HI, list,
i don't understand why glsl source have so many 'cast to void' operations,
like this.
ir_rvalue *
ast_node::hir(exec_list *instructions,
struct _mesa_glsl_parse_state *state)
{
(void) instructions;
(void) state;
return NULL;
}
i think it's totally void operation, do you guy just make gcc compiler
happy?
Yes, the purpose is only to avoid unused variable warnings emitted by
the compiler.
yes it is. now i understood. clean code!
