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/thunk1.C | 41 +++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/g++.dg/inherit/thunk1.C (limited to 'gcc/testsuite/g++.dg/inherit/thunk1.C') diff --git a/gcc/testsuite/g++.dg/inherit/thunk1.C b/gcc/testsuite/g++.dg/inherit/thunk1.C new file mode 100644 index 000000000..3bbd05069 --- /dev/null +++ b/gcc/testsuite/g++.dg/inherit/thunk1.C @@ -0,0 +1,41 @@ +// { dg-do run { target i?86-*-* x86_64-*-* s390*-*-* alpha*-*-* ia64-*-* sparc*-*-* } } + +#include + +extern "C" void abort (); + +struct A { + virtual void f (int, ...) {} + int i; +}; + +struct B : virtual public A { +}; + +struct C : public B { + C (); + virtual void f (int, ...); +}; + +extern C* cp; + +C::C () { cp = this; } + +void C::f (int i, ...) { + if (this != cp) + abort (); + va_list ap; + if (i != 3) + abort (); + va_start (ap, i); + if (va_arg (ap, int) != 7) + abort (); + va_end (ap); +} + +C* cp = new C; + +int main () +{ + cp->f (3, 7); +} -- cgit v1.2.3
