@targos this patch doesn't land cleanly on v12.4. I'm working on it, but until it is ready, let's have this one as a backup. As a Node.js collaborator, can you run this through the CI with the |

This patches V8 v12.3 for Windows, by fixing multiple compilation errors caused by V8 being a Clang-oriented project. There are various types of errors fixed by this going from changing `using` directives and renaming to overcoming the differences in which Clang and MSVC see templates and metaprogramming. The changes introduced here are strictly meant as a patch only, so they shouldn't be pushed upstream. Refs: targos#13 Refs: targos#14

Could you post a link to the most recent CI run? |
Yes, here it is https://ci.nodejs.org/job/node-test-commit/69900/. It is a resumed build from https://ci.nodejs.org/job/node-test-commit/69886/. From what I see, there are failures with In addition, as seen in one of those 2 builds, but I also saw it previously when testing only Windows, Other than that I see no issues. I had some problems compiling on non-Windows platforms with my fixes, but I resolved that before running those 2 builds. |
