Subject: [RFC PATCH V2 19/38] riscv: s64ilp32: Add ELF32 support
Date: Sun, 12 Nov 2023 01:14:55 -0500 [thread overview]
Message-ID: <20231112061514.2306187-20-guoren@kernel.org> (raw)
In-Reply-To: <20231112061514.2306187-1-guoren@kernel.org>
From: Guo Ren <guoren@linux.alibaba.com>
Use abi_len to distinct ELF32 and ELF64 because s64ilp32 is xlen=64 and
abi_len=32 (__SIZEOF_POINTER__=4). And s64ilp32 is an ELF32 based the
same as s32ilp32.
