From: Qian Jianhua Date: Tue, 22 Dec 2020 18:54:34 +0000 (+0000) Subject: arm&aarch64: subdivide the type attribute "alu_shfit_imm" X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ae27ce51e4860388d2b4129e2a80cc7f292368b5;p=gcc.git arm&aarch64: subdivide the type attribute "alu_shfit_imm" The type attribute "alu_shfit_imm" is subdivided into "alu_shift_imm_lsl_1to4" and "alu_shift_imm_other", to accommodate optimazations of some microarchitectures.
