Hi Kazu, Venkat, and all, This is the first of several posts containing a submission of a port extending the h8/300 tools to cover the new h8300sx architecture. The files are so heavily changed that I'm just going to submit them inline, rather than as diffs. They're all interdependant (you have to take them all together), but I'll post them separately just because they're large. The following is the shared file include/opcode/h8300.h, which defines the opcode table for gas, sim, and opcodes/disasm. Changes for those components will follow. 2003-05-14 Michael Snyder and Bernd Schmidt and Alexandre Oliva * opcode/h8300.h: Add h8300sx insns, addressing modes, etc.
