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.dg/pr9814-1.c | 107 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 107 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr9814-1.c (limited to 'gcc/testsuite/gcc.dg/pr9814-1.c') diff --git a/gcc/testsuite/gcc.dg/pr9814-1.c b/gcc/testsuite/gcc.dg/pr9814-1.c new file mode 100644 index 000000000..51b79f783 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr9814-1.c @@ -0,0 +1,107 @@ +/* PR tree-optimization/9814 */ +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +extern void abort(void); + +int test1(int x) +{ + if (x & 2) + x |= 2; + return x; +} + +int test2(int x) +{ + if (!(x & 2)) + x |= 2; + return x; +} + +int test3(int x) +{ + if (x & 2) + x ^= 2; + return x; +} + +int test4(int x) +{ + if (!(x & 2)) + x ^= 2; + return x; +} + +int test5(int x) +{ + if (x & 2) + x &= ~2; + return x; +} + +int test6(int x) +{ + if (!(x & 2)) + x &= ~2; + return x; +} + +int main() +{ + if (test1(0) != 0) + abort(); + if (test1(2) != 2) + abort(); + if (test1(5) != 5) + abort(); + if (test1(7) != 7) + abort(); + + if (test2(0) != 2) + abort(); + if (test2(2) != 2) + abort(); + if (test2(5) != 7) + abort(); + if (test2(7) != 7) + abort(); + + if (test3(0) != 0) + abort(); + if (test3(2) != 0) + abort(); + if (test3(5) != 5) + abort(); + if (test3(7) != 5) + abort(); + + if (test4(0) != 2) + abort(); + if (test4(2) != 2) + abort(); + if (test4(5) != 7) + abort(); + if (test4(7) != 7) + abort(); + + if (test5(0) != 0) + abort(); + if (test5(2) != 0) + abort(); + if (test5(5) != 5) + abort(); + if (test5(7) != 5) + abort(); + + if (test6(0) != 0) + abort(); + if (test6(2) != 2) + abort(); + if (test6(5) != 5) + abort(); + if (test6(7) != 7) + abort(); + + return 0; +} + -- cgit v1.2.3
