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/covariant6.C | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/testsuite/g++.dg/abi/covariant6.C (limited to 'gcc/testsuite/g++.dg/abi/covariant6.C') diff --git a/gcc/testsuite/g++.dg/abi/covariant6.C b/gcc/testsuite/g++.dg/abi/covariant6.C new file mode 100644 index 000000000..143b4ad36 --- /dev/null +++ b/gcc/testsuite/g++.dg/abi/covariant6.C @@ -0,0 +1,34 @@ +struct A +{ + virtual A* f(); +}; + +struct B: virtual A +{ + virtual A* f(); +}; + +struct C: B +{ + virtual C* f(); +}; + +C* C::f() { return 0; } + +// When we emit C::f, we should emit both thunks: one for B and one for A. +// { dg-final { scan-assembler "_ZTch0_v0_n16_N1C1fEv" { target { ilp32 && { ! { ia64-*-hpux* } } } } } } +// { dg-final { scan-assembler "_ZTch0_v0_n32_N1C1fEv" { target { lp64 || { ia64-*-hpux* } } } } } +// { dg-final { scan-assembler "_ZTcv0_n12_v0_n16_N1C1fEv" { target { ilp32 && { ! { ia64-*-hpux* } } } } } } +// { dg-final { scan-assembler "_ZTcv0_n24_v0_n32_N1C1fEv" { target { lp64 || { ia64-*-hpux* } } } } } + +struct D: B +{ + virtual void dummy (); + virtual D* f(); +}; + +void D::dummy() { } + +// When we emit the D vtable, it should refer to the thunk for B. +// { dg-final { scan-assembler "_ZTch0_v0_n16_N1D1fEv" { target { ilp32 && { ! { ia64-*-hpux* } } } } } } +// { dg-final { scan-assembler "_ZTch0_v0_n32_N1D1fEv" { target { lp64 || { ia64-*-hpux* } } } } } -- cgit v1.2.3
