--- Comment #3 from Christophe Lyon <clyon at gcc dot gnu.org> ---
Unfortunately this is causing many regressions in the GCC testsuite.

For instance:
--target arm-none-linux-gnueabi
--with-mode arm
--with-cpu cortex-a9
--with-fpu default
gcc.target/arm/armv8_2-fp16-neon-1.c is compiled with
-mfloat-abi=softfp -march=armv8.2-a+fp16

/gcc/testsuite/gcc.target/arm/armv8_2-fp16-neon-1.c: In function
'test_vceqz_16x4':
/gcc/testsuite/gcc.target/arm/armv8_2-fp16-neon-1.c:139:13: warning: implicit
declaration of function 'vceqz_f16'; did you mean 'vceqq_u16'?

--target arm-none-linux-gnueabi
--with-mode arm
--with-cpu cortex-a9
--with-fpu default
Dejagnu flags: -march=armv5t
gcc.target/arm/aes-fuse-1.c is compiled with

-march=armv5t -mfpu=crypto-neon-fp-armv8 -mfloat-abi=softfp -mcpu=cortex-a72
cc1: warning: switch '-mcpu=cortex-a72' conflicts with switch '-march=armv5t'
FAIL: gcc.target/arm/aes-fuse-1.c (test for excess errors)

For a full picture of the regressions I noticed:

(click on "log" to download the corresponding gcc.log and see the error
messages)
(you can ignore the regressions in g++, they are caused by a previous commit)
