[JIT changes]
I just finished tracking down the source of a couple of JIT test failures on PPC--due to recent changes but only indirectly related, and pointing out things which needed fixing anyway (float register preservation issues). I'll send it in tomorrow after I've had a chance to clean it up and add some comments.
Please make sure to get a recent CVS copy and try to prepare the patch during my night ;) I've changed the PPC float register allocation yesterday, because it did look bogus - i.e. the non-volatile FPRs were allocated but not saved. That should be fixed.
While you're investigating PPC JIT: JIT debugging via stabs doesn't work at all here. I get around the gdb message (missing data segment) by inserting ".data\n.text\n" in the stabs file, but that's all. After this change and regenerating "file.o" I can load it with "add-symbol-file file.o" without any complaint, but the access to the memory region the jitted code occupies is not allowed, disassemble doesn't work ...
