powerpc64-gcc unable to compile clang 3.8.0 from clang380-import -r294609 via buildworld

[Mark Millard]

I tried a buildworld that included building clang and lldb based on using powerpc64-xtoolchain-gcc/powerpc64-gcc as a cross compiler. It failed, see below. This might indicate a more general gcc 5.x vs. clang 3.8.0 source code mismatch. This was my first try. This could have been true for some time.

(not the only error reported for CFG.cpp’s compile, I just listed the first).

I do not know if the -std=gnu++11 that is automatically used is causing variations in the language definition in use or not.



I do this sort of thing with 11.0-CURRENT now and have been for a long time, including building clang 3.7.1 and its lldb via powerpc64-gcc in more recent times. But powerpc64-gcc has historically rejected the clang extras so I’ve used WITHOUT_CLANG_EXTRAS= historically.



Some context notes:

Empty make.conf via __MAKE_CONF use.
