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/fold-bitand-1.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/fold-bitand-1.c (limited to 'gcc/testsuite/gcc.dg/fold-bitand-1.c') diff --git a/gcc/testsuite/gcc.dg/fold-bitand-1.c b/gcc/testsuite/gcc.dg/fold-bitand-1.c new file mode 100644 index 000000000..f490b153b --- /dev/null +++ b/gcc/testsuite/gcc.dg/fold-bitand-1.c @@ -0,0 +1,33 @@ +/* { dg-do compile } */ +/* { dg-options "-w -fdump-tree-original" } */ + +char c1 __attribute__ ((aligned (1))); +char c2 __attribute__ ((aligned (2))); +char c4 __attribute__ ((aligned (4))); +char c8 __attribute__ ((aligned (8))); +unsigned f1(void) +{ + return 3 & (__SIZE_TYPE__)&c1; +} + +unsigned f2(void) +{ + return 3 & (__SIZE_TYPE__)&c2; +} + +unsigned f3(void) +{ + return 3 & (__SIZE_TYPE__)&c4; +} + +unsigned f4(void) +{ + return 3 & (__SIZE_TYPE__)&c8; +} + +/* { dg-final { scan-tree-dump-times "\&c1 \& 3" 1 "original" } } */ +/* { dg-final { scan-tree-dump-times "\&c2 \& 3" 1 "original" } } */ +/* { dg-final { scan-tree-dump-times "\&c4 \& 3" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "\&c8 \& 3" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "return 0" 2 "original" } } */ +/* { dg-final { cleanup-tree-dump "original" } } */ -- cgit v1.2.3
