From 3d304f48cafbff4b7a1c0a9d338fb20aa4e4934b Mon Sep 17 00:00:00 2001 From: Andrew Bennett Date: Mon, 18 Jan 2016 21:25:19 +0000 Subject: [PATCH] MIPS: Only build microMIPS specific simulator functions if microMIPS support is required. This fixes PR sim/19441. In the MIPS simulator the microMIPS functions in micromips.igen were not predicated on the microMIPS models. This was causing build issues for some target triples. This patch sets all the microMIPS specific functions to only be built if the micromips32, micromips64 or micromipsdsp models are used.
