Erico Nunes	3e2b2c3bdd	lima/ppir: add support and folding for fclamp_pos ... Now that ppir uses its own folding for dest modifiers, we can add folding for fclamp_pos which was previously unused. We borrow the nir optimization pass from Panfrost to create a nir_op_fclamp_pos_mali when possible and reuse the dest modifier lowering to optimize that to a modifier when possible.

Vasily Khoruzhick	2756b62917	lima/gpir: add better lowering for ftrunc ... GP doesn't support ftrunc natively and unfortunately one in generic opt_algebraic is not GP-friendly either. Introduce our own lowering that utilizes fsign() that GP supports: ftrunc(a) = fmul(fsign(a), ffloor(fmax(a, -a))) Tested-by: Andreas Baierl <ichgeh@imkreisrum.de> Reviewed-by: Andreas Baierl <ichgeh@imkreisrum.de> Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4126>	2020-03-16 16:28:33 -07:00
