Subject: c++/9459: typeof in return type specification of template not supported
Date: Mon, 27 Jan 2003 16:36:00 -0000 [thread overview]
Message-ID: <20030127162730.26985.qmail@sources.redhat.com> (raw)

>Organization:
>Environment:
all versions of gcc until present 3.4 CVS
>Description:
This has never worked in C++ (2.95 ICEs, more recent version
just fail, see below):
----------------------------
void foo (int) {}
void foo (double) {}
template <typename C>
typeof(foo(1))
bar () { return foo(1); }
----------------------------
g/a> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c bug34-4.cc
bug34-4.cc:7: sorry, unimplemented: `typeof_type' not supported by
dump_type_prefix
bug34-4.cc:7: sorry, unimplemented: `typeof_type' not supported by
dump_type_suffix
While typeof is a gcc extension, it is a very valuable
one, and in this particular instance, cannot even be
replaced by template magic, as far as I know...
