From 7f1bc2851325c013fe525264a5eb9f402a82ad4e Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 16 Feb 2018 15:45:33 -0500 Subject: [PATCH] tcg/mips: Add use_mips32r6_instructions definition Add definition use_mips32r6_instructions to the MIPS TCG backend which is constant 1 when built for MIPS release 6. This will be used to decide between pre-R6 and R6 instruction encodings.
