I'm compiling the files for package javavm with GHC 6.6 (using
-package-name javavm). As part of the compilation process, I need a
runnable program that uses the modules I've compiled in place:
import JVMBoot
But I get this error when compiling my Main module (ShowClasses.hs):
The main program must be in package 'main', which is why compiling ShowClasses
with -package-name javavm doesn't work. I'll modify the documentation to say
this more clearly
When you say import JVMBoot, and your javavm package is not installed, GHC
thinks you mean JVMBoot from package main.

I can't install it, the package isn't finished being built at that
point. Or perhaps I could find a way of installing the partial package
to the user database.
I build part of package javavm. Then I use that to build
Hmm. Ghc doesn't really give you a way to *run* a package which is so
partly-built that you can't install it. That's perhaps not clever, but I think
it's the current story.

That sounds plausible

Hello,
I'm trying to get GHC to run on the Cell processor. That is, just on the
PPU PowerPC side. The SPUs will continue to run C programs, managed and
driven by a Haskell manager on the PPU. I'm mostly interested in GHC for
its concurrency features (STM in particular).
Not knowing much about

ghc 6.6 added 'inline' function, see user docs. although only SPJ knows
whether it can be used here:
compose f g = inline (\x - f (g x))

While they are supported in theory, I couldn't get LLVM to generate
any tailcalls. Maybe I've done something wrong, maybe they're not
really implemented yet.
it seems that ghc could benefit from a tail-call
