R600/SI: Fix assertion on infinite loops. This isn't the most useful case to fix in the real world, but bugpoint runs into this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201177 91177308-0d34-0410-b5e6-96231b3b80d8 2014-02-11 21:12:38 +00:00			`; RUN: llc -march=r600 -mcpu=SI -verify-machineinstrs < %s \| FileCheck -check-prefix=SI %s`

R600/SI: Print more immediates in hex format Print in decimal for inline immediates, and hex otherwise. Use hex always for offsets in addressing offsets. This approximately matches what the shader compiler does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206335 91177308-0d34-0410-b5e6-96231b3b80d8 2014-04-15 22:32:49 +00:00			`; SI: V_MOV_B32_e32 [[REG:v[0-9]+]], 0x3e7`
