Subject: [PATCH 2/5] ppc: pass -mno-spe and -mspe=no to cc-option
Date: Thu, 30 Apr 2020 02:34:16 +0900 [thread overview]
Message-ID: <20200429173419.681074-3-masahiroy@kernel.org> (raw)
In-Reply-To: <20200429173419.681074-1-masahiroy@kernel.org>
My compiler does not understand -mno-spe or -msped=n.
powerpc-linux-gcc: error: unrecognized command line option '-mno-spe'; did you mean '-fno-see'?
powerpc-linux-gcc: error: unrecognized command line option '-mspe=no'
Pass them to cc-option becasue this is what Linux does.
Also, assign the compiler flags to CFLAGS, AFLAGS, and CPPFLAGS properly.
