[CMake][WPE] WebKitTestRunner shouldn't link object files of JavaScriptCore and WebCore

[Fujii Hironori]

In WPE builds, bin/WebKitTestRunner depends on a lot of object files of JSC and WebCore.

./Tools/Scripts/build-webkit --wpe --release |& tee build.log
ninja -C WebKitBuild/WPE/Release -t query bin/WebKitTestRunner

On the other hand, GTK doesn't.

./Tools/Scripts/build-webkit --gtk --release --generate-project-only
ninja -C WebKitBuild/GTK/Release -t query bin/WebKitTestRunner

WIP patch

This WIP patch fixes the dependency by reverting the part of Bug 222860. But it can't compile.

This broke builds with LTO enabled.

I will try to get the linker error message to paste here.

I haven't tried LTO build. How did you build? Which port? 
Can I use build-webkit for LTO build, like "build-webkit --gtk --release --lto-mode=full"?

AFAIR the “--lto-mode=” flag does not work well with the CMake ports.
This is the easiest way to reproduce:

  CFLAGS=-flto CXXFLAGS=-flto LDFLAGS=-flto \
      build-webkit --gtk [--release | --debug]

[Fujii Hironori]

Thank you. Unfortunately, My PC doesn't have enough RAM to finish the LTO linking. 😥

[Michael Catanzaro]

It looks like something is wrong specifically with inline assembler after this change? The functions generated from inline assembler are missing at link time?

Would you be interested in investigating further if we find a way to get you remote access to beefier hardware?

[Fujii Hironori]

This issue isn't urgent. I'll revisit it after buying a new machine.

[Fujii Hironori]

See bug#249368 for another LTO problem.
