[PATCH] D98789: [PEI] add dwarf information for stack probe

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Generally, unlike the formats used on Windows etc., DWARF unwind isn't accurate in the prologue.  I mean, you could add separate unwind info for each relevant instruction, but that would be a lot of data, and we currently don't have any option to do that.

Given that, I'm not sure what you're trying to accomplish here.  I can't see how adding more .cfi_adjust_cfa_offset directives does anything useful.
