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/20030807-3.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030807-3.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030807-3.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030807-3.c b/gcc/testsuite/gcc.dg/tree-ssa/20030807-3.c new file mode 100644 index 000000000..9a3c23163 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030807-3.c @@ -0,0 +1,27 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-dom2" } */ + +typedef unsigned int cppchar_t; +cppchar_t +cpp_parse_escape (pstr, limit, wide) + const unsigned char **pstr; + const unsigned char *limit; + int wide; +{ + cppchar_t i = 0; + int overflow = 0; + cppchar_t mask = ~0; + + while (*pstr < limit) + { + overflow |= i ^ (i << 4 >> 4); + i = oof (); + } + if (overflow | (i != (i & mask))) + foo(); +} + +/* There should be precisely three IF statements.
