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/g++.old-deja/g++.other/warn4.C | 68 ++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.other/warn4.C (limited to 'gcc/testsuite/g++.old-deja/g++.other/warn4.C') diff --git a/gcc/testsuite/g++.old-deja/g++.other/warn4.C b/gcc/testsuite/g++.old-deja/g++.other/warn4.C new file mode 100644 index 000000000..7973c75d0 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.other/warn4.C @@ -0,0 +1,68 @@ +// { dg-do assemble } +// { dg-options "-Wsign-conversion" } + +// Copyright (C) 1999 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 21 Nov 1999 + +// make sure we only warn on assigning a negative (signed) value +// to an unsigned type, and don't warn just if the unsigned value +// happens to have the top bit set. + +typedef unsigned U; + +void fn (unsigned); + +void fu () +{ + unsigned s1 = -1u; + unsigned s2(-1u); + unsigned volatile s3 = -1u; + unsigned const s4 = -1u; + unsigned const &s5(-1u); + s1 = -1u; + fn (-1u); +} + +void fU () +{ + U s1 = -1u; + U s2(-1u); + U volatile s3 = -1u; + U const s4 = -1u; + U const &s5(-1u); + s1 = -1u; + fn (-1u); +} + +void fs () +{ + unsigned s1 = -1; // { dg-warning "" } initialization + unsigned s2(-1); // { dg-warning "" } initialization + unsigned volatile s3 = -1;// { dg-warning "" } initialization + unsigned const s4 = -1; // { dg-warning "" } initialization + unsigned const &s5(-1); // { dg-warning "" } initialization + s1 = -1; // { dg-warning "" } assignment + fn (-1); // { dg-warning "" } passing +} + +void fss () +{ + unsigned s1 = -(-1); + unsigned s2(-(-1)); + unsigned volatile s3 = -(-1); + unsigned const s4 = -(-1); + unsigned const &s5(-(-1)); + s1 = -(-1); + fn (-(-1)); +} + +void fsz () +{ + unsigned s1 = -0; + unsigned s2(-0); + unsigned volatile s3 = -0; + unsigned const s4 = -0; + unsigned const &s5(-0); + s1 = -0; + fn (-0); +} -- cgit v1.2.3
