Sorry, something went wrong.
Original commit message:
[coverage] Fix coverage with default arguments
In the presence of default arguments, the body of the function gets
wrapped into another block. This caused our trailing-range-after-return
optimization to not apply, because the wrapper block had no source
range assigned. This CL correctly assignes a source range to that block,
which allows already present code to handle it correctly.
Note that this is not a real coverage bug; we've just been reporting
whitespace as uncovered. We're fixing it for consistency.

@mhdawson in the rebase, it seems like something in the nodejs:v12.x-staging branch, perhaps something else we backported, removes the code-coverage-block-async.js test file. I didn't think this was the end of the world, as we have coverage in code-coverage-block.js. |
