/cc @gengjiawen related to nodejs/node-v8#161

Yeap. Also msvc only report one error, I will give it a try.

BTW, we need to cherrypick v8/v8@4ece106.

cjihrig · 2020-07-23T00:10:26Z

@targos, since --experimental-wasm-bigint is no longer required for the WASI API, would you like to pull cjihrig@dbff5bc into this upgrade, or would you prefer me to PR it separately after the upgrade lands?

gengjiawen · 2020-08-23T15:57:52Z

In case you want patch code for windows, you can get first two commit in https://github.com/gengjiawen/node/commits/v8-8.5-hack before nodejs/gyp-next#60 get fixed. @targos

bricss · 2020-09-04T23:09:07Z

Is there any chance that it may get into Node 14 or 15? 😶

Major V8 updates are usually API/ABI incompatible with previous versions. This commit adapts NODE_MODULE_VERSION for V8 8.5. Refs: https://github.com/nodejs/CTC/blob/master/meetings/2016-09-28.md

Patch V8 (compiler/js-heap-broker.cc) to remove the use of an optional property, which is a fairly new C++ feature, since that requires a newer XCode version than the minimum requirement in BUILDING.md and thus breaks CI.

Testing something: https://ci.nodejs.org/job/node-test-commit-arm-fanned/16538/

gengjiawen · 2020-09-26T15:42:00Z

@targos I believe I have find the root cause through the generated mk file. It looks like the assembly file processed both on host and target. So we should limit it only on target (<(V8_ROOT)/src/heap/base/asm/arm/push_registers_asm.cc are valid assembly only for arm, that's why gcc failed on v8_base_without_compiler.host.mk) .

Below is build by removing it in v8_base_without_compiler.host.mk file manully.

Maybe only something like (not quite sure about the syntax)

              ['_toolset == "target" and v8_current_cpu=="arm"', {
                'sources': [
                  '<(V8_ROOT)/src/heap/base/asm/arm/push_registers_asm.cc'
                ],
              }],

targos · 2020-09-27T08:48:10Z

I don't know... My condition seems right. I looked at the Jenkins logs and for cross-compiler-ubuntu1804-armv7-gcc-6, host_arch is ia32 and target_arch is arm, so unless I'm missing something with priority of operators in Python, it should pick up the ia32 file.

targos · 2020-09-27T09:06:12Z

So, with the log I added, we can see that the variables have the following values:

'host_arch': 'ia32'
'target_arch': 'arm'
'_toolset': 'target'

There's no other log where _toolset is host 🤔. I'm trying one last thing.

CI: https://ci.nodejs.org/job/node-test-commit-arm-fanned/16551/

Edit: doesn't work. I'm out of ideas.

mmarchini · 2020-09-27T09:11:16Z

@targos if you want to test locally, you can also try https://github.com/mmarchini/node-arm-cross-builder

mmarchini · 2020-09-27T09:13:44Z

_toolset being always target seems like either a bug, or we're using the wrong variable to test the current toolset.

gengjiawen · 2020-09-27T14:12:58Z

_toolset being always target seems like either a bug, or we're using the wrong variable to test the current toolset.

_toolset seems to be 'target' all the time from what I test. Maybe a bug in gyp.

Looks the generated mk file toolset is set correctly. Where _toolset is set in gyp ?

  1 # This file is generated by gyp; do not edit.
  2 
  3 TOOLSET := host
  4 TARGET := v8_base_without_compiler

sxa · 2020-09-29T11:32:10Z

I realise I'm somewhat "drive-by commenting" here, but is there a reason why we still have to cross compile for arm32? There's some reasonably quick stuff out there now (e.g. Raspberry Pi4 or ODROID-XU4 which I use) and if those could be used to build natively in a reasonable amount of time and don't exhibit the same problems it might be worth switching.

gengjiawen · 2020-09-29T11:34:52Z

Tinker v8.gyp like will have '_toolset': 'host' in the log, but I still get v8_base_without_compiler.host.mk have $(obj).host/$(TARGET)/deps/v8/src/heap/base/asm/ia32/push_registers_asm.o, not sure why.

    {
      'target_name': 'v8_cppgc_shared',
      'type': 'none',
      # 'conditions': [
      #   ['want_separate_host_toolset', {
      #     'toolsets': ['host', 'target'],
      #   }],
      # ],
      'toolsets': ['host', 'target']

gengjiawen · 2020-09-29T11:36:13Z

@sxa It's already tier 1 in build. I suppose even if we want to change it. It will be a much more bigger issue.

Context: nodejs/TSC#931 (comment).

sxa · 2020-09-29T11:39:35Z

For completeness, link to a proposed switch to building natively that went stale nodejs/build#1851

gengjiawen · 2020-09-29T11:55:40Z

@targos I think I find the fix, not sure the reason why. I tested in the docker, works fine, you can test it in Jenkins.

Change the part like this

    {
      'target_name': 'v8_cppgc_shared',
      'type': 'none',
      # 'conditions': [
      #   ['want_separate_host_toolset', {
      #     'toolsets': ['host', 'target'],
      #   }],
      # ],
      'toolsets': ['host', 'target'],
      'direct_dependent_settings': {
        'sources': [
          '<(V8_ROOT)/src/heap/base/stack.cc',
          '<(V8_ROOT)/src/heap/base/stack.h',
        ],
        'conditions': [
          ['clang or OS!="win"', {
            'conditions': [
              ['_toolset=="target" and target_arch == "arm"', {
                'sources': [
                  '<(V8_ROOT)/src/heap/base/asm/arm/push_registers_asm.cc',
                ],
              }],
              ['_toolset == "target" and target_arch=="arm64"', {
                'sources': [
                  '<(V8_ROOT)/src/heap/base/asm/arm64/push_registers_asm.cc',
                ],
              }],
            ]
          // other omitted.

@gengjiawen with the change you propose, does it still work for regular compilation, for example x64?

Not test it yet, give me a second.

@targos Looks like still works (Note: in my snippet I only show two cpus).

PS: the full build without ccache is really long.
