Option |
Meaning |
-fast |
This option is a macro that you can effectively use as a starting
point for tuning an executable for maximum run-time performance.
|
-m32|64 |
Specifies the memory model for the compiled binary object. |
-mt |
Indicates compilation and linking for multithreaded code. |
-xarch |
Specifies the target architecture instruction set (ISA). |
-xautopar |
Turns on automatic parallelization for multiple processors. |
-xexplicitpar |
Parallelizes the loops that are specified. |
-xhwcprof |
Enables compiler support for hardware counter-based profiling. |
-xipo |
Performs interprocedural optimizations. |
-xlinkopt |
Performs link-time optimizations on relocatable object files. |
-xmemalign |
Specifies the maximum assumed memory alignment and the behavior of
misaligned data accesses.
|
-xopenmp |
Enable explicit parallelization with OpenMP directives. |
-xpagesize |
Set the preferred page size for the stack and the heap. |
-xpagesize_heap |
Set the preferred page size for the heap. |
-xpagesize_stack |
Set the preferred page size for the stack. |
-xparallel |
Parallelizes loops both automatically (by the compiler) and
explicitly (as specified by the programmer).
|
-xpg |
Compiles for profiling with the gprof profiler. |
-xprofile |
Collects or optimizes with runtime profiling data. |
-xvector |
Enables automatic generation of calls to the vector library and/or
the generation of the SIMD (Single Instruction Multiple Data) instructions.
