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/loadpre15.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/loadpre15.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/loadpre15.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/loadpre15.c b/gcc/testsuite/gcc.dg/tree-ssa/loadpre15.c new file mode 100644 index 000000000..b04c7621b --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/loadpre15.c @@ -0,0 +1,19 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre-stats" } */ +typedef int type[2]; +int foo(type *a, int argc, int t) +{ + type c = {0, 1}; + int d, e; + + /* Should be able to eliminate the second load of *a along the main path. */ + d = (*a)[t]; + if (argc) + { + a = &c; + } + e = (*a)[t]; + return d + e; +} +/* { dg-final { scan-tree-dump-times "Eliminated: 1" 1 "pre"} } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ -- cgit v1.2.3
