At the highest optimization level (+O4), HP's compilers will defer
optimization until link time. The intermediate code object files
(ISOMs in the HP world) exist transparently as normal object files
until the linker encounters them, and can be archived and kept in
libraries if desired. The whole process is fully make-compatible.


We've applied this technology to some large and important programs
here at HP and have seen impressive performance results. See our
recent PLDI paper for more details:
