Subject: [PATCH 2/2] PR target/71056: Don't use vectorized builtins when NEON
|
||
|
is not available
|
||
|
|
||
|
PR target/71056
|
||
|
* config/arm/arm-builtins.c (arm_builtin_vectorized_function): Return
|
||
|
NULL_TREE early if NEON is not available. Remove now redundant check
|
||
|
in ARM_CHECK_BUILTIN_MODE.
|
||
|
|
||
|
* gcc.target/arm/pr71056.c: New test.
