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/powerpc/pr53199.c | 50 ++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/pr53199.c (limited to 'gcc/testsuite/gcc.target/powerpc/pr53199.c') diff --git a/gcc/testsuite/gcc.target/powerpc/pr53199.c b/gcc/testsuite/gcc.target/powerpc/pr53199.c new file mode 100644 index 000000000..89a0cad06 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/pr53199.c @@ -0,0 +1,50 @@ +/* { dg-do compile { target { powerpc*-*-* } } } */ +/* { dg-skip-if "" { powerpc*-*-darwin* } { "*" } { "" } } */ +/* { dg-options "-O2 -mcpu=power6 -mavoid-indexed-addresses" } */ +/* { dg-final { scan-assembler-times "lwbrx" 6 } } */ +/* { dg-final { scan-assembler-times "stwbrx" 6 } } */ + +/* PR 51399: bswap gets an error if -mavoid-indexed-addresses was used in + creating the two lwbrx instructions. */ + +long long +load64_reverse_1 (long long *p) +{ + return __builtin_bswap64 (*p); +} + +long long +load64_reverse_2 (long long *p) +{ + return __builtin_bswap64 (p[1]); +} + +long long +load64_reverse_3 (long long *p, int i) +{ + return __builtin_bswap64 (p[i]); +} + +void +store64_reverse_1 (long long *p, long long x) +{ + *p = __builtin_bswap64 (x); +} + +void +store64_reverse_2 (long long *p, long long x) +{ + p[1] = __builtin_bswap64 (x); +} + +void +store64_reverse_3 (long long *p, long long x, int i) +{ + p[i] = __builtin_bswap64 (x); +} + +long long +reg_reverse (long long x) +{ + return __builtin_bswap64 (x); +} -- cgit v1.2.3
