Fixed oe-core ml
Naveen:
Looks like the latest version of TBB does not build correctly for PPC
machine targets (qemuppc for sure), it builds for qemuppc64
The failure seems to be the handling of __TBB_machine_fetch4()
definition below, particularly the ITT_ARCH check for PPC64 but not PPC.
/srv/nvme/yocto/hardknott/builds/tbb/tmp/work/ppc7400-poky-linux/tbb/2021.2.0-r0/git/src/tbb/tools_api/ittnotify_config.h:338:12:
error: '__TBB_machine_fetchadd4' was not declared in this scope
338 | return __TBB_machine_fetchadd4(ptr, 1) + 1L;
| ^~~~~~~~~~~~~~~~~~~~~~~
Is TBB supported for PPC?
Thanks
Sau!
