From e4ffd066ff440a57097e9140fa9e16ceef905de8 Mon Sep 17 00:00:00 2001 From: He Zhe Date: Fri, 14 Feb 2020 02:21:06 +0800 Subject: perf: Normalize gcc parameter when generating arch errno table The $(CC) passed to arch_errno_names.sh may include a series of parameters along with gcc itself. To avoid overwriting the following parameters of arch_errno_names.sh and break the build like below, we just pick up the first word of the $(CC). find: unknown predicate `-m64/arch' x86_64-wrs-linux-gcc: warning: '-x c' after last input file has no effect x86_64-wrs-linux-gcc: error: unrecognized command line option '-m64/include/uapi/asm-generic/errno.h' x86_64-wrs-linux-gcc: fatal error: no input files Signed-off-by: He Zhe Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lore.kernel.org/lkml/1581618066-187262-2-git-send-email-zhe.he@windriver.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Makefile.perf | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tools/perf/Makefile.perf') diff --git a/tools/perf/Makefile.perf b/tools/perf/Makefile.perf index a02aca9b21f4..d15a311408f1 100644 --- a/tools/perf/Makefile.perf +++ b/tools/perf/Makefile.perf @@ -574,7 +574,7 @@ arch_errno_hdr_dir := $(srctree)/tools arch_errno_tbl := $(srctree)/tools/perf/trace/beauty/arch_errno_names.sh $(arch_errno_name_array): $(arch_errno_tbl) - $(Q)$(SHELL) '$(arch_errno_tbl)' $(CC) $(arch_errno_hdr_dir) > $@ + $(Q)$(SHELL) '$(arch_errno_tbl)' $(firstword $(CC)) $(arch_errno_hdr_dir) > $@ sync_file_range_arrays := $(beauty_outdir)/sync_file_range_arrays.c sync_file_range_tbls := $(srctree)/tools/perf/trace/beauty/sync_file_range.sh -- cgit v1.2.3
