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/sh/sh2a-prefetch.c | 34 +++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/testsuite/gcc.target/sh/sh2a-prefetch.c (limited to 'gcc/testsuite/gcc.target/sh/sh2a-prefetch.c') diff --git a/gcc/testsuite/gcc.target/sh/sh2a-prefetch.c b/gcc/testsuite/gcc.target/sh/sh2a-prefetch.c new file mode 100644 index 000000000..e0c9a0d7d --- /dev/null +++ b/gcc/testsuite/gcc.target/sh/sh2a-prefetch.c @@ -0,0 +1,34 @@ +/* Testcase to check generation of a SH2A specific instruction PREF @Rm. */ +/* { dg-do assemble {target sh*-*-*}} */ +/* { dg-options "-O0" } */ +/* { dg-skip-if "" { "sh*-*-*" } "*" "-m2a -m2a-nofpu -m2a-single -m2a-single-only" } */ +/* { dg-final { scan-assembler "pref"} } */ + +void +opt (void) +{ + int *p, wk; + int data[100]; + + /* data prefetch , instructions hit the cache. */ + + __builtin_prefetch (&data[0], 0, 0); + __builtin_prefetch (&data[0], 0, 1); + __builtin_prefetch (&data[0], 0, 2); + __builtin_prefetch (&data[0], 0, 3); + __builtin_prefetch (&data[0], 1, 0); + __builtin_prefetch (&data[0], 1, 1); + __builtin_prefetch (&data[0], 1, 2); + __builtin_prefetch (&data[0], 1, 3); + + + for (p = &data[0]; p < &data[9]; p++) + { + if (*p > *(p + 1)) + { + wk = *p; + *p = *(p + 1); + *(p + 1) = wk; + } + } +} -- cgit v1.2.3
