[llvm-commits] [patch] ARM/MC/ELF add new stub for movt/movw in ARMFixupKinds

[Jim Grosbach]

Sorta. getBinaryCodeForInst() is auto-generated by tablegen, so shouldn't be modified directly. The target can register hooks for instruction operands for any special encoding needs, including registering fixups, using the EncoderMethod string. For an example, have a look at the LDRi12 instruction and how it registers a fixup for the addrmode_imm12 operand when it needs one.
