/* Table of instructions. Each instruction is defined by the following macro: Insn(enumval, fmt, attr) The format string 'fmt' has the following expansions: %r - A register %m - A memory location. %l - A location (either register or memory) %x - Any value. %[1-9]*t - Mode of an operand. The optional number preceeding it is the operand desired for the mode. %v - a value (ie, immediate integer or label) Currently, there aren't any attrs, because none were needed yet. Eventually, they'll probably include flag setting and so on. For technical reasons, the indexing on use and def statments is 1-based, instead of 0-based. (0 is the sentinel value). */ /* Note, the mov instruction is specified in an overly general manner. */ Insn(Inone, "BAD_INSN", Use(), Def()) Insn(Imov, "\tmov%t %x,%x\n", Use(.l={1}), Def(.l={2})) Insn(Imovz, "\tmovz%1t%2t %x,%x\n", Use(.l={1}), Def(.l={2})) Insn(Imovs, "\tmovs%1t%2t %x,%x\n", Use(.l={1}), Def(.l={2})) Insn(Ilea, "\tlea%t %x,%x\n", Use(.l={1}), Def(.l={2})) Insn(Iadd, "\tadd%t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Isub, "\tsub%t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Imul, "\tmul%t %r\n", Use(.l={1},.r={Reax}), Def(.r={Reax,Redx})) Insn(Idiv, "\tdiv%t %r\n", Use(.l={1},.r={Reax,Redx}), Def(.r={Reax,Redx})) Insn(Ineg, "\tneg%t %r\n", Use(.l={1}), Def(.l={1})) Insn(Iand, "\tand%t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Ior, "\tor%t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Ixor, "\txor%t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Inot, "\tnot%t %x\n", Use(.l={1}), Def(.l={1})) Insn(Ishl, "\tsal%2t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Isar, "\tshr%2t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Ishr, "\tshr%2t %r,%x\n", Use(.l={1,2}), Def(.l={2})) Insn(Itest, "\ttest%t %r,%r\n", Use(.l={1,2}), Def(.l={2})) Insn(Icmp, "\tcmp%t %r,%r\n", Use(.l={1,2}), Def(.l={2})) Insn(Ipush, "\tpush%t %r\n", Use(.l={1}), Def()) Insn(Ipop, "\tpop%t %r\n", Use(.l={1}), Def()) /* branch instructions */ Insn(Isetz, "\tsetz %v\n", Use(), Def(.l={2})) Insn(Isetnz, "\tsetnz %v\n", Use(), Def(.l={2})) Insn(Isetlt, "\tsetlt %v\n", Use(), Def(.l={2})) Insn(Isetle, "\tsetle %v\n", Use(), Def(.l={2})) Insn(Isetgt, "\tsetgt %v\n", Use(), Def(.l={2})) Insn(Isetge, "\tsetge %v\n", Use(), Def(.l={2})) /* branch instructions */ Insn(Icall, "\tcall %v\n", Use(.l={1}), Def()) Insn(Ijmp, "\tjmp %v\n", Use(.l={1}), Def()) Insn(Ijz, "\tjz %v\n", Use(.l={1}), Def()) Insn(Ijnz, "\tjnz %v\n", Use(.l={1}), Def()) Insn(Ijl, "\tjl %v\n", Use(.l={1}), Def()) Insn(Ijle, "\tjle %v\n", Use(.l={1}), Def()) Insn(Ijg, "\tjg %v\n", Use(.l={1}), Def()) Insn(Ijge, "\tjge %v\n", Use(.l={1}), Def()) Insn(Iret, "\tret\n", Use(), Def()) /* not really an insn... */ Insn(Ilbl, "%v:\n", Use(), Def())
