Intel® C++ Compiler 16.0 User and Reference Guide
Instructs the compiler to analyze the program to determine if there are 64-bit pointers that can be safely shrunk to 32-bit pointers.
Only available on Intel® 64 architecture
Linux and OS X: | -auto-p32 |
Windows: | None |
None
OFF |
The optimization is not performed. |
This option instructs the compiler to analyze and transform the program so that 64-bit pointers are shrunk to 32-bit pointers, wherever it is legal and safe to do so.
On OS X* systems, you must also specify option -no-pie for the optimization to occur.
For this option to be effective, the compiler must be able to optimize using the -ipo option and it must be able to analyze all library calls or external calls the program makes. This option has no effect unless you specify setting SSE3 or higher for option -x.
The application cannot exceed a 32-bit address space; otherwise, unpredictable results can occur.
