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/conversion/ptrmem4.C | 43 +++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/g++.dg/conversion/ptrmem4.C (limited to 'gcc/testsuite/g++.dg/conversion/ptrmem4.C') diff --git a/gcc/testsuite/g++.dg/conversion/ptrmem4.C b/gcc/testsuite/g++.dg/conversion/ptrmem4.C new file mode 100644 index 000000000..fd260df64 --- /dev/null +++ b/gcc/testsuite/g++.dg/conversion/ptrmem4.C @@ -0,0 +1,43 @@ +// Copyright (C) 2007 Free Software Foundation +// Contributed by Ollie Wild +// { dg-do compile } + +// Assorted pointer to data member c-style cast tests. + +struct X {}; +struct A { int x; }; +struct B : A { int x; }; +struct P : A { int x; }; +struct V { int x; }; +struct D : B, virtual V, private P { int x; }; + +// Accessible, non-virtual, non-ambiguous base clas. +int B::*p1 = (int B::*)&D::x; +int D::*p2 = (int D::*)&B::x; + +// Virtual base class. +int V::*p3 = (int V::*)&D::x; // { dg-error "" } +int D::*p4 = (int D::*)&V::x; // { dg-error "" } + +// Inaccessible base class. +int P::*p5 = (int P::*)&D::x; +int D::*p6 = (int D::*)&P::x; + +// Ambiguous base class. +int A::*p7 = (int A::*)&D::x; // { dg-error "" } +int D::*p8 = (int D::*)&A::x; // { dg-error "" } + +// Valid conversions which increase cv-qualification. +const int B::*p9 = (const int B::*)&D::x; +const int D::*p10 = (const int D::*)&B::x; + +// Valid conversions which decrease cv-qualification. +int B::*p11 = (int B::*)p10; +int D::*p12 = (int D::*)p9; + +// Attempts to change member type allowed via reinterpret_cast. +float B::*p13 = (float B::*)&D::x; +float D::*p14 = (float D::*)&B::x; + +// Conversion via unrelated classes allwed via reinterpret_cast. +int X::*p15 = (int X::*)&D::x; -- cgit v1.2.3
