[v12.x] src: make --use-largepages a runtime option by gabrielschulhof · Pull Request #31063 · nodejs/node

gabrielschulhof · 2019-12-23T06:23:30Z

Moves the option that instructs Node.js to-remap its static code to
large pages from a configure-time option to a runtime option. This
should make it easy to assess the performance impact of such a change
without having to custom-build.

This was the only conflict. It was expecting to remove auto munmap_on_return = OnScopeLeave(...); and not OnScopeLeave munmap_on_return(...);

configure.py

Re-introduce the build-time option as a no-op in order to retain backward compatibility for LTS purposes. Re: nodejs#31063 (review)

@addaleax IINM there's still some buffer-freeing-related flakiness: https://ci.nodejs.org/job/node-test-commit-plinux/29916/nodes=centos7-ppcle/console

Edit: Whoops 🙂 Wrong PR 🙂
