Detailed Description
This class coordinates the application of a rewrite on a set of IR, providing a way for clients to track mutations and create new operations.
This class serves as a common API for IR mutation between pattern rewrites and non-pattern rewrites, and facilitates the development of shared IR transformation utilities.

◆ inlineBlockBefore() [1/2]

virtual |
Inline the operations of block 'source' into block 'dest' before the given position.
The source block will be deleted and must have no uses. 'argValues' is used to replace the block arguments of 'source'.
If the source block is inserted at the end of the dest block, the dest block must have no successors. Similarly, if the source block is inserted somewhere in the middle (or beginning) of the dest block, the source block must have no successors. Otherwise, the resulting IR would have unreachable operations.

Used to notify the listener that the IR failed to be rewritten because of a match failure, and provide a callback to populate a diagnostic with the reason why the failure occurred.
This method allows for derived rewriters to optionally hook into the reason why a rewrite failed, and display it to users.

This method is used to notify the rewriter that an in-place operation modification is about to happen.
A call to this function must be followed by a call to either finalizeOpModification or cancelOpModification. This is a minor efficiency win (it avoids creating a new operation and removing the old one) but also often allows simpler code in the client.
