New description:
There should be a flag `+RTS -foo` that prints info including:
* The version of GHC used to compile the program
* The sort of RTS linked against
* What (canonicalised) platform it was built for, i.e., powerpc-apple-
darwin8.10.0
There should also be a flag that can be given to the compiler that prints
info including:
* Whether it has a NCG
* Whether or not it is registerised
* Whether it supports ghci/ghc -e
* What RTSs it has
* Whether it supports SMP
Ideally this would all be easily machine-parseable.
Comment:
machine-parseable: would one-liner's do? For example:
compiled_with: ghc-6.4.1
platform: i386-unknown-mingw32
rts_ways: t, p (use build system codes)
registerised: YES (or 1)
supports_NCG: YES (or 1)
supports_SMP: YES (or 1)
The idea is that all this can go directly from compiler/Makefile into
Config.hs into the options. Doesn't need to be after +RTS; might be an
argument to ghc --version (no arg means as before; arg with parameter you
want returns value like sysctl -n var on Darwin).
