[LLVMdev] Writing an LLVM Compiler Backend

[Misha Brukman]

Hi Rudskyy,

The place to ask LLVM-related questions is llvmdev at cs.uiuc.edu -- I've cc'd
the list.

Judging by your email, I assume you were looking at
http://llvm.org/docs/WritingAnLLVMBackend.html ?  If you're not familiar
with compilers or LLVM, consider reading some documents and looking at some
of the presentations here: http://llvm.org/docs/#llvmdesign .

You can also see how other backends are implemented in LLVM:
http://llvm.org/svn/llvm-project/llvm/trunk/lib/Target/ .  You'll want to
read about Tablegen: http://llvm.org/docs/TableGenFundamentals.html which
will tell you how to write the .td files to describe your target, and then
write the correct components (code generator, assembly printer, etc.) for
your target.

Good luck!

Misha
