Cannot use bbs or bbc instructions on the SPC700 platform.

[undisbeliever]

While testing the SPC700 platform I was unable to write a test case for the bbs or bbc SPC700 instructions. I see them referenced in src/wiz/platform/spc700_platform.cpp, but I am unable to write wiz code that assembles to these instructions.

I did not include this failing test case to my spc700-fixes Pull Request as I am unsure if these wiz statements are correct or not.

bank zeropage @ 0x000 : [vardata;   0x100];
bank code     @ 0x200 : [constdata; 0x100];

in zeropage {
    var _padding1       : [u8; 0x08];

    var zp_u8_08        : u8;           // address = 0x08
}

// BLOCK 0000
in code {

func test() {

// BLOCK  0000  23 08 01   bbs $08.1,$0204
// BLOCK  0003  00         nop
    goto Label1 if zp_u8_08 $ 1 == true;
    nop();
Label1:

// BLOCK  0004  53 08 01   bbc $08.2,$0208
// BLOCK  0007  00         nop
    goto Label2 if zp_u8_08 $ 2 == false;
    nop();
Label2:

// BLOCK  0008  63 08 01   bbs $08.3,$020c
// BLOCK  000B  00         nop
    if (zp_u8_08 $ 3) == false {
        nop();
    }

// BLOCK  000C  93 08 01   bbc $08.4,$0210
// BLOCK  000F  00         nop
    if (zp_u8_08 $ 4) == true {
        nop();
    }

// BLOCK  0010  6F         rts
}

}
