When discussing the previous patch Alex said on underscores:

So it was intentionally.

r343949 - [coro]Pass rvalue reference for named local variable to return_value
Author: modocache
Date: Sun Oct 7 20:08:39 2018
New Revision: 343949
URL: http://llvm.org/viewvc/llvm-project?rev=343949=rev
Log:
[coro]Pass rvalue reference for named local variable to return_value
Summary:
Addressing https://bugs.llvm.org/show_bug.cgi?id=37265.
Implements [class.copy]/33 of coroutines TS.
When the criteria for elision of a copy/move operation are met, but not
for an exception-declaration, and the object to be copied is designated by an
lvalue, or when the expression in a return or co_return statement is a
(possibly parenthesized) id-expression that names an object with automatic
storage duration declared in the body or parameter-declaration-clause of the
innermost enclosing function or lambda-expression, overload resolution to select
the constructor for the copy or the return_value overload to call is first
performed as if the object were designated by an rvalue.

[PATCH] D52973: Add type_info predefined decl
mwasplund created this revision.
Herald added a subscriber: cfe-commits.
Bug 39052 - [Modules TS] MSVC std library produces ambiguous type_info
reference when including module with ms-compatibility
When compiling a modules-ts project with MSVC compatibility turned on the
type_info class was getting defined multiple times. With this change I am
adding the type_info class as a predefined decl to allow the reader/writer to
resolve the duplicated declarations.
On top of this I am adding an extra check to ignore redeclaration checks on
implicit types. This could be up for discussion since the spec does not specify
if the implicit types should be in the global unit or if they can be overridden
by the same type inside a module purview.

How `,` can be allowed if that is the suffix separator?
Also, i think `_` can be supported.

[PATCH] D51531: [analyzer][UninitializedObjectChecker] Uninit regions are only reported once
Szelethus added a comment. Another possibility could be to gather `CXXConstructorDecl`, and emit one warning per ctor, but it would be waaay to drastic.

[PATCH] D51866: [analyzer][UninitializedObjectChecker][WIP] New flag to ignore guarded uninitialized fields
Szelethus updated this revision to Diff 168592.
Szelethus added a comment.
Reimplemented with AST matchers.
@george.karpenkov I know you wanted to test this feature for a while, but sadly
I've been busy with the macro expansion related projects, I hope it's still
relevant.

[clang-tools-extra] r343937 - [clangd] NFC: Migrate to LLVM STLExtras API where possible
Author: omtcyfz
Date: Sun Oct 7 07:49:41 2018
New Revision: 343937
URL: http://llvm.org/viewvc/llvm-project?rev=343937=rev
Log:
[clangd] NFC: Migrate to LLVM STLExtras API where possible
This patch improves readability by migrating `std::function(ForwardIt
start, ForwardIt end, ...)` to LLVM's STLExtras range-based equivalent
`llvm::function(RangeT &, ...)`.
Similar change in Clang: D52576.

[PATCH] D52854: Use is.constant intrinsic for __builtin_constant_p
void added a comment. @rsmith I've been implementing your suggestion, but it's quickly becoming ridiculous. Just to implement a `ConstExpr` wrapper class, I need to touch ~23 files, virtually all changes being boilerplate code to forward the action to the wrapped expression. And this is before I add the code in this patch that implements the feature. While it would be nice to use LLVM's type system to determine if an expression is expected to be constant, it appears that doing that is much worse than adding the information to the bits field you mentioned.
