Subject: [PATCH v2 0/9] objtool: warning improvements
Date: Wed, 12 Apr 2023 12:03:15 -0700 [thread overview]
Message-ID: <cover.1681325924.git.jpoimboe@kernel.org> (raw)
v2:
- keep --backtrace
- hard-code awk logic (don't use objdump-func script)
- add OBJTOOL_VERBOSE=1
- add WARN_INSN()
- several other improvements/fixes - best to review from scratch ;-)
Josh Poimboeuf (9):
scripts/objdump-func: Support multiple functions
objtool: Add WARN_INSN()
objtool: Limit unreachable warnings to once per function
objtool: Add symbol iteration helpers
objtool: Add verbose option for disassembling affected functions
objtool: Include backtrace in verbose mode
objtool: Remove superfluous dead_end_function() check
objtool: Detect missing __noreturn annotations
objtool: Ignore exc_double_fault() __noreturn warnings
