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/g++.dg/torture/stackalign/unwind-2.C | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/g++.dg/torture/stackalign/unwind-2.C (limited to 'gcc/testsuite/g++.dg/torture/stackalign/unwind-2.C') diff --git a/gcc/testsuite/g++.dg/torture/stackalign/unwind-2.C b/gcc/testsuite/g++.dg/torture/stackalign/unwind-2.C new file mode 100644 index 000000000..791eeb551 --- /dev/null +++ b/gcc/testsuite/g++.dg/torture/stackalign/unwind-2.C @@ -0,0 +1,29 @@ +/* { dg-do run { target { { i?86-*-* x86_64-*-* } && ilp32 } } } */ + +#include "test-unwind.h" + +#if !defined __PIC__ && !defined __USING_SJLJ_EXCEPTIONS__ +/* Test situation 2: stack really realign with DRAP reg CX */ +void __attribute__ ((noinline)) +foo () +{ + int __attribute__ ((aligned(64))) a=4; + char * s = (char *) __builtin_alloca (a + 1); + + copy (s, a); + if (__builtin_strncmp (s, "good", a) != 0) + { +#ifdef DEBUG + s[a] = '\0'; + printf ("Failed: %s != good\n", s); +#endif + abort (); + } + + if (check_int (&a, __alignof__(a)) != a) + abort (); + + ALTER_REGS(); + throw a; +} +#endif -- cgit v1.2.3
