Chapter 1 New and Changed Features

+objdebug leaves debugging information in the object files rather than copying it to the executable file.

NOTE: You must install the latest linker patch (PHSS_16841) or its successor for this option to work. Without this patch, the option is ignored.

+W suppresses warnings.

+We changes warnings to errors.

+Ww enables warnings that would otherwise not be enabled.

+Olevel=name lowers the optimization level for the named functions.

+Oreusedir=directory reduces link time by saving and reusing object files in directory rather than recompiling them from intermediate object files.

+O[no]promote_indirect_calls promotes indirect calls to direct calls to improve performance.
