--translate_gcc
Helps to emulate GCC by enabling the translation of command lines from the GNU tools.
Usage
You can use this option to provide either of the following:
A full GCC emulation targeting ARM Linux.
A subset of full GCC emulation in the form of translating individual GCC command-line arguments into their ARM compiler equivalents.
To provide a full GCC emulation, you must also use
--arm_linux_config_file. This combination of options selects the
appropriate GNU header files and libraries specified by the configuration file, and includes
changes to some default behaviors.
To translate individual GCC command-line arguments into their ARM compiler equivalents
without aiming for full GCC emulation, use --translate_gcc to emulate
gcc, but do not use it with --arm_linux_config_file.
Because you are not aiming for full GCC emulation with this method, the default behavior of
the ARM compilation tools is retained, and no defaults are set for targeting ARM Linux. The
library paths and option defaults for the ARM compilation tools remained unchanged.
To selectively specify options that are not to be translated, use
-Warmcc.
Specifying multiple GNU translation modes on the same command line is ambiguous to the
compiler. The first specified translation mode is used, and the compiler generates a warning
message. For example, given armcc --translate_gcc --translate_gld, the
compiler uses --translate_gcc, ignores --translate_gld,
and generates a warning message.
If you specify an ARM Linux configuration file on the command line and you use
--translate_gcc, this alters the default settings for:
-
--bss_threshold. --relaxed_ref_def,--no_relaxed_ref_def.--signed_bitfields,--unsigned_bitfields.
