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/tailrecursion-4.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/tailrecursion-4.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/tailrecursion-4.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/tailrecursion-4.c b/gcc/testsuite/gcc.dg/tree-ssa/tailrecursion-4.c new file mode 100644 index 000000000..d89739f3a --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/tailrecursion-4.c @@ -0,0 +1,18 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -foptimize-sibling-calls -fdump-tree-tailr-details" } */ +int +t(int a) +{ + int r; + if (a&1) + r = t(a-1); + else if (a) + r = t(a-2); + else + return 0; + if (r) + r=r; + return r; +} +/* { dg-final { scan-tree-dump-times "Eliminated tail recursion" 2 "tailr1"} } */ +/* { dg-final { cleanup-tree-dump "tailr\[1-2\]" } } */ -- cgit v1.2.3
