OK I've finished my pass through this uber-set. I've given it a fairly good tyre-kicking on ARM (guest and hosts) with RISU so I think you can have a: Tested-by: Alex Bennée <alex.ben...@linaro.org> for the ARM bits at least. > > Changes since v3: > * PPC host patches have been properly annotated for cpu revision, > - cnttz[wd] are power9 inventions, > - cntpop[wd] are power7 inventions. > > * X86 host checks the correct cpuid bit for lzcnt. > > * Generic TCG has significant changes to enable "interesting" > combinations of constraints for X86 host bsr/bsf and to some > extent lzcnt/tzcnt. > > * Opcode for ctpop.
