Reland "[include] Split out v8.h" This is a reland of d1b27019d3bf86360ea838c317f8505fac6d3a7e Fixes include: Adding missing file to bazel build Forward-declaring classing before friend-classing them to fix win/gcc Add missing v8-isolate.h include for vtune builds Original change's description: > [include] Split out v8.h > > This moves every single class/function out of include/v8.h into a > separate header in include/, which v8.h then includes so that > externally nothing appears to have changed. > > Every include of v8.h from inside v8 has been changed to a more > fine-grained include. > > Previously inline functions defined at the bottom of v8.h would call > private non-inline functions in the V8 class. Since that class is now > in v8-initialization.h and is rarely included (as that would create > dependency cycles), this is not possible and so those methods have been > moved out of the V8 class into the namespace v8::api_internal. > > None of the previous files in include/ now #include v8.h, which means > if embedders were relying on this transitive dependency then it will > give compile failures. > > v8-inspector.h does depend on v8-scripts.h for the time being to ensure > that Chrome continue to compile but that change will be reverted once > those transitive #includes in chrome are changed to include it directly. > > Full design: > https://docs.google.com/document/d/1rTD--I8hCAr-Rho1WTumZzFKaDpEp0IJ8ejZtk4nJdA/edit?usp=sharing > > Bug: v8:11965 > Change-Id: I53b84b29581632710edc80eb11f819c2097a2877 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3097448 > Reviewed-by: Yang Guo <yangguo@chromium.org> > Reviewed-by: Camillo Bruni <cbruni@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Commit-Queue: Dan Elphick <delphick@chromium.org> > Cr-Commit-Position: refs/heads/main@{#76424} Cq-Include-Trybots: luci.v8.try:v8_linux_vtunejit Bug: v8:11965 Change-Id: I99f5d3a73bf8fe25b650adfaf9567dc4e44a09e6 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3113629 Reviewed-by: Leszek Swirski <leszeks@chromium.org> Reviewed-by: Camillo Bruni <cbruni@chromium.org> Reviewed-by: Michael Lippautz <mlippautz@chromium.org> Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Simon Zünd <szuend@chromium.org> Commit-Queue: Dan Elphick <delphick@chromium.org> Cr-Commit-Position: refs/heads/main@{#76460}
