Subject: [PATCH v1 RFC Zisslpcfi 20/20] riscv: select config for shadow stack and landing pad instr support
Date: Sun, 12 Feb 2023 20:53:49 -0800	[thread overview]
Message-ID: <20230213045351.3945824-21-debug@rivosinc.com> (raw)
In-Reply-To: <20230213045351.3945824-1-debug@rivosinc.com>

This patch selects config shadow stack support and landing pad instr
support. Since shadow stack support and landing instr support relies
on ELF header, this change also selects ARCH_USE_GNU_PROPERTY and
ARCH_BINFMT_ELF_STATE.
