I'm not sure about Windows DLLs, but shared libraries under Unix
require compiling the code position-independant, which involves
allocating a register to point to the look-up tables. GHC makes
pretty heavy use of registers, and the x86 is already short. The
chances are that doing this right now would impose a significant
performance hit.
The solution is to redesign GHC so that it uses less registers
(eg. having one stack instead of two), thus freeing up a register for
PIC code. So, we just need someone with the time and inclination to
implement it...
Cheers,
Simon
