Sean:

- PowerPC doesn’t work, and never will.
- Signals mostly work; should be ok as long as you aren’t doing anything too strange.
- System call coverage is gradually improving.
- Obj-C GC is unchanged.
- –db-attach=yes won’t work.
- Tools other than Memcheck: they all work except for Helgrind and DRD.

Nicholas, thanks for the quick reply. I’ll give it a try. Is Greg’s list of stuff that does not work still current? He lists:

- PowerPC code
- Signals
- Many system calls
- Objective-C garbage collection
- –db-attach=yes
- Tools other than memcheck

And what about 64 bit apps? Thanks.

Sean, probably not, although I haven’t tried. Greg Parker listed that as a limitation of the original patch and I’m not aware of any changes that would have affected that. You could try it yourself and see how it goes.

Does valgrind work with the Objective-C Garbage Collected apps yet?

APE (which not many people are running on Leopard) will also break valgrind if you run it – the injection into the process actually seems to work (at least for a little while), but it tries to read thread-local data which doesn’t work. I don’t really think that’s a valgrind bug, though.
