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/pr46212.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr46212.c (limited to 'gcc/testsuite/gcc.dg/pr46212.c') diff --git a/gcc/testsuite/gcc.dg/pr46212.c b/gcc/testsuite/gcc.dg/pr46212.c new file mode 100644 index 000000000..9dbb601e0 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr46212.c @@ -0,0 +1,23 @@ +/* PR rtl-optimization/46212 */ +/* { dg-do compile } */ +/* { dg-options "-O3 -funroll-loops" } */ +/* { dg-options "-O3 -funroll-loops -march=i386" { target { { i686-*-* x86_64-*-* } && ilp32 } } } */ + +static inline unsigned +foo (void *x) +{ + unsigned y = *(volatile unsigned *) (x); + return (y >> 24) | ((y >> 8) & 0xff00) | ((y & 0xff00) << 8) | (y << 24); +} + +void +bar (void *x, void *y, int z) +{ + unsigned c; + while (z--) + { + c = foo (y); + *(unsigned *) x = (c & 0xf80000) >> 9 | (c & 0xf800) >> 6 + | (c & 0xf8) >> 3 | (c & 0x80000000) >> 16; + } +} -- cgit v1.2.3
