[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)
