ddbfb6f2 - perf build: Remove PERF_HAVE_DWARF_REGS

Fri, 08 Nov 2024 23:46:05 +0000

perf build: Remove PERF_HAVE_DWARF_REGSPERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.cfile. There are no more architecture dwarf-regs.c files, selection isdone using constants from the ELF file rather than conditionalcompilation. When removing PERF_HAVE_DWARF_REGS was the only variablein the Makefile, remove the Makefile.Add missing SPDX for RISC-V Makefile.Reviewed-by: Masami Hiramatsu (Google) Signed-off-by: Ian Rogers Cc: Anup Patel Cc: Yang Jihong Cc: Palmer Dabbelt Cc: David S.

c2bd08ba - treewide: remove meaningless assignments in Makefiles

Wed, 21 Feb 2024 13:42:01 +0000

treewide: remove meaningless assignments in MakefilesIn Makefiles, $(error ), $(warning ), and $(info ) expand to the emptystring, as explained in the GNU Make manual [1]: "The result of the expansion of this function is the empty string."Therefore, they are no-op except for logging purposes.$(shell ...) expands to the output of the command. It expands to theempty string when the command does not print anything to stdout.Hence, $(shell mkdir ...) is no-op except for creating the directory.Remove meaningless assignments.[1]: https://www.gnu.org/software/make/manual/make.html#Make-Control-FunctionsSigned-off-by: Masahiro Yamada Reviewed-by: Arnaldo Carvalho de Melo Reviewed-by: Ian Rogers Link: https://lore.kernel.org/r/20240221134201.2656908-1-masahiroy@kernel.orgSigned-off-by: Namhyung Kim Cc: Mark Rutland Cc: Peter Zijlstra Cc: Adrian Hunter Cc: Arnaldo Carvalho de Melo Cc: Jiri Olsa Cc: Alexander Shishkin Cc: Ingo Molnar Cc: linux-kbuild@vger.kernel.orgCc: linux-kernel@vger.kernel.orgCc: linux-perf-users@vger.kernel.org List of files: /linux-6.15/tools/perf/arch/loongarch/Makefile
