The following tables list the linker options. See Section 11 of this document and Section 12 for details on these options.
| Option | Alias | Description |
|---|---|---|
| --run_linker | -z | Enables linking. |
| --output_file=file | -o | Names the executable output file. The default filename is a .out file. |
| --map_file=file | -m | Produces a map or listing of the input and output sections, including holes, and places the listing in file. |
| --stack_size=size | [-]-stack | Sets C system stack size to sizebytes and defines a global symbol that specifies the stack size. Default = 1K bytes. |
| --heap_size=size | [-]-heap | Sets heap size (for the dynamic memory allocation in C) to sizebytes and defines a global symbol that specifies the heap size. Default = 1K bytes. |
| Option | Alias | Description |
|---|---|---|
| --library=file | -l | Names an archive library or link command file as linker input. |
| --disable_auto_rts | Disables the automatic selection of a run-time-support library. See Section 11.3.1.1. | |
| --priority | -priority | Satisfies unresolved references by the first library that contains a definition for that symbol. |
| --reread_libs | -x | Forces rereading of libraries, which resolves back references. |
| --search_path=pathname |
-I
|
Alters library-search algorithms to look in a directory named with pathname before looking in the default location. This option must appear before the --library option. |
| Option | Alias | Description |
|---|---|---|
| --define=name=value | Predefines name as a preprocessor macro. | |
| --undefine=name | Removes the preprocessor macro name. | |
| --disable_pp | Disables preprocessing for command files. |
| Option | Alias | Description |
|---|---|---|
| --diag_error=num | Categorizes the diagnostic identified by num as an error. | |
| --diag_remark=num | Categorizes the diagnostic identified by num as a remark. | |
| --diag_suppress=num | Suppresses the diagnostic identified by num. | |
| --diag_warning=num | Categorizes the diagnostic identified by num as a warning. | |
| --display_error_number | Displays a diagnostic's identifiers along with its text. | |
| --emit_references:file[=file] | Emits a file containing section information. The information includes section size, symbols defined, and references to symbols. | |
| --emit_warnings_as_errors | -pdew | Treat warnings as errors. |
| --issue_remarks | Issues remarks (non-serious warnings). | |
| --no_demangle | Disables demangling of symbol names in diagnostic messages. | |
| --no_warnings | Suppresses diagnostic warnings (errors are still issued). | |
| --set_error_limit=count | Sets the error limit to count. The linker abandons linking after this number of errors. (The default is 100.) | |
| --verbose_diagnostics | Provides verbose diagnostic messages that display the original source with line-wrap. |
| Option | Alias | Description |
|---|---|---|
| --absolute_exe | -a | Produces an absolute, executable object file. This is the default; if neither --absolute_exe nor --relocatable is specified, the linker acts as if --absolute_exe were specified. |
| --mapfile_contents=attribute | Controls the information that appears in the map file. | |
| --relocatable | -r | Produces a nonexecutable, relocatable output object file. |
| --rom | Creates a ROM object. | |
| --xml_link_info=file | Generates a well-formed XML file containing detailed information about the result of a link. |
| Option | Alias | Description |
|---|---|---|
| --entry_point=symbol | -e | Defines a global symbol that specifies the primary entry point for the executable object file. |
| --globalize=pattern | Changes the symbol linkage to global for symbols that match pattern. | |
| --hide=pattern | Hides symbols that match the specified pattern. | |
| --localize=pattern | Make the symbols that match the specified pattern local. | |
| --make_global=symbol | -g | Makes symbol global (overrides -h). |
| --make_static | -h | Makes all global symbols static. |
| --no_symtable | -s | Strips symbol table information and line number entries from the executable object file. |
| --retain={symbol|
section specification} |
Specifies a symbol or section to be retained by the linker. | |
| --scan_libraries | -scanlibs | Scans all libraries for duplicate symbol definitions. |
| --symbol_map=refname=defname | Specifies a symbol mapping; references to the refname symbol are replaced with references to the defname symbol. | |
| --undef_sym=symbol | -u | Adds symbol to the symbol table as an unresolved symbol. |
| --unhide=pattern | Excludes symbols that match the specified pattern from being hidden. | |
| Option | Alias | Description |
|---|---|---|
| --arg_size=size | --args | Reserve size bytes for the argc/argv memory area. |
| --cinit_compression[=type] | Specifies the type of compression to apply to the C auto initialization data. The default if this option is specified with no type is lzss for Lempel-Ziv-Storer-Szymanski compression. | |
| --copy_compression[=type] | Compresses data copied by linker copy tables. The default if this option is specified with no type is lzss for Lempel-Ziv-Storer-Szymanski compression. | |
| --fill_value=value | -f | Sets default fill value for holes within output sections |
| --ram_model | -cr | Initializes variables at load time. |
| --rom_model | -c | Autoinitializes variables at run time. |
| --trampolines[=off|on] | Generates far call trampolines. Default is on. |
| Option | Alias | Description |
|---|---|---|
| --compress_dwarf[=off|on] | Aggressively reduces the size of DWARF information from input object files. Default is on. | |
| --linker_help | [-]-help | Displays information about syntax and available options. |
| --minimize_trampolines[=off | postorder] | Places sections to minimize number of far trampolines required. Default is postorder. | |
| --preferred_order=function | Prioritizes placement of functions. | |
| --strict_compatibility[=off|on] | Performs more conservative and rigorous compatibility checking of input object files. Default is on. | |
| --zero_init=[off|on] | Controls preinitialization of uninitialized variables. Default is on. |
