I don't know about that one. There are probably still a few places left that depend on this property, but we should get rid of them and just use "idx_count".

"count" is not used here.

We do have "ctx->parser->shader_desc.temp_count" though, and that's what we should use here.

And we should probably just validate that DCL_TEMPS is consistent with "ctx->parser->shader_desc.temp_count" here.
