[PATCH] D96004: [AArch64] Stack probing for function prologues

[Oskar Wirga via Phabricator via llvm-commits]

oskarwirga added a comment.

I've spent some time myself working rebasing this stack and getting it green. Currently running into a runtime crash in libunwind where parseFDEInstructions is being called over and over and exhausting stack memory. Current best guess is that perhaps the stack probing is messing up the call frame information in such a way that causes a loop in the libunwind. If anyone has any suggestions of where to look or how to debug this I would appreciate it :)
