Subject: [PATCH 0/6] objtool: AUTOFDO fixes + alias improvements
Date: Thu, 20 Nov 2025 12:52:14 -0800 [thread overview]
Message-ID: <cover.1763671318.git.jpoimboe@kernel.org> (raw)
For tip/objtool/core.
- Patches 1 and 2 fix some issues which were found when testing with
AutoFDO .cold functions.
- Patches 3-5 make improvements to the handling of symbol aliases.
- Patch 6 uses the alias infrastructure to simplify the .cold
parent/child correlation code.
Josh Poimboeuf (6):
objtool: Support Clang AUTOFDO .cold functions
objtool: Fix .cold function detection for duplicate symbols
objtool: Don't alias undefined symbols
objtool: Return canonical symbol when aliases exist in symbol finding
helpers
objtool: Skip non-canonical aliased symbols in add_jump_table_alts()
objtool: Remove second pass of .cold function correlation
