400+, these are the responsibilities of the compressor (cmp6x). simple --no_const_clink Do not generate .clink for .const sections Do not generate .clink directives for const global arrays. By default these arrays are placed in a .const subsection and conditionally linked. simple --no_inlining -pi Ignore inline keyword Ignore the inline keyword while parsing. simple --no_intrinsics -pn Disable intrinsic functions Disable intrinsic functions in the parser. simple --no_reload_errors Prevent loop buffer reload-related error detection Prevent detection of loop buffer reload-related errors.

This option will enable EDG parser to provide a mechanism for, in effect, taking a snapshot of the state of the compilation at a particular point and writing it to a disk file before completing the parsing; then, when recompiling the same source file or compiling another file with the same set of header files, it can recognize the `snapshot point`, and reload this file instead of recompile these headers. In this way, compilation time can be reduced. simple --pch_dir STRING required dir Specify precompiled header path Specify path where precompiled header file will reside. This option will direct the parser to put the generated precompiled header file in the specified directory. If this option is not used, the precompiled header file will be put into the same directory as the primary source file simple --pch_verbose Info on considered & unused precompiled headers This option displays a message for each precompiled header file that is considered but can not be used. It also gives the reason why it can not be used. simple --pic ONEOF optional near,far near far near Position-independent addressing for a shared object Generate position-independent addressing for a dynamic shared object. All externally visible objects will be addressed through a Global Offset Table (GOT). DSBT --dsbt cmdline --pp_directory STRING required dir Preprocessor file directory (default is .) Place preprocessor output files in specified directory. The directory must exist prior to compiler invocation. simple --preinclude STRINGLIST required filename Specify a preinclude file Include the source code of the indicated file at the beginning of the compilation.

PREPROC_DEPENDENCY PREPROC_INCLUDES PREPROC_MACROS cmdline --preproc_with_compile -ppa Continue compilation after using -pp<X> options. This option instructs the compiler to additionally continue compilation of the source file (rather than exiting) after generating a pre-processing .pp output file such as those generated by -ppd (dependencies) -ppi (included files), or -ppm (macros). cmdline --preproc_with_line -ppl Preprocess only; maintain line directives Only preprocess the source file(s) and then stop; maintain #line directives in the output.. PREPROC_MACROS PREPROC_INCLUDES PREPROC_DEPENDENCY simple --printf_support ONEOF required nofloat,minimal,full nofloat minimal full Level of printf support required Printf/sprintf functions use a common low level routine, _printfi which processes a given printf format string. The full version of _printfi provides formatting capabilities that are not required in typical embedded applications. To address this the C runtime library also includes two limited of versions of _printfi that provide a useful subset of the formatting features specified by C library standard. One version excludes support for printing floating values. All format specifiers except for %f, %g, %G, %e, or %E are supported. To specify this version use the option '--printf_support=nofloat' when linking. The other version only supports printing of integer, char, or string values without width or precision flags. Only %%, %d, %o, %c, %s and %x are supported. To specify this version use the option '--printf_support=minimal' when linking. simple --profile:breakpt Compile for breakpoint-based profiling Disable optimizations that cannot be handled by a breakpoint-based profiler SYMDEBUG__NONE simple --profile:power Compile for power profiling Enable power profiling support by inserting NOPs into the frame code. These NOPs can then be instrumented by the power profiling tooling to track power usage of functions. If the power profiling tool is not used, this option will increase the cycle count of each function because of the NOPs. This switch also disables optimizations that cannot be handled by the power-profiler. SYMDEBUG__NONE cmdline --program_level_compile -pm Program mode compilation Enable program mode compilation.

Using -g may hinder some optimizations to ensure that debugability is maintained, while this option will not hinder optimization. You will still be able to set breakpoints and profile on function-level boundaries, but you will not be able to single-step through code as with full debug ability. SYMDEBUG__DWARF SYMDEBUG__SKELETAL SYMDEBUG__NONE SYMDEBUG__COFF simple --symdebug:skeletal Symbolic debug for program analysis (default) Enable symbolic debug information for program analysis.

This information can then be read and interpreted by other tools. For example, the cache layout tool, clt6x, can be used to interpret the call graph information and produce a preferred function order that can be incorporated into the application link. The compiler can only generate one kind of analysis information for a given invocation of the compiler. GEN_PROFILE_INFO simple --verbose Display banner and function progress information Display progress information and toolset version when executing. QUIET SUPER_QUIET simple --verbose_diagnostics -pdv Verbose diagnostics Enable verbose diagnostic information from the parser, including the source line of the error and an indicator of the error position within the line. simple --visibility ONEOF required default,protected,hidden default protected hidden Specify visibility of global symbols. This option specifies the ELF visibility attribute of the global symbols. The ELF visibility attribute controls if and how the symbol can be accessed by other modules. simple --wchar_t ONEOF required 16,32 16 32 16 Set the size (in bits) of the C/C++ type wchar_t (16,32) Designate the size of the C/C++ type wchar_t. In COFF ABI mode only 16-bit wchar_t is allowed. In EABI mode users can choose either 16-bit or 32-bit wchar_t type. Note that objects built with 16-bit wchar_t are not compatible with 32-bit wchar_t objects. The default is 16-bit wchar_t. simple --write_diagnostics_file -pdf Output diagnostic to .err file Write diagnostics to an .err file instead of the standard output.

A dynamic component uses a unique index to access its DP value. This index can be allocated at run time by the dynamic loader or can be statically assigned via this option. The index value should be less than the DSBT size. simple --dsbt_size NUMBER required size The size of Data Segment Base Table (DSBT) in words The Data Segment Base Table (DSBT) contains the Data Page (DP) pointer for each component (executable or shared object) in a dynamic linking system. Each dynamic component in the system has an entry in the DSBT. This option specifies the size of the DSBT, and should be no less than the number of dynamic components in the system. simple --dynamic ONEOF optional exe,lib exe lib exe Generate dynamic executable or a dynamic library Generate a dynamic executable or a dynamic library for use in an application that is dynamically linked and relocated at load time simple --emit_warnings_as_errors -pdew Treat warnings as errors Treat warnings as errors NO_WARNINGS simple --entry_point -e STRING required symbol Specify program entry point for the output module Specify program entry point for the output module simple --export STRINGLIST required sym Export specified symbol This option makes the specified global symbol an exported definition. Global symbols that are given restricted (hidden) visibility by source code annotations will not be exported by this option. simple --fill_value -f HEXNUMBER required value Default fill value for holes in output sections Set the default fill value for filling holes in output sections. simple --fini STRING required sym Specify the symbol name of the finalization code This option sets the entry point symbol for finalization code. The dynamic loader calls the finalization code when it unloads a dynamically loaded object. When this option is used, the linker generates the DT_FINI dynamic tag and sets it to the address of the symbol. RETAIN --retain=$sym simple --forced_static_binding ONEOF optional on,off on off on Force all import references to bind during static linking Force all import references to bind during static linking. simple --globalize STRING required pattern Do not localize symbols matching pattern The option '--localize=l_pattern' makes the symbols matching the l_pattern hidden. The '--globalilze=g_pattern' option excludes symbols matching g_pattern from symbol localization provided g_pattern is more restrictive than l_pattern. simple --heap_size -heap --heap HEXNUMBER required size Heap size for C/C++ dynamic memory allocation Specify the maximum heap size for C/C++ dynamic memory allocation. simple --hide STRING required pattern Hide symbols matching pattern Hide the symbols matching the pattern by changing the name to empty string simple --import STRINGLIST required sym Import specified symbol This option makes specified global symbol an imported references. Global symbols that are given restricted (hidden) visibility by source code annotations will not be imported by this option. simple --init STRING required sym Specify the symbol name of the initialization code This option sets the entry point symbol for initialization code. The dynamic loader calls the initialization code when it loads a dynamically loaded object. When this option is used, the linker generates the DT_INIT dynamic tag and sets it to the address of the symbol. RETAIN --retain=$sym simple --issue_remarks Issue remarks Issue remarks simple --library -l STRINGLIST required file Include library file or command file as input Include library file or command file as input cmdline --linker_help -help --help Display usage information Display usage information. Followed by another option, will display detailed information on that option. simple --localize STRING required pattern Make the symbols matching pattern local Given a symbol name pattern, make all the symbols matching this pattern local simple --make_global -g STRINGLIST required symbol Don't make global symbol static if -h is specified Don't make global symbol static if -h is specified simple --make_static -h Make all global symbols static Make all global symbols static simple --map_file -m STRING required file Input and output sections listed into <file> Produce a listing of all input and output sections into <file>. simple --mapfile_contents STRING required attribute Display attribute settings in map file Enable the display of <attribute> or disable with no<attribute> in the linker generated map file. Multiple attributes can be specified by separating them with commas (e.g. --mapfile_contents=sections,nosymbols). Type --mapfile_contents=help for a list of attributes. simple --minimize_trampolines ONEOF optional postorder,off postorder off postorder Select trampoline minimization algorithm This option attempts to place sections so as to minimize the number of far call trampolines required, possibly at the expense of optimal memory packing. The argument selects a heuristic to use. The 'postorder' heuristic attempts to place functions before their callers so that the PC-relative offset is known when the caller is placed. simple --multithread Multi-threading is used; choose thread-safe RTS library Multi-threading is used; choose thread-safe RTS library simple --no_demangle Don't demangle symbol names in diagnostics Don't demangle symbol names in diagnostics simple --no_sym_merge -b No type merging in symbolic debugging information Disable type merging in symbolic debugging information. simple --no_symtable -s Strip symbol table and line number entries Strip symbol table and line number entries simple --no_warnings Suppress warnings Suppress warnings EMIT_WARNINGS_AS_ERRORS simple --output_file -o STRING required file Specify output file name Full filename of the output file. simple --preferred_order STRING required function Add <function> to preferred placement order list Insert a function into the preferred function order list for placement. Functions that are close to each other in the preferred function order list will tend to be placed close together (increase program locality between them). Static functions of the same name can be distinguished from each other by prefixing the function name with the path and file in which the function is defined followed by a ':' character to delimit the beginning of the function name. simple --priority -priority Search libraries in priority order Search libraries in priority order simple --ram_model -cr Link using RAM autoinitialization model Link using RAM autoinitialization model ROM_MODEL simple --relocatable -r Produce a relocatable output module Produce a relocatable output module simple --reread_libs -x Reread libraries; resolve backward references Reread libraries; resolve backward references simple --retain STRINGLIST required sym_or_scn_spec Specify symbols/sections to be retained by linker When --unused_section_elimination is enabled, the ELF linker does not include a section in the final link if it is not needed in the executable to resolve references. This option can be used to tell the linker to retain a list of sections that would otherwise be not retained. This option accepts the wild cards '*' and '?' and when wild cards are used, the argument should be in quotes. The following option parameters are accepted: --retain=symbol_spec retains sections that define symbol matching the argument. For ex, --retain='init*' retains sections that define symbols that start with 'init'. User may not specify --retain='*'. --retain=file_spec(scn_spec [,scn_spec ...]) retains sections matching scn_spec(s) from files matching file_spec. For ex, the argument '*(.initvec)' causes the linker to retain .initvec sections from all input files. NOTE: User can specify --retain='*(*)' to retain all the sections from all the input object files. Note that this does not prevent sections from library members from being optimized out. If you want to totally disable unused section elimination, please use --unused_section_elimination=off. --retain=ar_spec<mem_spec, [mem_spec ...]>(scn_spec, [scn_spec ...]) retains sections matching scn_spec(s) from members matching mem_spec(s) from archive files matching ar_spec. For ex, rts32eabi.lib<printf.obj>(.text) causes the linker to retain .text section from printf.obj in rts32eabi.lib. If the library is specified with -l option (-lrts32eabi.lib) the library search path is used to search the library. User may not specify '*<*>(*)'. simple --rom Create a ROM object This option allows the creation of ROM object module simple --rom_model -c Link using ROM autoinitialization model Link using ROM autoinitialization model RAM_MODEL simple --rpath STRINGLIST required dir Add directory to beginning of dynamic library search path The specified directory will be searched BEFORE the directories in LD_LIBRARY_PATH cmdline --run_abs -abs Produce absolute listing file Produce absolute listing file simple --runpath STRINGLIST required dir Add directory to end of dynamic library search path The specified directory will be searched AFTER the directories in LD_LIBRARY_PATH simple --scan_libraries -scanlibs Scan libraries for duplicate symbol definitions Check whether symbol definitions that are pulled into the link are duplicated in any of the libraries included in the build. This information is typically ignored as the linker will pull in the first definition it encounters. simple --search_path -i STRINGLIST required dir Add <dir> to library search path Alter the library-search algorithm to look in dir before looking in the default location. This option must appear before the -l option. simple --set_error_limit NUMBER required count Set error limit to <count> Set error limit to <count> simple --soname STRING required soname Specify ELF shared object file name Specify ELF shared object file name simple --stack_size -stack --stack HEXNUMBER required size Set C system stack size Set C system stack size simple --strict_compatibility ONEOF optional on,off on off on Strict compatibility checking Strict compatibility checking simple --symbol_map STRINGLIST required refname=defname Specify a symbol map, mapping refname to defname Symbol mapping allows a symbol reference to be resolved by a symbol with different name. Symbol mapping allows functions to be overridden with alternate definitions. This feature can be used to patch in alternate implementations, which provide patches (bug fixes) or alternate functionality. For example, the option --symbol_map='foo=foo_patch' makes the linker resolve any references to foo by the definition foo_patch. simple --trampoline_min_spacing HEXNUMBER required size Minimum space between non-adjacent trampolines When trampoline reservations are spaced more closely than this limit, try to make them adjacent. A higher value minimizes fragmentation, but may result in more trampolines. A lower value may reduce trampolines, at the expense of fragmentation and linker running time. Specifying 0 for this option disables coalescing. The default is 16K. simple --trampolines ONEOF optional on,off on off on Generate far call trampolines Generate far call trampolines simple --undef_sym -u STRINGLIST required sym Add <sym> to symbol table as an unresolved symbol Add <sym> to symbol table as an unresolved symbol simple --undefine STRING required name Undefine preprocessor macro _name_ Undefine preprocessor macro _name_ simple --unhide STRING required pattern Exclude symbols matching pattern from hiding The option --hide=hide_pattern makes the symbols matching the hide_pattern hidden. The --unhide=unhide_pattern option excludes symbols matching unhide_pattern from symbol hiding provided unhide_pattern is more restrictive than hide_pattern. simple --unused_section_elimination ONEOF optional on,off on off on Eliminate sections not needed in the executable In order to minimize memory use, the linker does not include a section that is not needed to resolve any references in the final executable. --unused_section_elimination=off can be used to disable this optimization. simple --verbose_diagnostics Verbose diagnostics Verbose diagnostics simple --warn_sections -w Warn if an unspecified output section is created Warn if an unspecified output section is created simple --xml_link_info -xml_link_info STRING required file Detailed link information data-base into <file> Produce a detailed link information data-base into the file named <file>. simple --zero_init ONEOF optional on,off on off on Zero initialize ELF uninitialized sections This option indicates that the linker should generate compressed cinit table records that zero initializes ELF uninitialized sections during boot.
