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++.dg/abi/covariant4.C | 46 +++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/g++.dg/abi/covariant4.C (limited to 'gcc/testsuite/g++.dg/abi/covariant4.C') diff --git a/gcc/testsuite/g++.dg/abi/covariant4.C b/gcc/testsuite/g++.dg/abi/covariant4.C new file mode 100644 index 000000000..942b1686e --- /dev/null +++ b/gcc/testsuite/g++.dg/abi/covariant4.C @@ -0,0 +1,46 @@ +// { dg-do run } + +// Copyright (C) 2005 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 11 Feb 2005 + +// Origin: bredelin@ucla.edu +// Bug 19891: Incorrect covariant vtables + +struct Model { + bool full_tree; + virtual Model* clone() const =0; + virtual const char *name() const =0; + virtual ~Model() {} +}; + +struct R: virtual public Model { + virtual R* clone() const =0; +}; +struct A: virtual public Model { + virtual A* clone() const=0; +}; +struct RA: public R, public A { + virtual RA* clone() const=0; +}; + +static const char *string = "EQU"; + +struct EQU: public RA { + virtual EQU* clone() const {return new EQU(*this);} + const char *name() const {return string;} +}; + +int main() { + Model* M1 = new EQU(); + Model* M2 = M1->clone(); + Model* M3 = M2->clone(); + + if (M1->name () != string) + return 1; + if (M2->name () != string) + return 2; + if (M3->name () != string) + return 3; + + return 0; +} -- cgit v1.2.3
