Tres Popp	d086b8a0ec	Correct HLO atan2 lowering in cases of -inf and -0 inputs. This is being done by just removing the approximation and lowering to atan2 lib calls later to make the implementation the same as XLA. Note that if the approximation is brought back later, it can be fixed by changing the IR checking `less-than(X, 0)` to `less-than(copysign(X, 1), 0)` PiperOrigin-RevId: 356253941	2021-02-08 06:58:04 -08:00
Rahul Joshi	bbaad416a1	[MLIR] Update tests to eliminate public function declarations. - Also fixed kernel_gen embed_memref_prints to mark the declarations inserted private. - This is in prep for proposed MLIR change to disallow public declarations.

A. Unique TensorFlower	bae0815ef0	[MLIR][KernelGen] Legalize `atan` to approximation PiperOrigin-RevId: 335417836	2020-10-05 08:05:52 -07:00
A. Unique TensorFlower	049ca060a1	[MLIR][KernelGen] Legalize `atan2` to approximation Legalize `atan2` analogously to XLA. `atan2` is first reduced to `atan` on the interval [-1, 1] and subsequently approximated. This CL also adds e2e tests for trigonometric approximations. PiperOrigin-RevId: 334794336	2020-10-01 05:34:48 -07:00
