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.misc-tests/i386-pf-none-1.c | 29 +++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gcc.misc-tests/i386-pf-none-1.c (limited to 'gcc/testsuite/gcc.misc-tests/i386-pf-none-1.c') diff --git a/gcc/testsuite/gcc.misc-tests/i386-pf-none-1.c b/gcc/testsuite/gcc.misc-tests/i386-pf-none-1.c new file mode 100644 index 000000000..d87a2100d --- /dev/null +++ b/gcc/testsuite/gcc.misc-tests/i386-pf-none-1.c @@ -0,0 +1,29 @@ +/* Test that data prefetch instructions are not generated for i386 variants + that do not support those instructions. */ + +/* { dg-do compile { target i?86-*-* x86_64-*-* } } */ +/* { dg-require-effective-target ilp32 } */ + +extern void exit (int); + +char *msg = "howdy there"; + +void foo (char *p) +{ + __builtin_prefetch (p, 0, 0); + __builtin_prefetch (p, 0, 1); + __builtin_prefetch (p, 0, 2); + __builtin_prefetch (p, 0, 3); + __builtin_prefetch (p, 1, 0); + __builtin_prefetch (p, 1, 1); + __builtin_prefetch (p, 1, 2); + __builtin_prefetch (p, 1, 3); +} + +int main () +{ + foo (msg); + exit (0); +} + +/* { dg-final { scan-assembler-not "fetch" } } */ -- cgit v1.2.3
