Cannot infer temporary bitwidth when a previously inferred temporary on RHS #44

Closed dmlockhart closed 9 years ago

dmlockhart commented 10 years ago

PyMTL allows the creation of temporaries in a number of scenarios when the right-hand-side (RHS) of an assignment allows for easy bitwidth inference:

  some_temp = s.port_a and s.port_b
  s.out.value = some_temp

However, if the RHS of a temporary assignment contains another temporary, this fails:

  some_temp = s.port_a and s.port_b
  some_temp2 = some_temp and s.port_c  # FAILS due to some_temp on RHS

Awesome!
