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/ipa-split-5.c | 37 +++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ipa-split-5.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ipa-split-5.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ipa-split-5.c b/gcc/testsuite/gcc.dg/tree-ssa/ipa-split-5.c new file mode 100644 index 000000000..bf0714902 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ipa-split-5.c @@ -0,0 +1,37 @@ +/* { dg-do compile } */ +/* { dg-options "-O3 -fdump-tree-fnsplit -fdump-tree-optimized" } */ + +struct a {int a,b;}; +struct a make_me_big (int a); +struct a split_me (int a) +{ + struct a retval; + if (__builtin_expect (a!=0,1)) + { + retval.a = 0; + retval.b = 0; + return retval; + } + else + { + struct a retval = make_me_big (a); + retval = make_me_big (a); + retval = make_me_big (a); + retval = make_me_big (a); + retval = make_me_big (a); + retval = make_me_big (a); + return retval; + } +} +int val; +test() +{ + split_me (val); + split_me (val); + split_me (val); + split_me (val); +} +/* { dg-final { scan-tree-dump-times "Splitting function" 1 "fnsplit"} } */ +/* { dg-final { cleanup-tree-dump "fnsplit" } } */ +/* { dg-final { scan-tree-dump "part" "optimized"} } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
