Greg King	b2c1a77bb3	Fixed the cc65 code that optimizes 16-bit compares when the high bytes are known to be equal. Only the low bytes are compared. Originally, signed 16-bit compares were optimized into signed 8-bit compares. But, the sign bits are in the high bytes; and, they're equal. Therefore, the low bytes always must be compared as unsigned numbers. Fixes #1348.	2020-12-24 12:27:09 -05:00

Fixes #1348.
