Add a new watchdog timer interface. The interface does not permit handling timeouts, so it's only really useful if you're going to crash anyways. Use it in the pretty stack trace printer to kill the compiler if we hang while printing the stack trace. llvm-svn: 177962

IWYU for llvm-config.h in llvm, additions. See r331124 for how I made a list of files missing the include. I then ran this Python script: for f in open('filelist.txt'): f = f.strip() fl = open(f).readlines() found = False for i in xrange(len(fl)): p = '#include "llvm/' if not fl[i].startswith(p): continue if fl[i][len(p):] > 'Config': fl.insert(i, '#include "llvm/Config/llvm-config.h"\n') found = True break if not found: print 'not found', f else: open(f, 'w').write(''.join(fl)) and then looked through everything with `svn diff | diffstat -l | xargs -n 1000 gvim -p` and tried to fix include ordering and whatnot. No intended behavior change. llvm-svn: 331184

s/LLVM_ON_WIN32/_WIN32/, llvm LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the default macro instead of a reinvented one. See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev. No intended behavior change. This moves over all uses of the macro, but doesn't remove the definition of it in (llvm-)config.h yet. llvm-svn: 331127
