Compiler generates illegal parallel instruction that causes assembler to issue a valid error

XMLWordPrintable

    • Type: Bug
    • Resolution: Fixed
    • Priority: Medium

      The C28 compiler generates below illegal parallel instruction that causes assembler to issue a valid error.

          MPYF32 R1H,R2H,R1H  
||  MOV32 R0H,@$BLOCKED(||tempInput||)+4,GT

      Above parallel instruction is only legal with an unconditional MOV32.
      The attached test case has this line ...

        tempInput2.x.a = (temp5 * temp4 + temp6 * temp3);

      All variables are of type float. Build it ...

      % cl2000 -@options.txt -s test.c
"test.asm", ERROR!   at line 237: [E0802] Incorrect instruction/operands used in parallel operation
1 Assembly Error, No Assembly Warnings
                MPYF32    R1H,R2H,R1H           ; [CPU_FPU] |43|
        ||      MOV32     R0H,@$BLOCKED(||tempInput||)+4,GT ; [CPU_FPU] |40|
