--- Comment #7 from Julian Seward <jsew...@acm.org> --- Thanks for the testing and review. > + For s390, the unwound registers are: R11(FP) R14(LR) R15(SP) F0 F2 F4 … > This doesn't match the current implementation, right? That's correct. The comment is out of date. I'll fix it. > In fact it seems that F0-F7 are unwound, although F0, F2, and F4 are > probably sufficient (I hope). I at first implemented only F0, F2 and F4, but then I thought it would be worth checking for "summarisation failures" (failures to represent the unwind info in V's internal structures) when reading all the unwind data for libc/libpthread/whatever when starting a hello-world program. From that it was obvious that the compiler really does use all of F0-F7 at least once. So I decided to do them all. -- You are receiving this mail because: You are watching all bug changes.
