[cfe-dev] Re-targeting clang to a new architecture

[Ned Gill]

Hi all.

I'm contemplating re-targeting clang to a new architecture.  Initially I'd  
like to just port the front end as a static analysis tool to use alongside  
our existing GCC based toolchain, but ultimately I'd like to write a code  
generator too.  Unfortunately my architecture has a couple of wrinkles  
that sometimes make life hard for compilers:

CHAR_BIT is 16 (i.e. the minimum addressable unit of memory is 16 bits)
It's a Harvard architecture with 16 bit data pointers and 24 bit function  
pointers.

Does anyone have any thoughts on how difficult it would be to target clang  
to this sort of architecture - just as a front end (for now)?


Thanks,
Ned.

p.s. I'm reading the group through gmane.org, in case that makes a  
difference to anyone
