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/uninit-16.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/uninit-16.c (limited to 'gcc/testsuite/gcc.dg/uninit-16.c') diff --git a/gcc/testsuite/gcc.dg/uninit-16.c b/gcc/testsuite/gcc.dg/uninit-16.c new file mode 100644 index 000000000..e039f7026 --- /dev/null +++ b/gcc/testsuite/gcc.dg/uninit-16.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -Wuninitialized" } */ + +int foo, bar; + +static +void decode_reloc(int reloc, int *is_alt) +{ + if (reloc >= 20) + *is_alt = 1; + else if (reloc >= 10) + *is_alt = 0; +} + +void testfunc() +{ + int alt_reloc; + + decode_reloc(foo, &alt_reloc); + + if (alt_reloc) /* { dg-warning "may be used uninitialized" } */ + bar = 42; +} -- cgit v1.2.3
