J. Ryan Stinnett c07bc2962c [Attr] Add noipa function attribute (#203304)
This adds a `noipa` function attribute to LLVM IR. This new attribute
disables any interprocedural analysis that inspects the definition of
the function. Setting this attribute is equivalent to moving the
function definition to a separate, optimizer-opaque, module.

The `noipa` attribute does *not* control inlining or outlining. Add the
`noinline` and `nooutline` attributes as well in cases where inlining
and outlining should additionally be disabled.

-*- llvm/utils/vim/README -*-

This directory contains settings for the vim editor to work on llvm *.ll and
tablegen *.td files. It comes with filetype detection rules in the (ftdetect),
syntax highlighting (syntax), some minimal sensible default settings (ftplugin)
and indentation plugins (indent).

To install copy all subdirectories to your $HOME/.vim or if you prefer create
symlinks to the files here. Do not copy the vimrc file here it is only meant as
an inspiration and starting point for those working on llvm c++ code.

Note: If you notice missing or incorrect syntax highlighting, please contact
<llvm-bugs [at] lists.llvm.org>; if you wish to provide a patch to improve the
functionality, it will be most appreciated. Thank you.

If you find yourself working with LLVM Makefiles often, but you don't get syntax
highlighting (because the files have names such as Makefile.rules or
TEST.nightly.Makefile), add the following to your ~/.vimrc:

  " LLVM Makefile highlighting mode
  augroup filetype
    au! BufRead,BufNewFile *Makefile*     set filetype=make
  augroup END
