HP aC++ compiler version A.06.12 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.
