Compiler Command-line Options
• a subset of full GCC emulation in the form of translating individual GCC
command-line arguments into their RVCT equivalents.
To provide a full ARM Linux 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 GCC command-line arguments into their RVCT equivalents without aiming
for full GCC emulation, use --translate_g++ to emulate g++, 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_g++, this alters the default settings for --exceptions and --no_exceptions,
--bss_threshold, --relaxed_ref_def and --no_relaxed_ref_def, and --signed_bitfields
and --unsigned_bitfields.
