Subject: [PATCH 044/139] broadcom/qpu: fail packing on unhandled mul
|
|
pack/unpack
|
|
|
|
We are doing this for the ADD alu already and it may be helpful to
|
|
identify cases where we have QPU code with pack/unpack modifiers on
|
|
MUL opcodes that we then are not packing into the actual QPU
|
|
instructions.
