llvm dev - Nov 2016 - Generation of IR for MyTarget

Hi Developers,

I have written C program and want to generate IR file for Specific Target I
have tried with following command but got a error as follows,
COMMAND:
*clang -S -emit-llvm -march=leg ~/llc-test-examples/ex9.c -o
~/llc-test-examples/ex9.ll*
ERROR:

*error: unknown target CPU 'leg'*
So any please help me what all other step should I do previously to get my
*leg* target in clang. So that i can use -march=leg option in this
command.

Thanks and Regards
Varun

There are several different pieces here.  Assuming that you have added 
your target triple to Triple.h/.cpp, and have the LLVM part working, you 
need to create TargetInfo, and the corresponding toolchain. Look in the 
clang repository in
   lib/Basic/Targets.cpp
   lib/Driver/Tools.cpp
   lib/Driver/ToolChains.cpp
To see how it's done for other targets.
