Hi all,
This patch will ensure testsuite/gcc.target/arm/fixed_float_conversion.c
is checked only when "-mfpu=vfp3 -mfloat-abi=softfp" is applicable for
the target.
Accordingly, two procs (check_effective_target_arm_vfp3_ok and
add_options_for_arm_vfp3) are added into
gcc/testsuite/lib/target-supports.exp.
I have also update related documentation.
Okay for trunk?
Kind regards,
Renlin Li
