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/usmul.c | 33 +++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/usmul.c (limited to 'gcc/testsuite/gcc.c-torture/execute/usmul.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/usmul.c b/gcc/testsuite/gcc.c-torture/execute/usmul.c new file mode 100644 index 000000000..28501b53f --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/usmul.c @@ -0,0 +1,33 @@ +int __attribute__ ((noinline)) foo (short x, unsigned short y) +{ + return x * y; +} + +int __attribute__ ((noinline)) bar (unsigned short x, short y) +{ + return x * y; +} + +int main () +{ + if (foo (-2, 0xffff) != -131070) + abort (); + if (foo (2, 0xffff) != 131070) + abort (); + if (foo (-32768, 0x8000) != -1073741824) + abort (); + if (foo (32767, 0x8000) != 1073709056) + abort (); + + if (bar (0xffff, -2) != -131070) + abort (); + if (bar (0xffff, 2) != 131070) + abort (); + if (bar (0x8000, -32768) != -1073741824) + abort (); + if (bar (0x8000, 32767) != 1073709056) + abort (); + + exit (0); +} + -- cgit v1.2.3
