nolist ; ; This include file must be included to use the 8087 opcodes with RASM86. ; Future versions of RASM86 will eliminate the need for this file. ; st equ 0 st0 equ 0 st1 equ 1 st2 equ 2 st3 equ 3 st4 equ 4 st5 equ 5 st6 equ 6 st7 equ 7 ; ;M equ word ptr 0ÆbpÅ ; Define a memory reference example. ; ; RASM86 now implements the following opcodes. The operations on ; the 8087 stack have the same mnemonics as Intel uses, with one ; addition. Intel uses FXCH for 8087 exchanges, and XCHG for 8086 ; exchanges. This is confusing, so we defined both FXCH and FXCHG. ; ; For the memory reference opcodes, we include the length (16, 32, 64, 80) ; right in the opcode. In spite of this, RASM86 still requires that you ; use 'byte pointer' or 'word pointer' on the memory operand if it is not ; already defined to have an alignment attribute. We'll fix it someday. ; By contrast, the Intel assembler picks up the length from the operand ; definition. This leads to the anomaly that there are valid 8087 opcodes ; that the Intel assembler cannot produce, since it cannot define memory ; operands of the appropriate length. We think our approach is better. ; ; Here are the 8087 opcode formats. Remove the semicolons to produce a ; complete test case. ; ; f2xm1 ; fabs ; fadd ; fadd st,st1 ; fadd st1,st ; fadd32 M ; fadd64 M ; faddp st1,st0 ; fbld M ; fbstp M ; fchs ; fclex ; fcom ; fcom st1 ; fcom32 M ; fcom64 M ; fcomp ; fcomp st1 ; fcom32p M ; fcom64p M ; fcompp ; fdecstp ; fdisi ; fdiv ; fdiv st,st1 ; fdiv st1,st ; fdiv32 M ; fdiv64 M ; fdivp st1,st0 ; fdivr ; fdivr st,st1 ; fdivr st1,st ; fdivr32 M ; fdivr64 M ; fdivrp st1,st ; feni ; ffree st1 ; fiadd16 M ; fiadd32 M ; ficom16 M ; ficom32 M ; ficom16p M ; ficom32p M ; fidiv16 M ; fidiv32 M ; fidivr16 M ; fidivr32 M ; fild16 M ; fild32 M ; fild64 M ; fimul16 M ; fimul32 M ; fincstp ; finit ; fist16 M ; fist32 M ; fist16p M ; fist32p M ; fisub16 M ; fisub32 M ; fisubr16 M ; fisubr32 M ; fld st1 ; fld32 M ; fld64 M ; fld80 M ; fld1 ; fldcw word ptr ÆbpÅ ; fldenv word ptr 6ÆbpÅ ; fldl2e ; fldl2t ; fldlg2 ; fldln2 ; fldpi ; fldz ; fmul ; fmul st1,st ; fmul st,st1 ; fmul32 M ; fmul64 M ; fmulp st1,st ; fnclex ; fndisi ; fneni ; fninit ; fnop ; fnsave M ; fnstcw M ; fnstenv M ; fnstsw M ; fpatan ; fprem ; fptan ; frndint ; frstor M ; fsave M ; fscale ; fsqrt ; fst st1 ; fst32 M ; fst64 M ; fstcw M ; fstenv M ; fstp st1 ; fst32p M ; fst64p M ; fst80p M ; fstsw M ; fsub ; fsub st,st1 ; fsub st1,st ; fsub32 M ; fsub64 M ; fsubp st1,st ; fsubr ; fsubr st,st1 ; fsubr st1,st ; fsubr32 M ; fsubr64 M ; fsubrp st1,st ; ftst ; fwait ; fxam ; fxch ; fxch st1 ; fxtract ; fyl2x ; fyl2xp1 ; end «eof»
