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/inherit/covariant7.C | 51 +++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 gcc/testsuite/g++.dg/inherit/covariant7.C (limited to 'gcc/testsuite/g++.dg/inherit/covariant7.C') diff --git a/gcc/testsuite/g++.dg/inherit/covariant7.C b/gcc/testsuite/g++.dg/inherit/covariant7.C new file mode 100644 index 000000000..4f0c7f7dd --- /dev/null +++ b/gcc/testsuite/g++.dg/inherit/covariant7.C @@ -0,0 +1,51 @@ +// { dg-do compile } +// { dg-prune-output "direct base" } +// { dg-options "-fdump-class-hierarchy" } + +// Copyright (C) 2002 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 27 Dec 2002 + +// We ICE'd + +struct c0 {}; + +struct c1 : virtual c0 +{ + virtual c0 &f2() volatile; +}; + +struct c2 +{ + int m; +}; + +struct c3 : virtual c0, virtual c1, c2 +{ + virtual c1 &f2() volatile; +}; + +struct c4 : virtual c3, virtual c0, virtual c1 +{ + int m; +}; + +struct c6 : c0, c3, c4 +{ + virtual c1 &f2() volatile; +}; + +// f2 appears four times in the c6 vtables: +// once in c1-in-c3-in-c6 - covariant, virtual base, uses c1 vcall offset and c0 vbase offset +// { dg-final { scan-tree-dump "24 .*c6::_ZTcv0_n16_v0_n12_NV2c62f2Ev" "class" { target ilp32 } } } +// { dg-final { scan-tree-dump "48 .*c6::_ZTcv0_n32_v0_n24_NV2c62f2Ev" "class" { target lp64 } } } +// once in c3-in-c6 - non-covariant, non-virtual base, calls f2 directly +// { dg-final { scan-tree-dump "28 .*c6::f2" "class" { target ilp32 } } } +// { dg-final { scan-tree-dump "56 .*c6::f2" "class" { target lp64 } } } +// once in c1-in-c3-in-c4-in-c6 - lost primary +// { dg-final { scan-tree-dump "80 .*0u" "class" { target ilp32 } } } +// { dg-final { scan-tree-dump "160 .*0u" "class" { target lp64 } } } +// once in c3-in-c4-in-c6 - c3 vcall offset +// { dg-final { scan-tree-dump "84 .*c6::_ZTv0_n16_NV2c62f2Ev" "class" { target ilp32 } } } +// { dg-final { scan-tree-dump "168 .*c6::_ZTv0_n32_NV2c62f2Ev" "class" { target lp64 } } } + +// { dg-final { cleanup-tree-dump "class" } } -- cgit v1.2.3
