Subject: [PATCH v3 0/2] Fix reverse nexting over recursions
Date: Wed, 31 Aug 2022 14:07:26 +0200 [thread overview]
Message-ID: <20220831120727.2742360-1-blarsen@redhat.com> (raw)
This patch series fixes gdb record/16678, GDB being unable to
reverse-next over a recursive function. However, the simple way to fix
it hit a snag when I discovered that the amd64 epilogue unwinder would
give a different frame id than the dwarf2 unwinder would in the rest of
the function. This patch series first change this discrepancy, then
fixes the bug.
Changelog for v3:
* fix some comments on the amd64_epilogue_unwinder
* fix style for the step-reverse test
Changelog for v2:
* Implemented Pedro Alves's suggestion to simplify the fix
* Added the first patch to fix a regression that the simple fix
would introduce.
