The pipeline program is split into groups of instructions, and a custom instruction is generated for each group that has more than one instruction. Special care is taken the instructions that can do thread yield (RX, extern) and for those that can change the instruction pointer (TX, near/far jump).

The pipeline program is split into groups of instructions, and a custom instruction is generated for each group that has more than one instruction. Special care is taken the instructions that can do thread yield (RX, extern) and for those that can change the instruction pointer (TX, near/far jump).
