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/recip-6.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/recip-6.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/recip-6.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/recip-6.c b/gcc/testsuite/gcc.dg/tree-ssa/recip-6.c new file mode 100644 index 000000000..b3334fb86 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/recip-6.c @@ -0,0 +1,30 @@ +/* { dg-options "-O1 -funsafe-math-optimizations -fno-trapping-math -fdump-tree-recip" } */ +/* { dg-do compile } */ + +/* Test inserting in a block that does not contain a division. */ + +extern int f2(); + +double m, n, o; + +void f1(double y, double z, double w) +{ + double b, c, d, e, f; + + if (g ()) + b = 1 / y, c = z / y; + else + b = 3 / y, c = w / y; + + d = b / y; + e = c / y; + f = 1 / y; + + m = d; + n = e; + o = f; +} + +/* { dg-final { scan-tree-dump-times " / " 1 "recip" } } */ +/* { dg-final { cleanup-tree-dump "recip" } } */ + -- cgit v1.2.3
