URL: https://github.com/apache/tvm/pull/13973
This PR introduces a new pass InjectPTXLDG32 to change the `if_then_else`
call node to `ptx_pred_ldg32` call node. When the store buffer is local and the
load value is global, the pass can change the if_then_else pattern to a ptx
pattern.
Test the pass with
~~~python
with tvm.transform.PassContext(config={"tir.ptx_pred_ldg32": True}):
mod = tvm.build(f, target="cuda")
