Subject: [PATCH] [Clang] Add codegen option to add passbuilder callback
wsmoses wrote:
Let me fork off the clang part off into a separate PR from the codegenoption.
For context, I'm in an environment where I can't modify the LLVM build files
(but I can import them), but want to produce the modified clang, without
maintaining a separate fork just to add the pass.

The new option in CodeGenOptions.h seems fine.
If your goal is to statically inject passes into the clang executable, I don't
understand why the existing LLVM plugin infrastructure isn't sufficient for
your needs. You mention "modifying Extension.def", but that file is

@jdoerfert added the example test
@efriedma-quic I've reworked the mechanism to not create a global variable
within LLVM. Here this only applies to clang and enables two things:
1) Users of clang as a library can add a custom passbuilder callback by adding
to codegenoptions
2)

I don't think a global variable is the right interface for this; we've been
trying to move away from global variables because they cause breakage when LLVM
is used in multiple contexts in the same process.

Can you make an example on how this is used now? Is there a way to test this?

Adding passbuilder callbacks presently can be done one of two ways:
* a shared library plugin
* modifying the extensions list (and thus extensions.def)
