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/mips/r10k-cache-barrier-8.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/gcc.target/mips/r10k-cache-barrier-8.c (limited to 'gcc/testsuite/gcc.target/mips/r10k-cache-barrier-8.c') diff --git a/gcc/testsuite/gcc.target/mips/r10k-cache-barrier-8.c b/gcc/testsuite/gcc.target/mips/r10k-cache-barrier-8.c new file mode 100644 index 000000000..394bf486f --- /dev/null +++ b/gcc/testsuite/gcc.target/mips/r10k-cache-barrier-8.c @@ -0,0 +1,15 @@ +/* { dg-options "-O2 -mr10k-cache-barrier=store -G8" } */ + +/* Test that in-range stores to components of static objects + do not get an unnecessary cache barrier. */ + +struct { struct { char i[4]; } a; struct { char j[4]; } b; } s; + +NOMIPS16 void +foo (int sel) +{ + s.a.i[0] = 1; + s.b.j[3] = 100; +} + +/* { dg-final { scan-assembler-not "\tcache\t" } } */ -- cgit v1.2.3
