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/pr47148.c | 32 +++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr47148.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr47148.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr47148.c b/gcc/testsuite/gcc.c-torture/execute/pr47148.c new file mode 100644 index 000000000..8363631a9 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr47148.c @@ -0,0 +1,32 @@ +/* PR tree-optimization/47148 */ + +static inline unsigned +bar (unsigned x, unsigned y) +{ + if (y >= 32) + return x; + else + return x >> y; +} + +static unsigned a = 1, b = 1; + +static inline void +foo (unsigned char x, unsigned y) +{ + if (!y) + return; + unsigned c = (0x7000U / (x - 2)) ^ a; + unsigned d = bar (a, a); + b &= ((a - d) && (a - 1)) + c; +} + +int +main (void) +{ + foo (1, 1); + foo (-1, 1); + if (b && ((unsigned char) -1) == 255) + __builtin_abort (); + return 0; +} -- cgit v1.2.3
