Topic: wasmtime / PR #5740 Make `DataFlowGraph::blocks` public

Wasmtime GitHub notifications bot (Feb 07 2023 at 22:07):

elliottt opened PR #5740 from trevor/pub-blocks to main:

Similar to when we exposed the DataFlowGraph::insts field through a restrictive newtype, expose DataFlowGraph::blocks through an interfac that allows a restrictive set of operations. This field being public now allows us to avoid a rematch in ssa construction, and simplifies the implementation of adding a block argument to a block referenced by a br_table instruction.

Others may disagree with me here but I don't think there's value in the num_block_params interface. Getting the slice of block params doesn't cost any more than getting its length (I think it adds 4 to a pointer it already computed to get the length, and returns the adjusted pointer along with the length) so I don't think the extra API clutter is worth its weight.

We can leave DataFlowGraph::num_block_params so we aren't forcing people to change their calls for no reason, but I'd rather not add this function in this new spot.

Bikeshed: Since make_block is already accessed through a field named "blocks", how about a name that doesn't have "block" in it? I was tempted to suggest blocks.new() but that's not exactly idiomatic, so maybe just blocks.add()?
