I'd like to include three different flavours of my HBase package, with these combinations of optimisation and profiling:
release: optimised (with -O -fvia-C) profiling: optimised and profiled quick: neither
The release and profiling flavours take forever to compile, so it's useful to have a "quick" flavour to speed up the development cycle. The trouble is, any Haskell program using the release flavour of HBase also compiles very slowly, even if it itself does not use -O. If nothing else, this may be due to the huge interface file for the root import:
$ ls -Al HBase.*hi -rw-r--r-- 1 ashley ashley 2117554 May 28 04:04 HBase.hi -rw-r--r-- 1 ashley ashley 2119865 May 28 08:15 HBase.p_hi -rw-r--r-- 1 ashley ashley 72669 May 28 16:20 HBase.q_hi
Wow :-) There is some ancient support for "user-ways" in the compiler, but as far as I know it doesn't currently work. The only ways that the compiler knows about are the built-in ones (profiling, ticky, parallel etc.). I think the best way to achieve what you want is to have two completely separate packages, say hbase and hbase_q. The hbase package can have profiling support, but the hbase_q package need not.
