Precompiled Header (PCH) Feature Fully Supported under -AA
Precompiled Header (PCH) is now fully supported with -AA option. That means PCH feature can be used
with STL (Standard Template Library).
Debugging Optimized Code (DOC)
Debugging of optimized code (at optimization level +O2) is more robust now. Debugging of template
functions is much improved.
+O[no]clone Option
This option provides user control to turn on [off] the cloning feature of the optimizer. This option is
primarily for users who may see a lot of cloning adversely affecting the performance of their code, and want
more control over cloning.
