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/Wstrict-overflow-15.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wstrict-overflow-15.c (limited to 'gcc/testsuite/gcc.dg/Wstrict-overflow-15.c') diff --git a/gcc/testsuite/gcc.dg/Wstrict-overflow-15.c b/gcc/testsuite/gcc.dg/Wstrict-overflow-15.c new file mode 100644 index 000000000..d1627d2f4 --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wstrict-overflow-15.c @@ -0,0 +1,15 @@ +/* { dg-do compile } */ +/* { dg-options "-fstrict-overflow -O2 -Wstrict-overflow=4" } */ + +/* Source: Ian Lance Taylor. */ + +int +foo (int j) +{ + int i; + int sum = 0; + + for (i = 1; i < j; i += i) + sum += __builtin_abs (i); /* { dg-warning "assuming signed overflow does not occur" "" } */ + return sum; +} -- cgit v1.2.3
