Subject: Refactor ir_expression::get_num_operands.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7dd6adbe2e791b22de97175a8715ef1217619c99;p=mesa.git

Refactor ir_expression::get_num_operands.

A new static version takes an ir_expression_operation enum, and the
original non-static version now uses it.  This will make it easier to
read operations (where the ir_expression doesn't yet exist).
