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/g++.dg/uninit-pred-loop-1_b.cc | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/g++.dg/uninit-pred-loop-1_b.cc (limited to 'gcc/testsuite/g++.dg/uninit-pred-loop-1_b.cc') diff --git a/gcc/testsuite/g++.dg/uninit-pred-loop-1_b.cc b/gcc/testsuite/g++.dg/uninit-pred-loop-1_b.cc new file mode 100644 index 000000000..e4ef3d22c --- /dev/null +++ b/gcc/testsuite/g++.dg/uninit-pred-loop-1_b.cc @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-options "-Wuninitialized -O2" } */ + +extern int bar(); +int foo(int n) +{ + for (;;) { + int err = ({int _err; + for (int i = 0; i < n; ++i) { + _err = 17; + _err = bar(); + } + _err; + }); /* { dg-warning "uninitialized" "warn on _err" } */ + + if (err == 0) return 17; + } + + return 18; +} + -- cgit v1.2.3
