[LLVMdev] LLVM-gcc for Ada

[Roger Mc Murtrie]

Hi Duncan,
   Thanks for your advice.
I'll see how I go with dragonegg.
I have been using gps for my Ada development but thought I should try and use XCode which is how I came across llvm.
Getting llvm working was more out of interest and challenge.
Regards
Roger
