I'm pretty sure that is loading a 32 bit value. I believe that 'h' is
for 16 bit and 'w' is 32 bit. I haven't seen that syntax for the source,
but my guess would be that it is an assembler directive of some sort
that will get translated into a memory reference of a register/offset,
but it seems like it would need to be PC-relative which that instruction
wouldn't support directly anyway.
Was this input for an assembler or output from a disassembler? If this
is from a disassembly of a dynamically relocatable object, it might
have gotten confused by an instruction being the target of a relocation.
