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.target/powerpc/ppc-and-1.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/ppc-and-1.c (limited to 'gcc/testsuite/gcc.target/powerpc/ppc-and-1.c') diff --git a/gcc/testsuite/gcc.target/powerpc/ppc-and-1.c b/gcc/testsuite/gcc.target/powerpc/ppc-and-1.c new file mode 100644 index 000000000..3d4237ce9 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/ppc-and-1.c @@ -0,0 +1,20 @@ +/* { dg-do compile { target { powerpc*-*-* && lp64 } } } */ +/* { dg-options "-O2" } */ + +/* { dg-final { scan-assembler "rlwinm r?\[0-9\]+,r?\[0-9\]+,0,0,30" } } */ +/* { dg-final { scan-assembler "rlwinm r?\[0-9\]+,r?\[0-9\]+,0,29,30" } } */ +/* { dg-final { scan-assembler-not "rldicr" } } */ + +/* Origin:Pete Steinmetz */ + +/* PR 16457 - use rlwinm insn. */ + +char *foo1 (char *p, unsigned int x) +{ + return p - (x & ~1); +} + +char *foo2 (char *p, unsigned int x) +{ + return p - (x & 6); +} -- cgit v1.2.3
