PR tree-optimization/71488
* gcc.target/i386/i386.exp (check_effective_target_sse4): Move to ...
* lib/target-supports.exp: ... here.
(check_sse4_hw_available): New procedure.
(check_effective_target_sse4_runtime): Ditto.
* g++.dg/pr71488.C (dg-additional-options): Use -msse4 instead of
-march=westmere for sse4_runtime targets.
* gcc.dg/vect/vect-bool-cmp.c: Include "tree-vect.h".
(dg-additional-options): Use for sse4_runtime targets.
(main): Call check_vect ().
(dg-final): Perform scan only for sse4_runtime targets.
Tested on x86_64-linux-gnu {,-m32} AVX target and SSE2-only target.
Committed to mainline SVN.
Uros.
