-Zlp

(SPARC) Prepares object files for the loop profiler, looptool. The looptool(1) utility can then be run to generate loop statistics about the program. Use this option with -xdepend; if -xdepend is not explicitly or implicitly specified, turns on -xdepend and issues a warning. If optimization is not at -xO3 or higher, optimization is raised to -xO3 and a warning is issued. Generally, this option is used with one of the loop parallelization options: -xexplicitpar, -xautopar, or -xparallel.

The Sun WorkShop includes the license required to use the MPC options. To get faster code, this option requires a multiprocessor system. On a single-processor system, the generated code usually runs slower.

If you compile and link in separate steps, and you compile with -Zlp, then be sure to link with -Zlp.

If you compile one subprogram with -Zlp, you need not compile all subprograms of that program with -Zlp. However, you get loop information only for the files compiled with -Zlp, and no indication that the program includes other files.
