Clang driver support for linking on Android. llvm-svn: 155541

Add -fsanitize=<sanitizers> argument to driver and frontend, and add -fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the various UBSan checks to be enabled and disabled separately. Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. llvm-svn: 167411

Make sure that we put the rest of the sanitizer libraries on the link line before libstdc++ like we do with ubsan. llvm-svn: 168918

Add -whole-archive around the ASan runtime archive in the link command. This ensures that even though it comes first, we pick up its .o files. Note that if we can use this (or something similar / equivalent) on other platforms, we could potentially remove ReplaceOperatorsNewAndDelete from the ASan runtimes. We should probably do something similar for TSan and MSan as well. llvm-svn: 169328

Currently, with -fsanitize=address, the driver appends libclang_rt.asan.a to the link command. This all works fine when the driver is also responsible for adding -lstdc++ to the link command. But, if -lstdc++ (or libstdc++.a, etc) is passed explicitly to the driver, the ASan runtime will appear in the link command after the standard library, leading to multiple-definition errors for the global 'operator new' and 'operator delete'. Fix this in a painfully simple way, by inserting libclang_rt.asan.a at the start of the link command instead of the end. If we need to do something more clever, we can walk the link command looking for something that resembles libstdc++ and insert libclang_rt.asan.a as late as possible, but the simple solution works for now. llvm-svn: 169310
