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/20050826-1.c | 44 ++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20050826-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20050826-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20050826-1.c b/gcc/testsuite/gcc.c-torture/execute/20050826-1.c new file mode 100644 index 000000000..bc7f94032 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20050826-1.c @@ -0,0 +1,44 @@ +/* PR rtl-optimization/23561 */ + +struct A +{ + char a1[1]; + char a2[5]; + char a3[1]; + char a4[2048 - 7]; +} a; + +typedef __SIZE_TYPE__ size_t; +extern void *memset (void *, int, size_t); +extern void *memcpy (void *, const void *, size_t); +extern int memcmp (const void *, const void *, size_t); +extern void abort (void); + +void +bar (struct A *x) +{ + size_t i; + if (memcmp (x, "\1HELLO\1", sizeof "\1HELLO\1")) + abort (); + for (i = 0; i < sizeof (x->a4); i++) + if (x->a4[i]) + abort (); +} + +int +foo (void) +{ + memset (&a, 0, sizeof (a)); + a.a1[0] = 1; + memcpy (a.a2, "HELLO", sizeof "HELLO"); + a.a3[0] = 1; + bar (&a); + return 0; +} + +int +main (void) +{ + foo (); + return 0; +} -- cgit v1.2.3
