Subject: [Buildroot] [PATCH V4 04/11] arch/csky: Add FLOAT_ABI compiler options
Date: Fri, 31 May 2019 14:39:01 +0800 [thread overview]
Message-ID: <1559284748-32011-5-git-send-email-guoren@kernel.org> (raw)
In-Reply-To: <1559284748-32011-1-git-send-email-guoren@kernel.org>
From: Guo Ren <ren_guo@c-sky.com>
C-SKY CPU is seperated into two ABIs:
- abiv1: mcore based ISA with ELF_NUM:39 and do not support FPU & VDSP.
(CPU: 610)
- abiv2: C-SKY own ISA with ELF_NUM:252 and support FPU & VDSP.
(CPU: 807, 810, 860)
BR2_GCC_TARGET_FLOAT_ABI will have a value for abiv1. Except the value
will always be "soft" because there's no FPU support in ck610, which is
the only core using abiv1.
