[PULL 22/30] qapi rocker: Elide redundant has_FOO in generated C |
Date: |
Wed, 14 Dec 2022 08:47:13 +0100 |
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with. Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step. This is the step for qapi/rocker.json.
Said commit explains the transformation in more detail. The invariant
violations mentioned there do not occur here.
