Finished benchmarking try commit (52547bf071f62d79d15178ef168074a0a84e30a1): comparison url.

Summary: This benchmark run did not return any significant changes.

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. Please note that if the perf results are neutral, you should likely undo the rollup=never given below by specifying rollup- to bors.

Importantly, though, if the results of this run are non-neutral do not roll this PR up -- it will mask other regressions or improvements in the roll up.

So, I don't think "exposing" the internal logic of arg_count + 1.. is all that great. Could you add a new function on Body, drain_vars_and_temps?
