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/20011024-1.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20011024-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20011024-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20011024-1.c b/gcc/testsuite/gcc.c-torture/execute/20011024-1.c new file mode 100644 index 000000000..5b871bbb9 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20011024-1.c @@ -0,0 +1,22 @@ +/* Test whether store motion recognizes pure functions as potentially reading + any memory. */ + +typedef __SIZE_TYPE__ size_t; +extern void *memcpy (void *dest, const void *src, size_t n); +extern size_t strlen (const char *s); +extern int strcmp (const char *s1, const char *s2) __attribute__((pure)); + +char buf[50]; + +static void foo (void) +{ + if (memcpy (buf, "abc", 4) != buf) abort (); + if (strcmp (buf, "abc")) abort (); + memcpy (buf, "abcdefgh", strlen ("abcdefgh") + 1); +} + +int main (void) +{ + foo (); + return 0; +} -- cgit v1.2.3
