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/vrp-6.c | 33 +++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/vrp-6.c (limited to 'gcc/testsuite/gcc.c-torture/execute/vrp-6.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/vrp-6.c b/gcc/testsuite/gcc.c-torture/execute/vrp-6.c new file mode 100644 index 000000000..7c6a1750f --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/vrp-6.c @@ -0,0 +1,33 @@ +#include + +extern void exit (int); +extern void abort (); + +void test01(unsigned int a, unsigned int b) +{ + if (a < 5) + abort(); + if (b < 5) + abort(); + if (a - b != 5) + abort(); +} + +void test02(unsigned int a, unsigned int b) +{ + if (a >= 12) + if (b > 15) + if (a - b < UINT_MAX - 15U) + abort (); +} + +int main(int argc, char *argv[]) +{ + unsigned x = 0x80000000; + test01(x + 5, x); + test02(14, 16); + exit (0); +} + + + -- cgit v1.2.3
