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.c-torture/execute/20071108-1.c | 53 ++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20071108-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20071108-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20071108-1.c b/gcc/testsuite/gcc.c-torture/execute/20071108-1.c new file mode 100644 index 000000000..f5460579b --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20071108-1.c @@ -0,0 +1,53 @@ +/* PR tree-optimization/32575 */ + +extern void abort (void); + +struct S +{ + void *s1, *s2; + unsigned char s3, s4, s5; +}; + +__attribute__ ((noinline)) +void * +foo (void) +{ + static struct S s; + return &s; +} + +__attribute__ ((noinline)) +void * +bar () +{ + return (void *) 0; +} + +__attribute__ ((noinline)) +struct S * +test (void *a, void *b) +{ + struct S *p, q; + p = foo (); + if (p == 0) + { + p = &q; + __builtin_memset (p, 0, sizeof (*p)); + } + p->s1 = a; + p->s2 = b; + if (p == &q) + p = 0; + return p; +} + +int +main (void) +{ + int a; + int b; + struct S *z = test ((void *) &a, (void *) &b); + if (z == 0 || z->s1 != (void *) &a || z->s2 != (void *) &b || z->s3 || z->s4) + abort (); + return 0; +} -- cgit v1.2.3
