<div dir="ltr">I have one more question regarding ARM codegen support. Is it possible to pass a flag to Codegen to generate only ARMv5 instructions and not to use instructions from higher versions, ( In other words, is this version specific information present in LLVM codegen?)<br>

</div>These would be best supported by adding builtins to llvm-gcc and<br>
adding intrinsics to llvm. Some of them could be implemented as <2 x<br>
i16> operations as well.<br>
<br>
Any help to implement this support would be great,<br>
