New Features in Version A.06.12
Version A.06.12 of the HP aC++ compiler supports the following new features:
• +Ofast (-fast) and +Ofaster Options
• Interaction between +Oinit_check and +check=uninit
+Ofast (-fast) and +Ofaster Options
The +Ofast and +Ofaster options now cause the data and text page size to be 1MB
instead of 4MB, for increased performance The +Ofast option no longer implies the
unsafe optimizations +Ointeger_overflow=aggressive and +Olibcalls.
Interaction between +Oinit_check and +check=uninit
When +Oinit_check and +check=uninit are used together, warnings will still be
generated at compile time for potentially uninitialized variables, but they will not be
automatically initialized by the compiler, so that lack of initialization can be detected
at runtime.
