Since the expected instructions reply on the vectorization occurrence, we don't expect vectorization gets disabled by cost model. To make it not fragile, the fix is to force it without vect cost model. gcc/testsuite/ChangeLog: * gcc.target/powerpc/conv-vectorize-1.c: Add option -fno-vect-cost-model. * gcc.target/powerpc/conv-vectorize-2.c: Likewise. --- diff --git a/gcc/testsuite/gcc.target/powerpc/conv-vectorize-1.c b/gcc/testsuite/gcc.target/powerpc/conv-vectorize-1.c index d96db14..8b8c88b 100644 --- a/gcc/testsuite/gcc.target/powerpc/conv-vectorize-1.c +++ b/gcc/testsuite/gcc.target/powerpc/conv-vectorize-1.c @@ -1,5 +1,5 @@ /* { dg-require-effective-target powerpc_vsx_ok } */ -/* { dg-options "-O2 -ftree-vectorize -mvsx" } */ +/* { dg-options "-O2 -ftree-vectorize -mvsx -fno-vect-cost-model" } */ /* Test vectorizer can exploit vector conversion instructions to convert unsigned/signed long long to float. */ diff --git a/gcc/testsuite/gcc.target/powerpc/conv-vectorize-2.c b/gcc/testsuite/gcc.target/powerpc/conv-vectorize-2.c index 5dd5dea..06ae4e2 100644 --- a/gcc/testsuite/gcc.target/powerpc/conv-vectorize-2.c +++ b/gcc/testsuite/gcc.target/powerpc/conv-vectorize-2.c @@ -1,5 +1,5 @@ /* { dg-require-effective-target powerpc_vsx_ok } */ -/* { dg-options "-O2 -ftree-vectorize -mvsx" } */ +/* { dg-options "-O2 -ftree-vectorize -mvsx -fno-vect-cost-model" } */ /* Test vectorizer can exploit vector conversion instructions to convert float to unsigned/signed long long. */
