Subject: Fixed ca65's BRK instruction encoding for the 65816.
X-Git-Tag: V2.16~45^2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=7e8bb7b700572a50ed4f1e87ebeea4fd35177459;p=cc65

Fixed ca65's BRK instruction encoding for the 65816.

BRK is two bytes on all 6502 variants; but, the 65816's maker declared officially that assemblers should support an optional operand.
