Subject: [PATCH V2 1/4] riscv: Separate patch for cflags and aflags
Date: Thu, 16 Jan 2020 22:30:26 +0800	[thread overview]
Message-ID: <20200116143029.31441-1-guoren@kernel.org> (raw)

From: Guo Ren <ren_guo@c-sky.com>

Use "subst fd" in Makefile is a hack way and it's not convenient
to add new ISA feature. Just separate them into riscv-march-cflags
and riscv-march-aflags.
