[PATCH] D158655: [libunwind][AIX] Fix problem with stepping up from a leaf function when unwinding started in a signal handler

[Xing Xue via Phabricator via llvm-commits]

xingxue added inline comments.


================
Comment at: libunwind/src/UnwindCursor.hpp:2324
   // lastStack points to the stack frame of the next routine up.
   pint_t lastStack = *(reinterpret_cast<pint_t *>(registers.getSP()));

> @xingxue, is a change coming for this? I think this also falls into "cases that arise when unwinding past a signal handler".
Yes, @stephenpeckham has something that deals with it. I will refresh once that is finalized.
