From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c | 49 ++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c (limited to 'gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c') diff --git a/gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c b/gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c new file mode 100644 index 000000000..139b74ed9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/stackalign/alloca-2.c @@ -0,0 +1,49 @@ +/* PR middle-end/37009 */ +/* { dg-do run { target { { i?86-*-* x86_64-*-* } && ilp32 } } } */ +/* { dg-options "-msse2" } */ +/* { dg-require-effective-target sse2_runtime } */ + +#include +#include "check.h" + +#ifndef ALIGNMENT +#define ALIGNMENT 16 +#endif + +typedef int aligned __attribute__((aligned(ALIGNMENT))); + +void +bar (char *p, int size) +{ + __builtin_strncpy (p, "good", size); +} + +void +__attribute__ ((noinline)) +foo (__m128 x, __m128 y ,__m128 z , int size) +{ + char *p = __builtin_alloca (size + 1); + aligned i; + + bar (p, size); + if (__builtin_strncmp (p, "good", size) != 0) + { +#ifdef DEBUG + p[size] = '\0'; + printf ("Failed: %s != good\n", p); +#endif + abort (); + } + + if (check_int (&i, __alignof__(i)) != i) + abort (); +} + +int +main (void) +{ + __m128 x = { 1.0 }; + foo (x, x, x, 5); + + return 0; +} -- cgit v1.2.3
