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/bitfld-2.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/bitfld-2.c (limited to 'gcc/testsuite/gcc.dg/bitfld-2.c') diff --git a/gcc/testsuite/gcc.dg/bitfld-2.c b/gcc/testsuite/gcc.dg/bitfld-2.c new file mode 100644 index 000000000..b61fec608 --- /dev/null +++ b/gcc/testsuite/gcc.dg/bitfld-2.c @@ -0,0 +1,23 @@ +/* Copyright (C) 2002 Free Software Foundation, Inc. + + Tests we warn about overly-large assignments to bitfields. + + Source: Neil Booth, 28 Jan 2002. +*/ + +struct bf +{ + unsigned int a: 2; + int b: 2; +}; + +struct bf p = {4, 0}; /* { dg-warning "truncated" "" } */ +struct bf q = {0, 2}; /* { dg-warning "overflow" "" } */ +struct bf r = {3, -2}; /* { dg-bogus "(truncated|overflow)" } */ + +void foo () +{ + p.a = 4, p.b = 0; /* { dg-warning "truncated" "" } */ + q.a = 0, q.b = 2; /* { dg-warning "overflow" "" } */ + r.a = 3, r.b = -2; /* { dg-bogus "(truncated|overflow)" } */ +} -- cgit v1.2.3
