There was a lot of code that was checking "if self.getPlatform() == 'darwin'" which is not correct. I fixed this by adding a: lldbtest.platformIsDarwin() which returns true if the current platform's OS is "macosx", "ios" or "darwin". These three valid darwin are now returned by a static function: lldbtest.getDarwinOSTriples() Fixed up all places that has 'if self.getPlatform() == "darwin":' with "if self.platformIsDarwin()" and all instances of 'if self.getPlatform() != "darwin":' with "if not self.platformIsDarwin()". I also fixed some darwin decorator functions to do the right thing as well. llvm-svn: 233933
