There was a problem hiding this comment.
i think we could still do sugaring in this case, i.e.:
with T.decl_buffer((256, 256)) as buffer:
T.evaluate(buffer.data)

This PR is the follow up of #13813. We simplify the printing output of `T.allocate` with `T.decl_buffer`. For example, we have a code snippet as ```python buffer_data = T.allocate(...) buffer = T.decl_buffer(..., data=buffer_data) T.evaluate(buffer_data) ``` Originally, we skip the `T.allocate` only if the var `buffer_data` defined by `T.allocate` is used only once by the following `T.decl_buffer`. This was due to the limitation of the old printer design. But in the new printer, we may automatically replace the `buffer_data` with `buffer.data` if skipping the definition of `buffer_data`. We are able to link all `buffer_data` usages together. So the new output result will be like ```python buffer = T.decl_buffer(...) T.evaluate(buffer.data) ```

…ipt printer (apache#13813) This PR implements the syntax sugar of `T.allocate` with `T.decl_buffer` for new TVMScript printer. This syntax sugar will skip the `T.allocate`, when its body is a matched `T.decl_buffer`, and the `Var` defined in `T.allocate` is only used in that `T.decl_buffer`. For example, it will change ```python buffer_data = T.allocate([128, 128]) buffer = T.decl_buffer([128, 128], data=buffer_data) ``` into ```python buffer = T.decl_buffer([128, 128]) ``` but keep the following `T.allocate` unchanged: ```python buffer_data = T.allocate([128, 128]) buffer_0 = T.decl_buffer([128, 128], data=buffer_data) buffer_1 = T.decl_buffer([128, 128], data=buffer_data) ``` and ```python buffer_data = T.allocate([128, 128]) buffer = T.decl_buffer([256, 256], data=buffer_data) ```
