Based on the algo from NV50LegalizeSSA::handleDIV() and handleMOD(). See also trans_idiv() in freedreno/ir3/ir3_compiler.c (which was an adaptation of the nv50 code from Ilia Mirkin). A python/numpy script which implements the same algorithm (and is possibly useful for debugging or analysis) can be found here: http://people.freedesktop.org/~robclark/div-lowering.py I've tested this on i965 hacked up to insert the idiv lowering pass, and on freedreno with NIR frontend.
