Re: [perl #46179] [TODO] Remove GC code depending upon -D40 before parrot 1.0

The PMC and STRING registers obviously need to be nulled out for GC to avoid false positives. Do we need to clear the values of the INT and NUM registers too? If so, what values do we want them to have? Should we still use special flag values for -D40? There's a bit more history of this in [perl #38978] and [perl #39244] (and some other old tickets too, but those are enough to give the idea). The problem was that, on some compilers in some situations, the I and N registered ended up as 0 even if they weren't explicitly initialized, and various bits in the test suite worked accidentally because of that. (There used to be conditional compilation mixed in there as well, just to make it even more confusing.) Such bugs have long since been eradicated in the test suite, and nothing developed in the past couple of years could rely on accidental initialization. None of which answers your question. The original intent was that the registers are not to be initialized, which would mean deleting the second branch (with the 888's) but leaving the -D40 branch as a possible debugging tool. -- Andy Dougherty dough...@lafayette.edu
Re: [perl #55308] [TODO] [MMD] add_sub sanely adds MultiSub PMCs to a namespace

However, the change I'm committing is a little naive in that a subsequent call to add_sub will overwrite any existing MultiSub. Instead, adding a MultiSub to a namespace symbol that already contains a MultiSub should probably merge them together. pmichaud: Any updates on the status of this? It probably needs a Parrot architect to design/decide what should really happen here. I wasn't planning to take it any further than I already have. Perhaps this RT ticket needs to be moved to Trac.
