New Features in Version A.03.60
Chapter 122
New Features in Version A.03.60
HP aC++ version A.03.60 supports the following new features:
• Debugging of Optimized Code (DOC) in 64-Bit Mode
• Enhancements to C++ Runtime Support Library
• Improved Performance of C++ Virtual Calls at +O4
• Optimizer Tune-Up for PA8800
• Improved C++ Class Array Construction Performance
• Improved Compile Time
• Improved C++ Template Usability
Debugging of Optimized Code (DOC) in 64-Bit Mode
Now it is possible to debug code optimized at +O2 in 64-bit (wide) mode using HP aC++. Use the
compilation option -g +O2 +DD64 to achieve this.
Earlier, DOC was available only in 32-bit (narrow) mode.
Enhancements to C++ Runtime Support Library
In C++, it is possible to make the compiler generate calls to pure virtual functions. When this happens
inadvertently, it can be hard to locate the class to which the pure virtual function belongs. The HP aC++
runtime library has been enhanced to print the name of the containing class when a pure virtual function is
called during execution.
Example:
struct base {
base() { something(this); }
friend void something(base *b){ b->bar(); }
virtual void bar() = 0;
};
struct deri: public base{
void bar(){}
};
