9 years ago[PM] Port SROA to the new pass manager.
Chandler Carruth [Sat, 12 Sep 2015 09:09:14 +0000 (09:09 +0000)]
[PM] Port SROA to the new pass manager.

In some ways this is a very boring port to the new pass manager as there
are no interesting analyses or dependencies or other oddities.

However, this does introduce the first good example of a transformation
pass with non-trivial state porting to the new pass manager. I've tried
to carve out patterns here to replicate elsewhere, and would appreciate
comments on whether folks like these patterns:

- A common need in the new pass manager is to effectively lift the pass
  class and some of its state into a public header file. Prior to this,
  LLVM used anonymous namespaces to provide "module private" types and
  utilities, but that doesn't scale to cases where a public header file
  is needed and the new pass manager will exacerbate that. The pattern
  I've adopted here is to use the namespace-cased-name of the core pass
  (what would be a module if we had them) as a module-private namespace.
  Then utility and other code can be declared and defined in this
  namespace. At some point in the future, we could even have
  (conditionally compiled) code that used modules features when
  available to do the same basic thing.

- I've split the actual pass run method in two in order to expose
  a private method usable by the old pass manager to wrap the new class
  with a minimum of duplicated code. I actually looked at a bunch of
  ways to automate or generate these, but they are all quite terrible
  IMO. The fundamental need is to extract the set of analyses which need
  to cross this interface boundary, and that will end up being too
  unpredictable to effectively encapsulate IMO. This is also
  a relatively small amount of boiler plate that will live a relatively
  short time, so I'm not too worried about the fact that it is boiler
  plate.

The rest of the patch is totally boring but results in a massive diff
(sorry). It just moves code around and removes or adds qualifiers to
reflect the new name and nesting structure.

Always_inline codegen rewrite.

Current implementation may end up emitting an undefined reference for

"available_externally alwaysinline" IR function for it and then failing to
inline all the calls. This happens when a call to such function is in dead
code. As the inliner is an SCC pass, it does not process dead code.

Libc++ relies on the compiler never emitting such undefined reference.

With this patch, we emit a pair of

2b. A declaration of F.

[analyzer] Add -analyzer-config option for function size the inliner considers as large

Add an option (-analyzer-config min-blocks-for-inline-large=14) to control the function
size the inliner considers as large, in relation to "max-times-inline-large". The option
defaults to the original hard coded behaviour, which I believe should be adjustable with
the other inlining settings.

The analyzer-config test has been modified so that the analyzer will reach the
getMinBlocksForInlineLarge() method and store the result in the ConfigTable, to ensure it
is dumped by the debug checker.
