From 5cf9de4b727b9311d5883fa682b1bd00b50647a8 Mon Sep 17 00:00:00 2001 From: Simon Dardis Date: Wed, 16 May 2018 10:03:05 +0000 Subject: [PATCH] [mips] Add support for isBranchOffsetInRange and use it for MipsLongBranch Add support for this target hook, covering MIPS, microMIPS and MIPSR6, along with some tests. Also add missing getOppositeBranchOpc() cases exposed by the tests.
