On the old 32-bit PowerMacs the crash is before Apple's displayed material is replaced and it gets back to Apple's prompt after the error message. The only combination that I've had success with so far for 32-bit powerpc has been system-clang for buildkernel with the in-tree-binutils used. This may not matter much until ifuncs additions are desired --or ever if lld becomes sufficient first. The build failure is for: --- libc.so.7.full --- /usr/local/bin/powerpc-unknown-freebsd13.0-ld: bss-plt forced due to = /usr/obj/powerpcvtsc_xtoolchain-gcc/powerpc.powerpc/usr/src/powerpc.powerp= c/tmp/usr/lib/crtbeginS.o collect2: error: ld returned 1 exit status *** [libc.so.7.full] Error code 1 As for the crashing case, looking at the kernel produced show significant differences in where ABS is used and some other differences. (I do not claim anything like a complete comparison.) Without work on one or both sides, devel/binutils@powerpc does not seem to be an alternative. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
