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=3D an amd64 based projects/clang380-import -r294096 =
TARGET_ARCH=3Dpowerpc buildworld does run to completion.
This was for src.conf being as below (and make.conf being empty):
TO_TYPE=3Dpowerpc
#
KERNCONF=3DGENERICvtsc-NODEBUG
TARGET=3Dpowerpc
.if ${.MAKE.LEVEL} =3D=3D 0
TARGET_ARCH=3D${TO_TYPE}
.export TARGET_ARCH
.endif
#
WITH_FAST_DEPEND=3D
WITH_LIBCPLUSPLUS=3D
WITH_LIB32=3D
WITH_BOOT=3D
WITH_CLANG_BOOTSTRAP=3D
WITH_CLANG=3D
WITH_CLANG_IS_CC=3D
WITH_CLANG_FULL=3D
WITH_CLANG_EXTRAS=3D
#
# lldb requires missing atomic 8-byte operations for powerpc (non-64)
WITHOUT_LLDB=3D
#
WITHOUT_GCC_BOOTSTRAP=3D
WITHOUT_GCC=3D
WITHOUT_GNUCXX=3D
#
NO_WERROR=3D
MALLOC_PRODUCTION=3D
#
WITHOUT_DEBUG=3D
WITHOUT_DEBUG_FILES=3D
And GENERICvtsc-NODEBUG being:
include GENERIC
ident GENERICvtsc
nooptions PS3 #Sony Playstation 3 =
HACK!!! to allow sc
options DDB # HACK!!! to dump early crash =
info (but 11.0-CURRENT already has it)
options GDB # HACK!!! ...
#options VERBOSE_SYSINIT
#options BOOTVERBOSE=3D1
#options BOOTHOWTO=3DRB_VERBOSE
#options KTR
#options KTR_MASK=3DKTR_TRAP
#options KTR_CPUMASK=3D0xF
#options KTR_VERBOSE
# HACK!!! to allow sc for 2560x1440 display on Radeon X1950 that vt =
historically mishandled during booting
device sc
#device kbdmux # HACK: already listed by vt
options SC_OFWFB # OFW frame buffer
options SC_DFLT_FONT # compile font in
makeoptions SC_DFLT_FONT=3Dcp437
# Disable extra checking typically used for FreeBSD 11.0-CURRENT:
#nooptions DEADLKRES #Enable the deadlock resolver
#nooptions INVARIANTS #Enable calls of extra sanity =
checking
#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.
