[Lldb-commits] [PATCH] [linux] Use cmake to detect support process_vm_readv (bug #23918)

[Pavel Labath]

Hi ovyalov, Eugene.Zelenko,

Some old linux versions do not have process_vm_readv function defined. Even older versions do not
have even the __NR_process_vm_readv syscall number. We use cmake to detect these situations and
fallback appropriately: in the first case, we can issue the syscall manually, while it the latter
case, we need to drop fast memory read support completely.
