[WIP] Merge DMD r251: bugzilla 111 (appending a dchar to a char[])
This patch needs some work in the code generation, because of the runtime
changes (functions "_d_arrayappendcd" and "_d_arrayappendwd" are added).
This doesn't affect existing code though, it just makes with patch
a little useless, because something like this:
char [] s;
s ~= '\u6211';
That failed to compile with a nice error message previously to this
change, now fails with and ugly error message (a failed assertion).
Apparently there is a regression introduced by this patch too, when
compiling Dil I get this assertion message:
ldc: /home/luca/tesis/ldc/gen/statements.cpp:132: virtual void ReturnStatement::toIR(IRState*): Assertion `p->topfunc()->getReturnType() == llvm::Type::getVoidTy(gIR->context())' failed.
0 ldc 0x08a91628
Thank god we have bisecting capabilities in VCSs now ;)
