Subject: [PATCH 03/31] perf: Normalize gcc parameter when generating arch errno table
Date: Fri,  3 Apr 2020 11:54:15 -0300	[thread overview]
Message-ID: <20200403145443.24774-4-acme@kernel.org> (raw)
In-Reply-To: <20200403145443.24774-1-acme@kernel.org>

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
