Author: xiaobai Date: Thu Jun 7 12:53:25 2018 New Revision: 334219 URL: http://llvm.org/viewvc/llvm-project?rev=334219&view=rev Log: Check for process_vm_readv using CheckSymbolExists
Instead of checking if code compiles, I think it is a better to check if the symbol exists. This is simpler and should do the same thing.
