The (Interactive) Glasgow Haskell Compiler -- version 5.02.3
Nice. :-)
NOTE: object files created by this vesrion of GHC may be incompatible with object files created by older versions of GHC, so be sure to recompile any pre-compiled libraries you may have lying around.
produce (perhaps longer if optimisation is on). So it pays to compile
This made me think about using *.o-files in GHCi generated w/ 'ghc -O2'. My GHCi (currently 5.00.2) states: --- snip --- warning: -O conflicts with --interactive; -O turned off. --- snap --- if I pass -O2 to ghci. Additionally, I recall some core-dumps or having ghci sometimes report missing symbols if using some modules compiled w/ optimization. So, is GHCi supposed to work w/ optimized modules after all? The documentation merely suggests, this might be possible: --- snip --- Why should we want to run compiled code? Well, compiled code is roughly 10x faster than interpreted code, but takes about 2x longer to the parts of a program that aren't changing very often, and use the interpreter for the code being actively developed. --- snap --- Thanks -- Till -- e-mail: reverse(net dot doerges at till) | ENCRYPTED | pgp/gpg: keys via keyserver or my homepage | MAIL IS | www: http://www.doerges.net | WELCOME! |
