-xcrossfile[=n]

(SPARC) Enables optimization and inlining across source files. If specified, n can be 0 or 1.

Normally the scope of the compiler's analysis is limited to each separate file on the command line. For example, -xO4's automatic inlining is limited to subprograms defined and referenced within the same source file.

With -xcrossfile, the compiler analyzes all the files named on the command line as if they had been concatenated into a single source file. -xcrossfile is only effective when used with -xO4 or -xO5.

The files produced from this compilation are interdependent due to possible inlining, and must be used as a unit when they are linked into a program. If any one routine is changed and the files recompiled, they must all be recompiled. As a result, using this option affects the construction of makefiles.

The default is -xcrossfile=0, and no cross-file optimizations are performed. -xcrossfile is equivalent to -xcrossfile=1.
