radeonsi/nir: enable lowering of fpow
Lowering fpow in NIR rather than LLVM can be beneficial. Polaris results: Totals from affected shaders: SGPRS: 124928 -> 124896 (-0.03 %) VGPRS: 68616 -> 68332 (-0.41 %) Spilled SGPRs: 394 -> 413 (4.82 %) Spilled VGPRs: 0 -> 0 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 0 -> 0 (0.00 %) dwords per thread Code Size: 3668912 -> 3658368 (-0.29 %) bytes LDS: 0 -> 0 (0.00 %) blocks Max Waves: 18575 -> 18593 (0.10 %) Wait states: 0 -> 0 (0.00 %) Fixes: d6b753920677 "ac/nir: remove emission of nir_op_fpow" Tested-by: Dieter Nützel <[email protected]> Reviewed-by: Samuel Pitoiset <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
