2.1.157 --translate_gcc
This option 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 RVCT 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 RVCT 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, RVCT default behavior is retained, and no defaults are set
for targeting ARM Linux. RVCT library paths and option defaults remained unchanged.
Restrictions
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
and --no_relaxed_ref_def, and --signed_bitfields and --unsigned_bitfields.
