Virgil Dupras	af2c561c6b	zasm: begin erroring out reliably ... Up until now, invalid source input had undefined behavior. We're now beginning to define that behavior so that zasm can be a bit more usable.	2019-05-27 11:04:31 -04:00
Virgil Dupras	c40bc329d5	zasm: fix expr returning wrong values on first pass ... To run a parseExpr on first pass would always return a false success with dummy value because symbols are configured to always succeed on first pass. This would make expressions like ".fill 0x38-$" so bad things to labels because "0x38-$" wouldn't return the same thing on first and second pass. Revert to parsing literals and symbols after having scanned for expressions and add a special case specifically for char literals (which is why we scanned for literals and symbols first in the first place).	2019-05-20 10:46:27 -04:00
