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++.law/arg7.C | 33 +++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.law/arg7.C (limited to 'gcc/testsuite/g++.old-deja/g++.law/arg7.C') diff --git a/gcc/testsuite/g++.old-deja/g++.law/arg7.C b/gcc/testsuite/g++.old-deja/g++.law/arg7.C new file mode 100644 index 000000000..a3ccab92b --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.law/arg7.C @@ -0,0 +1,33 @@ +// { dg-do run } +// GROUPS passed arg-matching +// arg-matching file +// Message-Id: <9305041759.AA04913@malachite.bbn.com> +// From: Dan Franklin +// Subject: overloaded function resolved incorrectly +// Date: Tue, 4 May 93 13:59:18 EDT + +#include + +// Given the following overloaded function definitions + +int ovf(unsigned long, short, short) { printf ("PASS\n"); return 0; } +int ovf( int, short, unsigned long) { printf ("FAIL\n"); return 1; } + +// and the call +// +// ovf(unsigned long, unsigned int, unsigned int) +// +// it seems to me (and to cfront) that this should resolve to ovf #1 above, +// but g++ resolves it to ovf #2.
