From 38dffe1e4dde1d3174fdce09d67370412843ebb5 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Thu, 10 Oct 2019 23:01:57 +0800 Subject: MIPS: elf_hwcap: Export userspace ASEs A Golang developer reported MIPS hwcap isn't reflecting instructions that the processor actually supported so programs can't apply optimized code at runtime. Thus we export the ASEs that can be used in userspace programs.
