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-8-O0.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/uninit-8-O0.c (limited to 'gcc/testsuite/gcc.dg/uninit-8-O0.c') diff --git a/gcc/testsuite/gcc.dg/uninit-8-O0.c b/gcc/testsuite/gcc.dg/uninit-8-O0.c new file mode 100644 index 000000000..b386896c7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/uninit-8-O0.c @@ -0,0 +1,32 @@ +/* Uninitialized variable warning tests... + Inspired by part of optabs.c:expand_binop. + May be the same as uninit-1.c. */ + +/* { dg-do compile } */ +/* { dg-options "-Wuninitialized" } */ + +#include + +void +add_bignums (int *out, int *x, int *y) +{ + int p, sum; + int carry; /* { dg-bogus "carry" "uninitialized variable warning" } */ + + p = 0; + for (; *x; x++, y++, out++, p++) + { + if (p) + sum = *x + *y + carry; + else + sum = *x + *y; + + if (sum < 0) + { + carry = 1; + sum -= INT_MAX; + } + else + carry = 0; + } +} -- cgit v1.2.3
