Author: jhb Date: Mon Oct 14 21:22:42 2019 New Revision: 353523 URL: https://svnweb.freebsd.org/changeset/base/353523 Log: Disconnect powerpc from the default tinderbox for now. The wrong toolchain was set in MAKE_PARAMS_powerpc, however, there are some other issues preventing powerpc from building in tinderbox: 1) There is no powerpc-gcc and powerpc-xtoolchain-gcc port that provides an external 32-bit powerpc GCC toolchain. 2) On other targets, the same toolchain can build all of the architectures for a given target. MIPS achieves this by always setting -mabi and -EB/-EL explicitly instead of relying on the compiler's default architecture. PowerPC might be able to do the same thing, but as of today, powerpc-gcc would be required for powerpc and powerpcspe and powerpc64-gcc would be required for powerpc64. Our existing logic for make universe does not permit per-MACHINE_ARCH toolchains. I tried hacking TARGETS_powerpc to only include powerpc64 when powerpc64-gcc was present, and while that skipped the 32-bit worlds, it tried to build all the kernels.
