Hi,
The gcc.target/aarch64/_Float16_*.c tests fail if we are testing with
-mcpu= option which is not an armv8.2-a processor. This is because
independent of the order -mcpu=/-march= options, -mcpu= overrides the
-march= option.
Committed as obvious after testing on aarch64-linux-gnu with
"--target_board=unix/\{,-mcpu=thunderx,-mcpu=thunderx2t99,-march=armv8-a,-march=armv8.1-a,-march=armv8.2-a\}".
Thanks,
Andrew Pinski
ChangeLog:
* gcc.target/aarch64/_Float16_1.c: Skip if supplied a -mcpu= option.
* gcc.target/aarch64/_Float16_2.c: Likewise
* gcc.target/aarch64/_Float16_3.c: Likewise.
