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/arm/neon-cond-1.c | 31 ++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/neon-cond-1.c (limited to 'gcc/testsuite/gcc.target/arm/neon-cond-1.c') diff --git a/gcc/testsuite/gcc.target/arm/neon-cond-1.c b/gcc/testsuite/gcc.target/arm/neon-cond-1.c new file mode 100644 index 000000000..a67625014 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/neon-cond-1.c @@ -0,0 +1,31 @@ +/* { dg-do run } */ +/* { dg-require-effective-target arm_neon_hw } */ +/* { dg-options "-O2" } */ +/* { dg-add-options arm_neon } */ +/* Check that the arm_final_prescan_insn ccfsm code does not try to + * conditionally execute NEON instructions. */ +#include +#include + +int __attribute__((noinline)) +foo(uint32x2_t a, uint32_t *p, uint32_t *q) +{ + if (p != q) + /* This vst1 instruction could be conditional, except that NEON + instructions are never conditional in ARM mode. */ + vst1_u32(p, a); + return 0; +} + +int +main() +{ + uint32x2_t v; + uint32_t a[2] = {1, 42}; + v = vld1_u32(a); + v = vadd_u32(v, v); + foo(v, a, a); + if (a[0] != 1 || a[1] != 42) + abort(); + exit(0); +} -- cgit v1.2.3
