The gccld program dies on the following assertion when linking main.s.bc and
libstdc++:

Linked in bytecode file
'/home/vadve/lattner/local/x86/llvm-gcc/bin/../lib/gcc/i686-pc-linux-gnu/3.4-llvm/../../../libstdc++.so'
gccld: /home/vadve/criswell/llvm/lib/VMCore/SymbolTable.cpp:93: void
llvm::SymbolTable::remove(llvm::Value*): Assertion `I != end() && "Trying to
remove a type that doesn't have a plane yet!"' failed.
g++: Internal error: Aborted (program gccld)

I'll try to reduce the bytecode file before attaching it.

Created an attachment (id=27) [details]
Assembly file that causes assertion

This is the small snipper of LLVM assembly, which, when compiled to bytecode
and linked to libstdc++, produces an assertion in gccld.

I'm working on this, but unfortunately libstdc++ is very very large.  :(

Note that this bug is also blocking llvm-llvm.

This bug is reproducable with llvm-link, so I'm changing the product/component.

Happy HAPPY day.  I was able to reduce libstdc++ down to:

---
target endian = little
target pointersize = 32
	%struct._Impl = type opaque
	"struct.std::locale::_Impl" = type { int }

%_ZNSt6locale10_S_classicE = global "struct.std::locale::_Impl"* null

implementation

void %foo(%struct._Impl* %tmp.6) {
	%tmp.6 = cast %struct._Impl* %tmp.6 to "struct.std::locale::_Impl"*
	ret void
}
---

And still be able to reproduce the problem.  _THIS_ I can do something with!  :)

Fixed, this was actually a problem in the SymbolTable class.  Your testcase now
links with libstdc++ as well as my reduced version.

Maybe llvm-llvm will link better now.  :)
