Actually i was coming from an, given really constrained, addition to the
LoadPropagation pass, where i was told to fix it within...

[PATCH mesa 0/5] nouveau: codegen: Make use of double immediates
Hi All,
This series implements using double immediates in the nouveau codegen code.
This turns the following (nvc0) code:
1: mov u32 $r2 0x00000000 (8)
2: mov u32 $r3 0x3fe00000 (8)
3: add f64 $r0d $r0d $r2d (8)
Into:
1: add f64 $r0d $r0d 0.500000 (8)
This has been tested with the 2 double shader tests which I just send to
the piglet list. On a gk208 (gk110 / SM35)

[PATCH 0/3] nv50/ir: Preapre for running Opts inside a loop
Slowly we are getting to the point, that we miss enough optimization
opportunities as the result of our own passes.
For this we need to fix AlgebraicOpt to be able to handle mods on sources
without creating new issues.
The last patch enables looping opts.

[PATCH] nv50/ir: Propagate third immediate src when folding OP_MAD
That's very odd. LoadPropagation should have picked that up even in
its current form. Should try to figure out why it didn't and that is
likely to "fix" a *lot* more situations.
