[mlir] Drop the leading space when printing regions

Authored by Mogball on Jan 15 2022, 5:56 PM.



The leading space that is always printed at the beginning of regions is not consistent with other parts of the printing API. Moreover, this leading space can lead to undesirable assembly formats:

attr-dict-with-keyword $region

Prints as:

// Two spaces between `}` and `{`
attributes {foo}  { ... }

Moreover, the leading space results in the odd generic op format:

"test.op"() ( {...}) : () -> ()

LGTM, but please wait for River to double check that this does not induce new ambiguity.

Also the two examples you give in your description could be handled in the respective places (declarative ASM and generic printer) instead, but I agree that this API contract is more in-line with the other APIs here.
