New description:
dynamic library status:
{{{
* Supported: Linux 64bit, Mac OSX 64bit
* Unsupported: Linux 32bit, Mac OSX 32bit, Windows 32bit
}}}
The LLVM backend doesn't support dynamic libraries at the moment.
LLC supports a flag called '-relocation-mode' that can be used to support
this, it takes the following options:
{{{
default - let the target choose.
static - static code.
pic - PIC code.
dynamic-no-pic - Dynamic references but static code
}}}
This roughly corresponds to GHC -fPIC, and -dynamic flags.
Linux: Simply adding the correct flag to LLC seems to work fine.
Mac OSX, Windows: Adding the correct flag doesn't work at all, all
programs segfault.
