In the old METHODs I'm converting on the pdd17pmc branch, a number of
them have a void return signature (now simply no return value), and use
void returns to bail out early on exceptional conditions. As in:
if (!foo)
return;
But, PCCMETHODs don't currently provide a way of handling explicit void
returns. An implicit void return (falling thorough to the end of the
method with no explicit return) jumps to the 'no_return:' label at the
end of the generated method. So, I've added a feature (in the branch) to
lib/Parrot/Pmc2c/PCCMETHOD.pm that parses a PCCRETURN with the signature
'void' and generates the same jump code as an implicit void return.
