* m32c.cpu (f-dsp-8-s24, Dsp-8-s24): New.
(mov-dspsp-dst-defn, mov-src-dspsp-defn, mov16-dspsp-dst-defn, mov16-src-dspsp-defn, mov32-dspsp-dst-defn, mov32-src-dspsp-defn): dsp8[sp] is signed. (mov.WL:S #imm,A0/A1): dsp24 is signed (i.e. -0x800000..0xffffff). (mov.BW:S r0,r1): Fix typo r1l->r1. (tst): Allow :G suffix. * m32c.opc (parse_signed24): New, for -0x800000..0xffffff. * m32c-asm.c: Regenerate. * m32c-desc.c: Regenerate. * m32c-desc.h: Regenerate. * m32c-dis.c: Regenerate. * m32c-ibld.c: Regenerate. * m32c-opc.c: Regenerate. * m32c-opc.h: Regenerate.
