As part of IBM's ongoing efforts to improve the AIX ecosystem, we are
working on adding support for the AIX platform to LLVM and Clang. Our goal
is to have a viable C and C++ LLVM compiler that runs and generates Power
code on AIX. The tentative plan is to initially support 32/64 bit mode in
AIX 7.1/7.2.

Our initial patches will focus on C support for AIX. In particular, we will
be focusing on:

  1. Adding initial XCOFF object file support.

  2. Emitting assembly compatible with the AIX system assembler.

We are also working on setting up AIX build bots and will update the list
when we have them ready to go.

Any feedback or comments are welcome.
