Leko · 2017-12-11T04:20:31Z

This PR closes #17571

I added --perf-prof and --perf-basic-prof to whitelist.

Please help me in solving error.
I got an error when run with --perf-prof in NODE_OPTIONS

$ NODE_OPTIONS=--perf-prof ./node


#
# Fatal error in , line 0
# unimplemented code
#
Illegal instruction: 4

When run with --perf-basic-prof, it works fine.

$ NODE_OPTIONS=--perf-basic-prof ./node
> // It is OK

What means of unimplemented code ?
What should I do ?

joyeecheung · 2017-12-11T09:11:13Z

I think you were running it on MacOS? PerfJitLogger is only implemented in Linux.

Leko · 2017-12-11T09:21:45Z

Thank you for your help @joyeecheung.

I think you were running it on MacOS?

Yes it is.
I'll use Linux in this PR.

I have a new question.
Should I avoid to test about perf-prof ?
It might be fail not Linux environment.

@bnoordhuis Thank you for review !
I moved them under v8 options.

perf-prof works in Linux only. For example, it not works in MacOS.

I use common.isLinux like:

if (common.isLinux) {
  expect('--perf-prof', 'B\n');
}

It is correct ?

This must be with --perf-basic-prof (because --perf-prof is only tried on Linux).

@bnoordhuis Thanks, but not until I'm back in the office second week of January. Perhaps someone else in @nodejs/platform-ppc and/or @nodejs/platform-s390 could try in the meantime?

common.isLinux does not work correctly?

https://github.com/Leko/node/blob/b97987ad57f2794d3d0e355c47bd8fc3796a8ea2/test/parallel/test-cli-node-options.js#L29-L32

I think --perf-prof should not evaluate in Linux one, PPC Linux and Windows.

if (common.isLinux && !common.isLinuxPPCBE && !{TODO}) {

What is the variable corresponding to test/linux-one and test/windows-fanned?

joyeecheung · 2017-12-27T04:00:11Z

@Leko Maybe you can try whitelisting instead? I think it should be common.isLinux && ['arm', 'x64', 'ia32', 'mips'].includes(process.arch).
