[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 ;) --- dmd/expression.c | 47 +++++++++++++++++++++++++++++++++++++++++------ 1 files changed, 41 insertions(+), 6 deletions(-)
