From cb2c60206f4f2218f84ccde21663b00de068d8c7 Mon Sep 17 00:00:00 2001 From: Kewen Lin Date: Sun, 8 Mar 2020 21:55:11 -0500 Subject: [PATCH] [testsuite] Fix PR94019 to check vector char when vect_hw_misalign As PR94019 shows, without misaligned vector access support but with realign load, the vectorized loop will end up with realign scheme. It generates mask (control vector) with return type vector signed char which breaks the not check. gcc/testsuite/ChangeLog 2020-03-09 Kewen Lin PR testsuite/94019 * gcc.dg/vect/vect-over-widen-17.c: Don't expect vector char if it's without misaligned vector access support. --- gcc/testsuite/ChangeLog | 6 ++++++ gcc/testsuite/gcc.dg/vect/vect-over-widen-17.c | 5 ++++- 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/gcc/testsuite/ChangeLog b/gcc/testsuite/ChangeLog index 2126a24c3ea..b72b9cb1928 100644 --- a/gcc/testsuite/ChangeLog +++ b/gcc/testsuite/ChangeLog @@ -1,3 +1,9 @@ +2020-03-09 Kewen Lin + + PR testsuite/94019 + * gcc.dg/vect/vect-over-widen-17.c: Don't expect vector char if it's + without misaligned vector access support. + 2020-03-09 Kewen Lin PR testsuite/94023 diff --git a/gcc/testsuite/gcc.dg/vect/vect-over-widen-17.c b/gcc/testsuite/gcc.dg/vect/vect-over-widen-17.c index 04482607b04..333d74ac3e7 100644 --- a/gcc/testsuite/gcc.dg/vect/vect-over-widen-17.c +++ b/gcc/testsuite/gcc.dg/vect/vect-over-widen-17.c @@ -41,6 +41,9 @@ main (void) } /* { dg-final { scan-tree-dump-not {vect_recog_over_widening_pattern: detected} "vect" } } */ -/* { dg-final { scan-tree-dump-not {vector[^\n]*char} "vect" } } */ +/* On Power, if there is no vect_hw_misalign support, unaligned vector access + adopts realign_load scheme.
