clang380-import -r294096 variation can complete TARGET_ARCH=powerpc buildworld

[Mark Millard]

After reporting so many examples of what stops buildworld for projects/clang380-import , here is a note about something that can complete. (I've not tested the result.)


After removing -mlongcall usage and changing to avoid building kboot and using WITHOUT_LLDB= an amd64 based projects/clang380-import -r294096 TARGET_ARCH=powerpc buildworld does run to completion.

This was for src.conf being as below (and make.conf being empty):

TO_TYPE=powerpc
#
KERNCONF=GENERICvtsc-NODEBUG
TARGET=powerpc
.if ${.MAKE.LEVEL} == 0
TARGET_ARCH=${TO_TYPE}
.export TARGET_ARCH
.endif
#
WITH_FAST_DEPEND=
WITH_LIBCPLUSPLUS=
WITH_LIB32=
WITH_BOOT=
WITH_CLANG_BOOTSTRAP=
WITH_CLANG=
WITH_CLANG_IS_CC=
WITH_CLANG_FULL=
WITH_CLANG_EXTRAS=
#
# lldb requires missing atomic 8-byte operations for powerpc (non-64)
WITHOUT_LLDB=
#
WITHOUT_GCC_BOOTSTRAP=
WITHOUT_GCC=
WITHOUT_GNUCXX=
#
NO_WERROR=
MALLOC_PRODUCTION=
#
WITHOUT_DEBUG=
WITHOUT_DEBUG_FILES=



And GENERICvtsc-NODEBUG being:

include GENERIC
ident   GENERICvtsc

#nooptions      INVARIANT_SUPPORT       #Extra sanity checks of internal structures, required by INVARIANTS
#nooptions      WITNESS                 #Enable checks to detect deadlocks and cycles
#nooptions      WITNESS_SKIPSPIN        #Don't run witness on spinlocks for speed
#nooptions      MALLOC_DEBUG_MAXZONES   # Separate malloc(9) zones



As I'm no where near getting a matching buildkernel to complete I've not tried to test this buildworld result on a PowerMac that I have access to.
