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/i386/pr31167.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr31167.c (limited to 'gcc/testsuite/gcc.target/i386/pr31167.c') diff --git a/gcc/testsuite/gcc.target/i386/pr31167.c b/gcc/testsuite/gcc.target/i386/pr31167.c new file mode 100644 index 000000000..43d9f848b --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr31167.c @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target int128 } */ +/* { dg-options "-O" } */ + +typedef int int32_t; + +int32_t round32hi (const __int128_t arg) +{ + const int SHIFT = 96; + const int mshift = 96; + const __int128_t M = (~(__int128_t) 0) << mshift; + const __int128_t L = (~M) + 1; + const __int128_t L1 = ((__int128_t) L) >> 1; + const __int128_t Mlo = ((__int128_t) (~M)) >> 1; + __int128_t vv = arg & M; + + if ((arg & (L1)) && ((arg & Mlo) || (arg & L))) + vv += L; + + return (int32_t) (vv >> SHIFT); +} -- cgit v1.2.3
