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/old-style-asm-1.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/old-style-asm-1.c (limited to 'gcc/testsuite/gcc.dg/old-style-asm-1.c') diff --git a/gcc/testsuite/gcc.dg/old-style-asm-1.c b/gcc/testsuite/gcc.dg/old-style-asm-1.c new file mode 100644 index 000000000..8af007795 --- /dev/null +++ b/gcc/testsuite/gcc.dg/old-style-asm-1.c @@ -0,0 +1,23 @@ +/* PR inline-asm/8832 */ +/* { dg-do compile } */ +/* { dg-options "-O2 -dP" } */ + +/* Verify that GCC doesn't optimize + old style asm instructions. */ + +void foo(int v) +{ + if (v) + asm ("dummy1"); + + asm ("dummy2"); + + if (v) + asm ("dummy3"); +} + +/* The purpose of the test below is to check that there are two branches + in the generated code, supposedly corresponding to the if-statements. + It tries to check for jump_insn (set (pc) pattern, so that jump_insns + corresponding to return are not taken into account. */ +/* { dg-final { scan-assembler "jump_insn.*set \\(pc\\).*jump_insn.*set \\(pc\\)"} } */ -- cgit v1.2.3
