[fpc-devel] LLVM Backend?

[Samuel Crow]

Hello Michael,

The MIPS32 code for LLVM's code generator is out-of-date but salvageable.  If you're familiar with C++ I'd recommend anybody use LLVM for its massive optimizations, documentation and support classes.  If you want C/C++/Objective C compiler as well as other compilers working on your processor, LLVM would certainly be worth it.

If, on the other hand, you want only a Pascal compiler and don't care about the other languages, it is too soon to tell.  LLVM-FPC is still in its infancy.  I wish I could give you a more certain answer.  The best I can tell you is this:  If and when the softcores at Natami.net become available commercially, I will probably be making an LLVM backend for the 68050 rather than using the existing GCC backend for the 680x0 even though I program in C++.  Does that answer your question?
