From 3da96d6f13e05779de71009227137880d363ea2b Mon Sep 17 00:00:00 2001 From: Jessica Paquette Date: Mon, 4 Feb 2019 17:10:55 +0000 Subject: [PATCH] [GlobalISel] Introduce a generic floating point floor opcode, G_FFLOOR This introduces a generic opcode for floating point floor, working towards selecting @llvm.floor.
