Subject: [PATCH 1/2] [AMDGPU/VOP3P] - Add tied wmma_f16 pseudos
Add intrinsics for `wmma_f16` and `wmma_bf16`, which stay as two-address
instructions.
This is a requirement for a future optimization
regarding wmma instructions.
The new changes make use of the `op_sel` argument of `wmma` instructions
to read from the upper halves of the input
accumulator and write to the upper halves of the output matrix.
With two-address instructions, we can guarantee that the content
of the upper halves is the same as the input
accumulator.
With three-address instructions, the output
registers do not copy the content of the input
registers. Instead, the upper halves
remain unchanged from their previous values.
This can cause issues if there are unexpected
values remaining in these registers.
For example:
```
v_wmma_f16_16x16x16_f16 v[0:7], ..., v[24:31]
v_wmma_f16_16x16x16_f16 v[32:30], ..., v[24:31]
```
After these two instructions run, there is
no guarantee that the content of bits 16-31 of
`v[0:7]` are the same as the ones from `v[24:31]`.
If we have another instruction like the following:
```
v_wmma_f16_16x16x16_f16 v[0:7], v[24:31], v[32:49], v[0:7] op_sel:[0,0,1]
```
We read from the upper halves of `v[0:7]`, but
the content is not necessarily correct.
For our purpose, we create new pseudo instructions, while maintaining
the behavior of the original instructions.
