[llvm] r283570 - AMDGPU/SI: Emit fixups for long branches

[Rafael Avila de Espindola via llvm-commits]

BTW, if I try to print to a .s and run llvm-mc I get

test-master.s:308:28: error: not a valid operand.
        s_sub_u32 vcc_lo, vcc_lo, (BB4_3+4)-BB4_1

llvm-mc should really be able to parse the llc output.

Cheers,
Rafael
