I think the best way is listing of the largest possible number of
architectures, at least, all supported in Debian.
I have no idea how macros with CPU names are used. But macros with
bitness, ARCH_CPU_32_BITS and ARCH_CPU_64_BITS, are used for
optimizations in Telegram/SourceFiles/ui/animation.h file. I took info
about bitness from Debian site or Wikipedia, I hope it doesn't contain a
mistake.
I prepared this patch with such list. What do you make of it? Maybe
there is a better solution?
