2010-08-13 | glsl2: Convert ir_constant_propagation to ir_rvalue_visitor. | Eric Anholt | |
This one is a little tricky because of the LHS handling. | |||
2010-08-09 | glsl2: Add constant propagation. | Eric Anholt | |
Whereas constant folding evaluates constant expressions at rvalue nodes, constant propagation tracks constant components of vectors across execution to replace (possibly swizzled) variable dereferences with constant values, triggering possible constant folding or reduced variable liveness. |
