Currently, DebugSymbolsTest.ReqWrapList fails on PPC64LE when Node has been configured with Link Time Optimization (LTO) and using RHEL 8.5 and gcc: ```console $ . /opt/rh/gcc-toolset-11/enable $ export CC='ccache gcc' $ export CXX='ccache g++' $ ./configure --enable-lto $ make -j8 cctest ... 21:52:27 [ RUN ] DebugSymbolsTest.ReqWrapList 21:52:27 ../test/cctest/test_node_postmortem_metadata.cc:203: Failure 21:52:27 Expected equality of these values: 21:52:27 expected 21:52:27 Which is: 140736537072320 21:52:27 calculated 21:52:27 Which is: 1099680328560 21:52:27 [ FAILED ] DebugSymbolsTest.ReqWrapList (43 ms) ``` After looking into this is seems that the compiler is tampering with the `last` variable when compiling with LTO enabled. This commit suggests adding volatile to this variable to prevent the compiler from tampering with it.

Node.js Core Tests
This directory contains code and data used to test the Node.js implementation.
For a detailed guide on how to write tests in this directory, see the guide on writing tests.
On how to run tests in this directory, see the contributing guide.
For the tests to run on Windows, be sure to clone Node.js source code with the
autocrlf git config flag set to true.
Test Directories
| Directory | Runs on CI | Purpose |
|---|---|---|
abort |
Yes | Tests that use --abort-on-uncaught-exception and other situations where we want to test something but avoid generating a core file. |
addons |
Yes | Tests for addon functionality along with some tests that require an addon. |
async-hooks |
Yes | Tests for async_hooks functionality. |
benchmark |
Yes | Test minimal functionality of benchmarks. |
cctest |
Yes | C++ tests that are run as part of the build process. |
code-cache |
No | Tests for a Node.js binary compiled with V8 code cache. |
common |
Common modules shared among many tests. Documentation | |
doctool |
Yes | Tests for the documentation generator. |
es-module |
Yes | Test ESM module loading. |
fixtures |
Test fixtures used in various tests throughout the test suite. | |
internet |
No | Tests that make real outbound network connections. Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections. |
js-native-api |
Yes | Tests for Node.js-agnostic Node-API functionality. |
known_issues |
Yes | Tests reproducing known issues within the system. All tests inside of this directory are expected to fail. If a test doesn't fail on certain platforms, those should be skipped via known_issues.status. |
message |
Yes | Tests for messages that are output for various conditions (console.log, error messages etc.) |
node-api |
Yes | Tests for Node.js-specific Node-API functionality. |
parallel |
Yes | Various tests that are able to be run in parallel. |
pseudo-tty |
Yes | Tests that require stdin/stdout/stderr to be a TTY. |
pummel |
No | Various tests for various modules / system functionality operating under load. |
sequential |
Yes | Various tests that must not run in parallel. |
testpy |
Test configuration utility used by various test suites. | |
tick-processor |
No | Tests for the V8 tick processor integration. The tests are for the logic in lib/internal/v8_prof_processor.js and lib/internal/v8_prof_polyfill.js. The tests confirm that the profile processor packages the correct set of scripts from V8 and introduces the correct platform specific logic. |
v8-updates |
No | Tests for V8 performance integration. |
