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/pr33992.c | 37 +++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr33992.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr33992.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr33992.c b/gcc/testsuite/gcc.c-torture/execute/pr33992.c new file mode 100644 index 000000000..743361061 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr33992.c @@ -0,0 +1,37 @@ +extern void abort (); + +void __attribute__((noinline)) +bar (unsigned long long i) +{ + if (i) + abort (); +} + +void __attribute__((always_inline)) +foo (unsigned long long *r) +{ + int i; + + for (i = 0; ; i++) + if (*r & ((unsigned long long)1 << (63 - i))) + break; + + bar (i); +} + +void __attribute__((noinline)) +do_test (unsigned long long *r) +{ + int i; + + for (i = 0; i < 2; ++i) + foo (r); +} + +int main() +{ + unsigned long long r = 0x8000000000000001ull; + + do_test (&r); + return 0; +} -- cgit v1.2.3
