[Mesa-dev] [PATCH 1/2] glsl: add a empty set_is_lhs on ast_node

[Alejandro Piñeiro]

Just to allow to call set_is_lhs on any ast_node without a casting. Useful
when processing a ast_node list that we know it contain ast_expression.
---

Worth to note that ast_node has other dummy implementations, like
ast_node::hir.
