From: Kito Cheng Date: Fri, 10 Apr 2020 09:20:18 +0000 (+0800) Subject: RISC-V: Update march parser X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ca1a9763a1f635d2687ebd5009dd61d4fd0ab5fb;p=gcc.git RISC-V: Update march parser - The arch string rule has changed in latest spec, it introduced new multi-letter extension prefix with 'h' and 'z', and drop `sx`. also adjust parsing order for 's' and 'x'. gcc/ChangeLog * riscv-common.c (parse_sv_or_non_std_ext): Rename to parse_multiletter_ext.
