For example, when renaming `a:🅱️❌:foo` to `y::foo` below, replacing
`x::foo()` with `y::foo()` can cause ambiguity. In such cases, we simply fully

namespace a {

Here’s a patch to add preinclude of stdc-predef.h.
The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;
The preinclude is inhibited with –ffreestanding.
Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.
I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here
Note: this is a recommit after a test failure took down the original (r318669)

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

This saves some cycles when compiling with "-w".
(Also fix a potential crash on invalid code for tools that tries to recover from some
errors, because analysis might compute the CFG which crashes if the code contains
invalid declaration. This does not happen normally with because we also don't perform
these analysis if there was an error.)

This commit changes the way that the refactoring operation classes are
structured:
- Users have to call `initiate` instead of constructing an instance of the
class. The `initiate` is now supposed to have custom initiation logic, and
you don't need to subclass the builtin requirements.
- A new `describe` function returns a structure with the id, title and the
description of the refactoring operation.
The refactoring action classes are now placed into one common place in
RefactoringActions.cpp instead of being separate.
Differential Revision: https://reviews.llvm.org/D38985
llvm-svn: 316780
Summary:
This defines a `clang::tooling::ToolExecutor` interface that can be extended to support different execution plans including standalone execution on a given set of TUs or parallel execution on all TUs in a codebase.
In order to enable multiprocessing execution, tool actions are expected to output result into a `ToolResults` interface provided by executors. The `ToolResults` interface abstracts how results are stored e.g. in-memory for standalone executions or on-disk for large-scale execution.
New executors can be registered as `ToolExecutorPlugin`s via the `ToolExecutorPluginRegistry`. CLI tools can use `createExecutorFromCommandLineArgs` to create a specific registered executor according to the command-line arguments.
This patch also implements `StandaloneToolExecutor` which has the same behavior as the current `ClangTool` interface, i.e. execute frontend actions on a given set of TUs. At this point, it's simply a wrapper around `ClangTool` at this point.
This is still experimental but expected to replace the existing `ClangTool` interface so that specific tools would not need to worry about execution.

There's a lot of misuse of Twine scattered around LLVM. This
ranges in severity from benign (returning a Twine from a function
by value that is just a string literal) to pretty sketchy (storing
a Twine by value in a class). While there are some uses for
copying Twines, most of the very compelling ones are confined
to the Twine class implementation itself, and other uses are
either dubious or easily worked around.
This patch makes Twine's copy constructor private, and fixes up
all callsites.
