[PATCH v3 0/4] Fix 'faddr2line' for LLVM arm64 builds

From: Will Deacon
Date: Fri Jul 28 2023 - 07:34:27 EST


Hi all,

Here's version three of my faddr2line fixes previously posted here:

v1: https://lore.kernel.org/r/20230724174517.15736-1-will@xxxxxxxxxx
v2: https://lore.kernel.org/r/20230725211157.17031-1-will@xxxxxxxxxx

Changes since v2 include:
* Brought back the (unchanged) patch introducing LLVM=1 so that all
the patches are in one place and don't end up conflicting with each
other.
* Added a new patch to drop the strict "FUNC" symbol type match in
the outer loop

Cheers,

Will
