According to him, the compiler built-ins didn't exist back then for m68k which is why the platform-specific functions exist in OpenJDK. They do now, however.

I'll just remove them for m68k and test if that works as expected. If yes, we should change this changeset to do that instead of fixing the platform-specific functions. I have updated the webrev now accordingly and pushed it to [1]. The build and run-test is currently pending (still building), but since libjvm.so already compiled successfully, I am 99% confident the change is correct as is.
