deps: update V8 to 14.1

[targos]

This should replace #58491

Still blocked at least on nodejs/build#4083

V8 CI is also broken because --always-turbofan flag was removed. I tried to fix it in canary with ab7d369, but then test/v8-updates/test-linux-perf-logger.js fails because the functions don't get optimized: https://ci.nodejs.org/job/node-test-commit-v8-linux/6742/nodes=benchmark-ubuntu2204-intel-64,v8test=v8test/console

Notable changes since 13.7:

• JSON.stringify performance improvements
• Uint8Array to/from base64 and hex

@nodejs/platform-ppc @nodejs/platform-s390 we quickly get a compiler error:

This might be a gcc issue. I'm working on a patch to make tools/make-v8.sh compatible with clang -- I'm testing with it on top of the branch for this PR (it didn't work with main because we need patches to V8's build dep which should be okay with V8 14.1): https://ci.nodejs.org/job/richardlau-node-test-commit-v8-linux/732/

[miladfarca]

We no longer maintain gcc builds for RHEL on ppc64/s390x and builds now are using Clang. This patch which enables it on said platforms should already be part of 14.1: https://crrev.com/c/6705431

FWIW https://ci.nodejs.org/job/node-test-commit-linuxone/51470/ (also with clang-19) passed.

[targos]

Is it possible that it's using the wrong version of the C++ standard library? Both errors are related to C++20 features.

[richardlau]

Is it possible that it's using the wrong version of the C++ standard library? Both errors are related to C++20 features.

Quite possibly. Node.js built successfully with clang 19 for the equivalent platform: https://ci.nodejs.org/job/node-test-commit-linuxone/51470/

The IBM team that maintains the upstream Linux ppc64le and s390x ports build V8 with use_custom_libcxx = true. We can't currently do that with the V8 CI in Node.js unless we pull in more DEPS for V8: https://ci.nodejs.org/job/richardlau-node-test-commit-v8-linux/734/nodes=rhel8-s390x,v8test=v8test/console

[richardlau]

Is it possible that it's using the wrong version of the C++ standard library? Both errors are related to C++20 features.

So I compared command lines for compiling src/builtins/generate-bytecodes-builtins-list.cc in the (working) Node.js build and the (failing) V8 CI with clang 19 and it appears that the difference may be that the V8 build is passing --target=s390x-unknown-linux-gnu on the command line whereas we don't pass any --target value for the Node.js build.

Note that the search paths point to the gcc-toolset-14 directories. Compare with passing --target=s390x-unknown-linux-gnu, which is searching the includes for the default (gcc 8):

I think the target is used to search for a config, e.g. in the default case it finds a configuration file /etc/clang/s390x-redhat-linux-gnu-clang++.cfg but nothing for when --target=s390x-unknown-linux-gnu is passed in. In /etc/clang:

[iojs@test-ibm-rhel8-s390x-3 ~]$ ls -al /etc/clang

[iojs@test-ibm-rhel8-s390x-3 ~]$

and FWIW

[iojs@test-ibm-rhel8-s390x-3 ~]$ cat /etc/clang/s390x-redhat-linux-gnu-clang++.cfg
 --gcc-triple=s390x-redhat-linux -gdwarf-4 -g0 --gcc-install-dir=/opt/rh/gcc-toolset-14/root//usr/lib/gcc/s390x-redhat-linux/14
[iojs@test-ibm-rhel8-s390x-3 ~]$

I could try creating a s390x-unknown-linux-gnu-clang++.cfg configuration file with the same contents as the existing /etc/clang/s390x-redhat-linux-gnu-clang++.cfg.

[richardlau]

wrt. the V8 CI on Linux ppc64le and s390x. I have opened #59893 and nodejs/build#4153 which combined with this PR has enabled the V8 CI to build with clang. I also updated the Jenkins job to erase the --target parameter to avoid the vendor mismatch in the target triplet.

This test CI is a combination of the above changes and this PR: https://ci.nodejs.org/job/richardlau-node-test-commit-v8-linux/746/
It passed on Linux s390x.
On Linux ppc64le it compiled successfully but fails two tests (cc @nodejs/platform-ppc ). I don't know if that a missing fix, or due to using gcc atomics instead of V8's custom libcxx.
