- parseInstFile :: FilePath -> IO [Inst]
Assembler drivers
parseInst :: ByteString -> Either [String] [Inst] Source
parse instructions from a ByteString data
Example:
> parseInst (B.pack "mov r0,1\n halt\n") [MOVI R0 1,HALT]
parseInstFile :: FilePath -> IO [Inst] Source
parse instructions from a file
Example:
> parseInstFile "examples/test0.asm" [MOVI R0 1,HALT]
Assembler parse examples
Parse Example:
from text to the Inst data type
text -> Inst data type ---------------------------------------- nop -> NOP halt -> HALT mov r1, 100 -> MOVI R1 100 mov r1, r2 -> MOV R1 R2 mov r1, pc -> MOVPC R1 add r1, r2, r3 -> ADD R1 R2 R3 sub r1, r2, r3 -> SUB R1 R2 R3 cmp r1, r2 -> CMP R1 R2 abs r1, r2 -> ABS R1 R2 ash r1, r2, r3 -> ASH R1 R2 R3 mul r1, r2, r3 -> MUL R1 R2 R3 div r1, r2, r3 -> DIV R1 R2 R3 and r1, r2, r3 -> AND R1 R2 R3 or r1, r2, r3 -> OR R1 R2 R3 not r1, r2 -> NOT R1 R2 xor r1, r2, r3 -> XOR R1 R2 R3 lsh r1, r2, r3 -> LSH R1 R2 R3 b eq, -3 -> BRI FCEQ (-3) jmp 3 -> JRI 3 jmp r1 -> J R1 call r1 -> CALL R1 ret -> RET ld r1, m(r2) -> LD R1 R2 st m(r1), r2 -> ST R1 R2
