In the ROCm fork of PyTorch 2.9, Inductor currently has codegen support for fast_tanhf. However, there were some NaN issues in the original Triton implementation of fast_tanhf .
Upstream Triton has an improved fast_tanhf where the NaN issues are now fixed. This upstream commit has been backported to ROCm fork of Triton (see code comments).
A bump in the Triton commit is also needed.
