From b34fa88becb6367229074f25ef9e2de6f4594b58 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Wed, 29 Sep 2021 14:32:32 +0200 Subject: [PATCH] testsuite/102517 - fix FAIL of gcc.dg/pr78408-1.c with OImode availability This fixes the testcase which looks for variants of memcpy after memset folding which is disturbed when we expand the memcpy inline earlier which in fact performs the desired optimization but makes the dump file not match. For the ease of testing the following adjusts the smaller structure size to be no longer power-of-two which avoids the inline expansion. 2021-09-29 Richard Biener PR testsuite/102517 * gcc.dg/pr78408-1.c: Make S not power-of-two size. --- gcc/testsuite/gcc.dg/pr78408-1.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/testsuite/gcc.dg/pr78408-1.c b/gcc/testsuite/gcc.dg/pr78408-1.c index 94e2090..dc9870a 100644 --- a/gcc/testsuite/gcc.dg/pr78408-1.c +++ b/gcc/testsuite/gcc.dg/pr78408-1.c @@ -3,7 +3,7 @@ /* { dg-options "-O2 -fdump-tree-fab1-details" } */ /* { dg-final { scan-tree-dump-times "after previous" 17 "fab1" } } */ -struct S { char a[32]; }; +struct S { char a[33]; }; struct T { char a[65536]; }; void bar (int, struct S *, struct S *, struct T *, struct T *); void baz (char *, char *); -- 2.7.4
