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/register-variables.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/register-variables.c (limited to 'gcc/testsuite/gcc.target/arm/register-variables.c') diff --git a/gcc/testsuite/gcc.target/arm/register-variables.c b/gcc/testsuite/gcc.target/arm/register-variables.c new file mode 100644 index 000000000..8c874b22e --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/register-variables.c @@ -0,0 +1,21 @@ +/* { dg-do run } */ +/* { dg-options "-O" } */ + +#include + +void __attribute__((noinline)) +bar(int a, int b) +{ + if (a != 43 || b != 42) + abort(); +} + +int main(void) +{ + register int r0 asm("r0") = 42; + register int r1 asm("r1") = 43; + asm volatile("": "+r" (r0), "+r" (r1)); + bar(r1, r0); + return 0; +} + -- cgit v1.2.3
