Examples

The following example compiles and links in the same step.

example% CC -xipo -xO4 -o prog  part1.cc part2.cc part3.cc

The optimizer performs crossfile inlining across all three source files. This is done in the final link step, so the compilation of the source files need not all take place in a single compilation and could be over a number of separate compilations, each specifying the -xipo option.

The following example compiles and links in separate steps.

example% CC -xipo -xO4 -c part1.cc part2.cc
example% CC -xipo -xO4 -c part3.cc
example% CC -xipo -xO4 -o prog part1.o part2.o part3.o

The object files created in the compile steps have additional analysis information compiled within them to permit crossfile optimizations to take place at the link step.
