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.dg/tree-ssa/asm-3.c | 36 +++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/asm-3.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/asm-3.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/asm-3.c b/gcc/testsuite/gcc.dg/tree-ssa/asm-3.c new file mode 100644 index 000000000..5ed282e49 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/asm-3.c @@ -0,0 +1,36 @@ +/* PR 17739 */ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-optimized" } */ + +#ifdef __hppa__ +#define REGISTER "1" +#else +#ifdef __moxie__ +#define REGISTER "8" +#else +#define REGISTER "0" +#endif +#endif + +static inline int source(void) +{ + register int hardreg __asm__(REGISTER); + asm("" : "=r"(hardreg)); + return hardreg; +} + +void test(void) +{ + int t = source(); + foo(t); + bar(t); +} + +/* Hardreg should appear exactly 3 times -- declaration, asm stmt, + and copy out. */ +/* { dg-final { scan-tree-dump-times "hardreg" 3 "optimized" } } */ + +/* In particular, hardreg should *not* appear in the call to bar. */ +/* { dg-final { scan-tree-dump-times "bar \[(\]t_.\[)\]" 1 "optimized" } } */ + +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
