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/ssa-pre-12.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-12.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-12.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-12.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-12.c new file mode 100644 index 000000000..fd80e3d8d --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-12.c @@ -0,0 +1,27 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre-stats" } */ +double cos (double) __attribute__ ((const)); +double sin (double) __attribute__ ((const)); +double f(double a) +{ + double b; + double c,d; + double (*fp) (double) __attribute__ ((const)); + /* Fully redundant call, but we need a phi node to merge the results. */ + if (a < 2.0) + { + fp = sin; + c = fp (a); + } + else + { + c = 1.0; + fp = cos; + c = fp (a); + } + d = fp (a); + return d + c; +} + +/* { dg-final { scan-tree-dump-times "Eliminated: 1" 1 "pre"} } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ -- cgit v1.2.3
