This patch fixes (PR97327) the warning -mcpu=cortex-m55 conflicts with -march=armv8.1-m.main for -mfloat-abi=soft by adding the isa_bit_mve_float to clearing FP bit list. The following combination are fixed with this patch: $ cat bug.c int main(){ return 0; } $ arm-none-eabi-gcc -mcpu=cortex-m55 -mfloat-abi=soft bug.c -c $ arm-none-eabi-gcc -mcpu=cortex-m55 -mfloat-abi=soft -march=armv8.1-m.main+mve bug.c -c Before this patch for above combinations: cc1: warning: switch '-mcpu=cortex-m55' conflicts with '-march=armv8.1-m.main' switch After this patch for above combinations no warning/errors. gcc/ChangeLog: 2020-10-16 Srinath Parvathaneni <srinath.parvathaneni@arm.com> PR target/97327 * config/arm/arm.c (fp_bitlist): Add isa_bit_mve_float to FP bits array. gcc/testsuite/ChangeLog: PR target/97327 * gcc.target/arm/mve/intrinsics/pr97327.c: New test.
