Maybe a note here about any arguments accepted by deps/v8/tools/tickprocessor.js would do in case V8 removes that in the future?

I think we should note in https://github.com/nodejs/node/blob/master/doc/api/cli.md#--prof-process and https://github.com/nodejs/node/blob/master/doc/node.1 about the processing of subsequent options.

@richardlau Would a follow-up PR be okay? I’d also like to make --prof-process --help work, and it would be good to be able to refer to that (I don’t think it has ever worked in Node.js)

Can we fast-track this and getting it into a release asap?

@mcollina Are you asking for a release sooner than usual (i.e. this week instead of the next one)?

@mcollina

If possible, yes. If no one is available to do it, it's not a big deal (next week is also ok). A significant number of flamegraph tools (not just clinic) are broken because of this.

I pushed a commit to skip the test on AIX completely; not sure why it’s failing there. (/cc @nodejs/platform-aix)

There's this comment in the tick-processor tests:

node/test/tick-processor/test-tick-processor-unknown.js

Lines 4 to 10 in 19c0620

// TODO(mhdawson) Currently the test-tick-processor functionality in V8
// depends on addresses being smaller than a full 64 bits. AIX supports
// the full 64 bits and the result is that it does not process the
// addresses correctly and runs out of memory
// Disabling until we get a fix upstreamed into V8
if (common.isAIX)
common.skip('AIX address range too big for scripts.');
