Carl Worth	1660a29547	exec_node: Add new talloc-based new() ... And fix all callers to use the tallbac-based new for exec_node construction. We make ready use of talloc_parent in order to get valid, (and appropriate) talloc owners for everything we construct without having to add new 'ctx' parameters up and down all the call trees. This closes the majority of the memory leaks in the glsl-orangebook-ch06-bump.frag test: total heap usage: 55,623 allocs, 42,672 frees (was 14,533 frees) Now 76.7% leak-free. Woo-hoo!	2010-06-23 18:59:35 -07:00
Eric Anholt	4b6fd39c89	Add a virtual clone() method to ir_instruction. ... This will be used by function inlining, the linker, and avoiding double usage of the LHS deref chains in ++, *=, and similar operations.	2010-06-23 15:20:29 -07:00
