From df4eeed0befc39385f3baa40b4f38183b9c76363 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 28 Jun 2014 17:48:42 -0700 Subject: i965/disasm: Properly disassemble jump targets on Gen4-5. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, our dissasembly for flow control instructions looked like: 0x00000040: else(8) ip 65540D { align16 switch }; It didn't print InstCount properly for ELSE/ENDIF, and didn't even attempt to disassemble PopCount. Now it looks like: 0x00000040: else(8) Jump: 4 Pop: 1 { align16 switch }; which is much more readable.
