Patch to ./include/llvm/Support/ELF.h with the latest registered ELF e_machine names and values

[jwolfe]

Summary

CSR has just registered an ELF e-machine designation for their Kalimba srchitecture. Matthew Gardner has been doing a port of lldb for that family of chips and is awaiting the availability if EM_CSR_KALIMBA in the LLVM e-Machine enumerations.

As a maintainer of the Generic ABI registration, I am taking this opportunity to provide a current and complete list of registered e-machine values.

Is there a link to the "Generic ABI registration" that we can include in a comment?

[jwolfe]

The gABI document is available at:

http://www.uxsglobal.com/developers/gabi/

which covers the evolution of the Generic ABI. The current working
document is at:

http://www.uxsglobal.com/developers/gabi/latest/contents.html

with the current e-machine definitions in:

http://www.uxsglobal.com/developers/gabi/latest/ch4.eheader.html

Requests for new e-machine number registration/assignment are handled by
e-mail to the following equivalent e-mail addresses:

[e-mail]

[e-mail]

Discussions of feature/change requests to the Generic SysV ABI are
raised and discussed on the Generic System V Application Binary
Interface group on Google:

https://groups.google.com/forum/?fromgroups#!forum/generic-abi

Architecture and OS specific ABI sections are maintained by others.

At Rafael's suggestion, I have added a comment with the URL to the active generic System V ELF ABI registered machine architectures

This LGTM. Do you have commit access.

[jwolfe]

I do not currently have commit access. I and Matthew Gardner of CSR
would appreciate this being done.

I have been working with Ed Maste on LLDB for FreeBSD. He suggested
that I apply for commit access in the past, but
I have not moved forward with that request.

Thanks for your review, comments and assistance.
