And we should be aiming to make the GCC build, test and install process simpler: install to a staging directory during build, use the built-in relocatability in building target libraries and running testsuites rather than needing to pass long sequences of -B etc. options at those stages, and just copy the staging directory for final installation. (It's nasty that not just the build systems of the various toolchain components but upstream DejaGnu itself has hardcoded information about how bits of the tools can locate each other in their build directories. Nothing should ever need to know that; the staging install code should just put things so that they can find each other automatically.) -- Joseph S. Myers jos...@codesourcery.com
