Programming Note
bclr, bclrl, bcctr, and bcctrl each serve as both a basic and an extended mnemonic. The Assembler will recognize a bclr, bclrl, bcctr, or bcctrl mnemonic with three operands as the basic form, and a bclr, bclrl, bcctr, or bcctrl mnemonic with two operands as the extended form. In the extended form the BH operand is omitted and assumed to be 0b00.
