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/shift_mask.c | 31 ++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/shift_mask.c (limited to 'gcc/testsuite/gcc.target/i386/shift_mask.c') diff --git a/gcc/testsuite/gcc.target/i386/shift_mask.c b/gcc/testsuite/gcc.target/i386/shift_mask.c new file mode 100644 index 000000000..29c84bd1d --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/shift_mask.c @@ -0,0 +1,31 @@ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ + +int test_sal (int a, int c) +{ + return a << (c & 0x1f); +} + +int test_sar (int a, int c) +{ + return a >> (c & 0x1f); +} + +unsigned int test_shr (unsigned int a, int c) +{ + return a >> (c & 0x1f); +} + +unsigned int test_rol (unsigned int a, int c) +{ + int z = c & 0x1f; + return (a << z) | (a >> (32 - z)); +} + +unsigned int test_ror (unsigned int a, int c) +{ + int z = c & 0x1f; + return (a >> z) | (a << (32 - z)); +} + +/* { dg-final { scan-assembler-not "and" } } */ -- cgit v1.2.3
