Enclosed is an explanation of compiler options that we (HAL) used
in our SPEC CPU95 results.

------------------------------------------------------------------------------
C & FORTRAN COMPILER OPTIONS              Remark
------------------------------------------------------------------------------

-dy -dn                            Dynamic or Statically linked libraries

-Kfast                             Make executable run faster using a 
                                   selection options.

-Keval                             Use simple floating-point model.

-Kgs                               Applying optimization of global 
                                   instruction scheduling.

-Kpreload                          Moves load instructions across branch,
                                   when the -Kgs option specified.

-KV8PLUS                           Creates an object program that uses
                                   SPARC V8+ instructions.

-x-                                Applying optimization for inline 
                                   expansion of user-defined external 
                                   procedures having 30 or less 
                                   executable statements.

-x stm_no                          Applying optimization for inline
		                    expansion of user-defined external 
                                   procedure having fewer than specified
				     number of execution statements in the
				    stm_no arguments.

-KGREG                             Uses global registers g2 to g7 during 
				    register allocation phase.

-Kpopt                             Assumes that a memory location referred 
				    by one pointer is referred only by the 
				    pointer; optimizes data referenced by 
				    pointers. 

-K a{1|2|4}                        Specifies, in bytes, the minimum alignment 
				    boundary for external and static variables.

-Xa                                ANSI conformance

-O{0|1|2|3|4}                      specify the level of optimization

-Kauto                             Stack the local variables.

-Kunroll=N(2<=N<=9999)             Unrolls loops until the number of 
                                   statements is less than N.

-Kpreex                            Creates an object program by applying
                                   optimization for advanced evaluation
                                   of invariant expressions. 

-Koffset=N                         Aligns each element of common blocks N
                                   bytes after the previous element.

-X7                                Compiles Fortran source program in
                                   FORTRAN 77.

-fs                                Suppress warning messages.
