* tgsi/lowering: improved lowering for LRPRussell King2016-04-191-35/+20
| | | | | | | | | | | Provide an improved lowering for LRP, which can be implemented in two MAD instructions with a bit of rearranging of the equation, rather than the literal implementation of two multiplies, an add and a subtract.

* tgsi/lowering: improved lowering for XPDRussell King2016-04-191-22/+13
| | | | | | | | | Improve XPD lowering to consume less instructions by using the MAD instruction to perform the multiply and subtraction together. Signed-off-by: Russell King <rmk@arm.linux.org.uk> Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Rob Clark <robclark@freedesktop.org>
* tgsi/lowering: add support for lowering TRUNCRussell King2016-04-191-0/+84
| | | | | | | | | | | | | | Add support for lowering TRUNC using the following sequence: FRC tmpA, |src| SUB tmpA, |src|, tmpA CMP dst, -tmpA, tmpA Note that this is incompatible with FRC lowering.

* tgsi/lowering: add support for lowering FLR and CEILRussell King2016-04-191-20/+147
| | | | | | | | | | | | | | | | Add support for lowering FLR and CEIL to FRC/SUB and FRC/ADD instructions for GPUs that support FRC but not FLR or CEIL. Since these uses FRC, it is invalid to ask for FLR or CEIL to be lowered along with FRC, so add an assert to catch this invalid configuration. We also need to deal with FLR instructions emitted by the lowering code. Fix these up with the FRC+SUB equivalent when FLR lowering is enabled.

* gallium: remove TGSI_SAT_MINUS_PLUS_ONEMarek Olšák2015-05-201-2/+1
| | | | | | | | It's a remnant of some old NV extension. Unused. I also have a patch that removes predicates if anyone is interested. Reviewed-by: Roland Scheidegger <sroland@vmware.com>
* tgsi/lowering: don't forget interp for BCOLOR inputsRob Clark2015-03-031-3/+7
| | | | | | | | To lower two sided color, tgsi_lowering creates additional BCOLOR inputs (matching up to the BCOLOR outputs on the vert shader). These inputs should copy the interpolation state of their matching COLOR input. Signed-off-by: Rob Clark <robclark@freedesktop.org>

* gallium: Copy fd_lowering.[ch] to tgsi_lowering.[ch] for code sharing.Eric Anholt2014-10-081-0/+1573
Lots of drivers need to transform the weird instructions in TGSI into reasonable scalar ops, and this code can make those translations canonical. Acked-by: Rob Clark <robclark@freedesktop.org>
