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.dg/Wstrict-aliasing-float-ptr-int-obj.c | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wstrict-aliasing-float-ptr-int-obj.c (limited to 'gcc/testsuite/gcc.dg/Wstrict-aliasing-float-ptr-int-obj.c') diff --git a/gcc/testsuite/gcc.dg/Wstrict-aliasing-float-ptr-int-obj.c b/gcc/testsuite/gcc.dg/Wstrict-aliasing-float-ptr-int-obj.c new file mode 100644 index 000000000..b90fb76c2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wstrict-aliasing-float-ptr-int-obj.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-options "-O -Wstrict-aliasing -fstrict-aliasing" } */ + +extern int flag; + +int foo() { + + int x; + int y = 9; + float* q; + float* r; + + if (flag) { + q = (float*) &x; /* { dg-message "initialized" "" { xfail *-*-* } } */ + } else { + q = (float*) &y; /* { dg-message "initialized" "" { xfail *-*-* } } */ + } + + *q = 1.0; /* { dg-warning "does break strict-aliasing" "" { xfail *-*-* } } */ + + return x; + +} -- cgit v1.2.3
