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/pr47564.c | 42 +++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr47564.c (limited to 'gcc/testsuite/gcc.target/i386/pr47564.c') diff --git a/gcc/testsuite/gcc.target/i386/pr47564.c b/gcc/testsuite/gcc.target/i386/pr47564.c new file mode 100644 index 000000000..5d3f25d10 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr47564.c @@ -0,0 +1,42 @@ +/* PR target/47564 */ +/* { dg-do compile } */ +/* { dg-options "-O2 -msse2" } */ + +static inline unsigned long long +foo (const unsigned char *p) +{ + return 1; +} + +__attribute__ ((__target__ ("sse4"))) void +bar (unsigned long long *x, const void *b, long long m) +{ + const unsigned char *p = (const unsigned char *) b; + const unsigned char *e = p + m; + unsigned int l = *x; + unsigned long long n = l; + + if ((e - p) >= 8192) + { + while ((e - p) >= 128) + { + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + } + } + + while ((e - p) >= 16) + { + n = __builtin_ia32_crc32di (n, foo (p)); + n = __builtin_ia32_crc32di (n, foo (p)); + } + l = n; + *x = l; +} -- cgit v1.2.3
