Subject: [PATCH 1/2] LoongArch: Redefine macro LEAF/ENTRY.
Date: Tue, 1 Aug 2023 15:09:01 +0800 [thread overview]
Message-ID: <20230801070902.1385953-2-dengjianbo@loongson.cn> (raw)
In-Reply-To: <20230801070902.1385953-1-dengjianbo@loongson.cn>
The following usage of macro LEAF/ENTRY are all feasible:
1. LEAF(fcn) -- the align value of fcn is .align 3(default value)
2. LEAF(fcn, 6) -- the align value of fcn is .align 6
