[libcxx-commits] [PATCH] D69677: Correctly update isSignalFrame when unwinding the stack via dwarf.

[Eric Christopher via Phabricator via libcxx-commits]

echristo added a comment.

Outside of the code factoring which I haven't looked at I thought I'd link this:

https://www.airs.com/blog/archives/460

as the best description I've got for what cfi_signal_frame is supposed to be doing here - look for the bit with the augmentation value of 'S' in there for the description.

Sterling: Probably wouldn't hurt to describe this much more in the commit/patch message for future archaeologists.
