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/vrp19.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/vrp19.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/vrp19.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/vrp19.c b/gcc/testsuite/gcc.dg/tree-ssa/vrp19.c new file mode 100644 index 000000000..e4c884a85 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/vrp19.c @@ -0,0 +1,27 @@ +/* { dg-do compile } */ +/* { dg-options "-fwrapv -O1 -ftree-vrp -fdump-tree-vrp1" } */ + +#include +extern void abort (); +extern void exit (int); + +int f (int a) { + if (a != INT_MIN) { + a = a > 0 ? a : -a; + if (a < 0) + return 1; + } + return 0; +} + +int g (int b) { + if (b != INT_MIN) { + b = b > 0 ? b : -b; + if (b >= 0) + return 0; + } + return 1; +} +/* { dg-final { scan-tree-dump "Folding predicate a_. < 0 to 0" "vrp1" } } */ +/* { dg-final { scan-tree-dump "Folding predicate b_. >= 0 to 1" "vrp1" } } */ +/* { dg-final { cleanup-tree-dump "vrp1" } } */ -- cgit v1.2.3
