Subject: [PATCH 2/2] perf: Normalize gcc parameter when generating arch errno table
Date: Fri, 14 Feb 2020 02:21:06 +0800	[thread overview]
Message-ID: <1581618066-187262-2-git-send-email-zhe.he@windriver.com> (raw)
In-Reply-To: <1581618066-187262-1-git-send-email-zhe.he@windriver.com>

From: He Zhe <zhe.he@windriver.com>

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
