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/20040204-1.c | 37 ++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c b/gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c new file mode 100644 index 000000000..45e44a1b2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20040204-1.c @@ -0,0 +1,37 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-optimized" } */ + +extern void link_error (void); + +/* + test that a condition is propagated inside an if +*/ + +void test5 (int x) +{ + extern int foo (int); + if (x == 0) + foo (x); + else if (x == 0 ) + link_error (); +} + +void test55 (int x, int y) +{ + int u; + if (x == 5 && y) + { + u = x + 22; + if (u != 27) + link_error (); + } +} + +/* There should be not link_error calls, if there is any the + optimization has failed */ +/* ???
