Stephen Heumann	0df71da4f1	Change Byte -> UByte conversion to use a "Word -> UByte" conversion, rather than introducing a new "Byte -> UByte" conversion. ... The latter would require more changes to the code generator to understand it, whereas this approach doesn't require any changes. This is arguably less clean, but it matches other places where a byte value is subsequently operated on as a word without an explicit conversion, and the assembly instruction generated is the same.	2017-10-21 20:36:20 -05:00
Stephen Heumann	c28e48a54f	Do an explicit conversion when converting from signed to unsigned byte values. This is needed because the value is held in a 16-bit register, sign-extended. The high 8 bits need to be cleared to convert to an unsigned byte. ... This fixes the compca06.c test case. Note that this generates inefficient code in the case of loading a signed byte value and then immediately casting it to unsigned (it first sign-extends the value, then masks off the high bits). This should be optimized, but at least the generated code is correct now.	2017-10-21 20:36:20 -05:00
