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/pr40501.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr40501.c (limited to 'gcc/testsuite/gcc.dg/pr40501.c') diff --git a/gcc/testsuite/gcc.dg/pr40501.c b/gcc/testsuite/gcc.dg/pr40501.c new file mode 100644 index 000000000..0e43e63c6 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr40501.c @@ -0,0 +1,24 @@ +/* { dg-do compile { target alpha*-*-* ia64*-*-* x86_64-*-* s390x-*-* } } */ +/* { dg-options "-O2" } */ +/* { dg-require-effective-target lp64 } */ + +/* PR middle-end/40501 */ + +/* This once failed due to the bswap pass missing to add the type + casts of the signed argument and result to the proper unsigned + types. */ + +typedef long int int64_t; + +int64_t +swap64 (int64_t n) +{ + return (((n & (((int64_t) 0xff) )) << 56) | + ((n & (((int64_t) 0xff) << 8)) << 40) | + ((n & (((int64_t) 0xff) << 16)) << 24) | + ((n & (((int64_t) 0xff) << 24)) << 8) | + ((n & (((int64_t) 0xff) << 32)) >> 8) | + ((n & (((int64_t) 0xff) << 40)) >> 24) | + ((n & (((int64_t) 0xff) << 48)) >> 40) | + ((n & (((int64_t) 0xff) << 56)) >> 56)); +} -- cgit v1.2.3
