2.1.88 --[no_]old_specializations
This option controls the acceptance of old-style template specializations in C++.
Old-style template specializations do not use the template syntax.
Note
The option --old_specializations is provided only as a migration aid for legacy source
code that does not conform to the C++ standard. Its use is not recommended.
Mode
This option is effective only if the source language is C++.
Default
The default is --no_old_specializations.
2.1.89 -Ospace
This option instructs the compiler to perform optimizations to reduce image size at the
expense of a possible increase in execution time.
Use this option if code size is more critical than performance. For example, when the
-Ospace option is selected, large structure copies are done by out-of-line function calls
instead of inline code.
If required, you can compile the time-critical parts of your code with -Otime, and the rest
with -Ospace.
