SuperH has a mov #imm, Rx that can take an 8-bit #imm. But you're right, literal pools were used just like on ARM. Things I liked about SuperH: 16 bit fixed-width insn format (except for some SH2A and DSP ops), T flag for bit manipulation ops, GBR to enable scaled loads with offset, xtrct instruction, single-cycle division insns (div0, div1), MAC insns. In terms of code density SH was quite effective, see here http://web.eece.maine.edu/~vweaver/papers/iccd09/iccd09_density.pdf http://web.eece.maine.edu/~vweaver/papers/iccd09/iccd09_dens... or here http://www.deater.net/weave/vmwprod/asm/ll/ll.html http://www.deater.net/weave/vmwprod/asm/ll/ll.html
