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. --- diff --git a/gcc/testsuite/gcc.dg/pr78408-1.c b/gcc/testsuite/gcc.dg/pr78408-1.c index 94e2090b374f..dc9870ac6afc 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 *);
