fixups yet, and doesn't handle actually encoding operand values, but this is enough for llc -show-mc-encoding to show the base instruction encoding information, e.g.: mflr r0 ; encoding: [0x7c,0x08,0x02,0xa6] stw r0, 8(r1) ; encoding: [0x90,0x00,0x00,0x00] stwu r1, -64(r1) ; encoding: [0x94,0x00,0x00,0x00] Ltmp0: lhz r4, 4(r3) ; encoding: [0xa0,0x00,0x00,0x00] cmplwi cr0, r4, 8 ; encoding: [0x28,0x00,0x00,0x00] beq cr0, LBB0_2 ; encoding: [0x40,0x00,0x00,0x00] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119116 91177308-0d34-0410-b5e6-96231b3b80d8
