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/compile/pr37056.c | 28 +++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr37056.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr37056.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr37056.c b/gcc/testsuite/gcc.c-torture/compile/pr37056.c new file mode 100644 index 000000000..f9285e2c7 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr37056.c @@ -0,0 +1,28 @@ +extern void abort (void); + +static union { + char buf[12 * sizeof (long long)]; +} u; + +int main () +{ + int off, len, i; + char *p, *q; + + for (off = 0; off < (sizeof (long long)); off++) + for (len = 1; len < (10 * sizeof (long long)); len++) + { + for (i = 0; i < (12 * sizeof (long long)); i++) + u.buf[i] = 'a'; + p = (__extension__ (__builtin_constant_p ('\0') && ('\0') == '\0' + ?
