getSystemOrSDKMacOSVersion()

static std::string getSystemOrSDKMacOSVersion ( StringRef  MacOSSDKVersion )

static

Returns the most appropriate macOS target version for the current process.

If the macOS SDK version is the same or earlier than the system version, then the SDK version is returned. Otherwise the system version is returned.

shouldLinkerNotDedup()

static bool shouldLinkerNotDedup ( bool  IsLinkerOnlyAction, const ArgList &  Args  )

static

Pass -no_deduplicate to ld64 under certain conditions:

• Either -O0 or -O1 is explicitly specified
• No -O option is specified and this is a compile+link (implicit -O0)

Also do not add -no_deduplicate when no -O option is specified and this is just a link (we can't imply -O0)
