Daga cikin sabbin kayan aikin LLVM 9.0 sami tallafi don cire alamar ci gaban gwaji daga dandamalin RISC-V, Tallafin C ++ na OpenCL.
Wani sabon abu cewa fitacce shine ikon rarraba shirin zuwa ɗakunan ɗorawa da ƙarfi a cikin LLD da aiwatar da »asm goto» ginin da aka yi amfani dashi a cikin lambar kernel ɗin Linux.
