Another patch to extend uses of built_in_function to combined_fn, this time in tree-vect-patterns.c. The old code didn't handle the long double pow variants, but I think that's because noone had a target that would benefit rather than because the code would mishandle them.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. OK to install? Thanks, Richard gcc/ * tree-vect-patterns.c: Include case-cfn-macros.h. (vect_recog_pow_pattern): Use combined_fn instead of built-in codes. diff --git a/gcc/tree-vect-patterns.c b/gcc/tree-vect-patterns.c index d003d33..bab9a4f 100644 --- a/gcc/tree-vect-patterns.c +++ b/gcc/tree-vect-patterns.c @@ -39,6 +39,7 @@ along with GCC; see the file COPYING3.
