For detailed information on the SH machine instruction set, see [SH-Microcomputer User's Manual] (Renesas) or [SH-4 32-bit CPU Core Architecture] (SuperH) and [SuperH (SH) 64-Bit RISC Series] (SuperH).
as implements all the standard SH opcodes. No additional pseudo-instructions are needed on this family. Note, however, that because as supports a simpler form of PC-relative addressing, you may simply write (for example)
mov.l bar,r0 |
where other assemblers might require an explicit displacement to bar from the program counter:
mov.l @(disp, PC) |
