From b18b851ba85a5855cb53865fcff3cd2c17b44b0b Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 2 Aug 2021 14:03:07 -0700 Subject: scripts/recordmcount.pl: Remove check_objcopy() and $can_use_local When building ARCH=riscv allmodconfig with llvm-objcopy, the objcopy version warning from this script appears: WARNING: could not find objcopy version or version is less than 2.17. Local function references are disabled. The check_objcopy() function in scripts/recordmcount.pl is set up to parse GNU objcopy's version string, not llvm-objcopy's, which triggers the warning. Commit 799c43415442 ("kbuild: thin archives make default for all archs") made binutils 2.20 mandatory and commit ba64beb17493 ("kbuild: check the minimum assembler version in Kconfig") enforces this at configuration time so just remove check_objcopy() and $can_use_local instead, assuming --globalize-symbol is always available. llvm-objcopy has supported --globalize-symbol since LLVM 7.0.0 in 2018 and the minimum version for building the kernel with LLVM is 10.0.1 so there is no issue introduced: Link: https://github.com/llvm/llvm-project/commit/ee5be798dae30d5f9414b01f76ff807edbc881aa Link: https://lkml.kernel.org/r/20210802210307.3202472-1-nathan@kernel.org Reviewed-by: Nick Desaulniers Signed-off-by: Nathan Chancellor Signed-off-by: Steven Rostedt (VMware) --- Makefile | 1 - 1 file changed, 1 deletion(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index e4f5895badb5..d6915f361aa4 100644 --- a/Makefile +++ b/Makefile @@ -546,7 +546,6 @@ export RCS_TAR_IGNORE := --exclude SCCS --exclude BitKeeper --exclude .svn \ PHONY += scripts_basic scripts_basic: $(Q)$(MAKE) $(build)=scripts/basic - $(Q)rm -f .tmp_quiet_recordmcount PHONY += outputmakefile ifdef building_out_of_srctree -- cgit
