2013-04-22Improve performance of file I/O.Bill Wendling
The fread / fwrite calls were happening for each timer. However, that could be pretty expensive for a large number of timers. Instead, read and write the timers in one call. This gives ~10% speedup in compilation time. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@179990 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-19[ASan] Make init-order checker allow access to already initialized globals.Alexey Samsonov
This change adds ASan runtime option "strict-init-order" (off by default) that makes init-order checker bark if global initializer accesses any global from different translation unit (even if the latter is already initialized). strict init-order checking doesn't play well with, e.g. LLVM registration machineries, and causes issue https://code.google.com/p/address-sanitizer/issues/detail?id=178. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@179843 91177308-0d34-0410-b5e6-96231b3b80d8
