Revision d1bc75d7595b237f78b594509ea7cc159f98cae9 authored by WANG Xuerui on 26 July 2022, 15:57:20 UTC, committed by Huacai Chen on 29 July 2022, 10:22:32 UTC
Support for the syntactic sugar is present in upstream binutils port from the beginning. Use it for shorter lines and better consistency. Generated code should be identical. Signed-off-by: WANG Xuerui <git@xen0n.name> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
