PowerPC 750CL instruction bit patterns

PowerPC 750CL instruction bit patterns

The following listing describes the static bit pattern of each opcode.

patterns.txt

Syntax:

line: opcode <pattern>...
pattern: start,stop,value

Pattern interpretation:

• Zero bit is MSB.
• start is the first bit of the mask (inclusive).
• stop is the last bit of the mask (inclusive).
• value is the decimal value behind the mask.

masks.txt

Syntax:

line: opcode <mask> <value>

To check whether an instruction matches an opcode, compute instruction & mask == value.
