By combining instruction compression and macro-op fusion you get the net effect of looking like you have a bunch of extra higher level opcodes in your ISA.
Compress a shift and load into a 32-bit word and macro-op fuse those and you have in effect an index based load instruction, without sucking up ISA encoding space for it.
