This check flags function top-level const-qualified return types and suggests removing the mostly-superfluous const qualifier where possible.
Patch by Yitzhak Mandelbaum.
llvm-svn: 345764
Summary:
This patch introduces a new clang-tidy check that matches on all `declStmt` that declare more then one variable
and transform them into one statement per declaration if possible.
It currently only focusses on variable declarations but should be extended to cover more kinds of declarations in the future.
It is related to https://reviews.llvm.org/D27621 and does use it's extensive test-suite. Thank you to firolino for his work!

We haven't supported compiling ObjC1 for a long time (and never will again), so
there isn't any reason to keep these separate. This patch replaces
LangOpts::ObjC1 and LangOpts::ObjC2 with LangOpts::ObjC.

Summary:
The macro may not have location (or more generally, the location may not exist),
e.g. if it originates from compiler's command-line.
The check complains on all the macros, even those without the location info.
Which means, it only says it does not like it. What is 'it'? I have no idea.
If we don't print the name, then there is no way to deal with that situation.
And in general, not printing name here forces the user to try to understand,
given, the macro definition location, what is the macro name?
This isn't fun.
Also, ignores-by-default the macros originating from command-line,
with an option to not ignore those.
I suspect some more issues may crop up later.

Make the following changes to PredefinedExpr:
1. Move PredefinedExpr below StringLiteral so that it can use its definition.
2. Rename IdentType to IdentKind to be more in line with clang's conventions,
and propagate the change to its users.
3. Move the location and the IdentKind into the newly available space of
the bit-fields of Stmt.
4. Only store the function name when needed. When parsing all of Boost,
of the 1357 PredefinedExpr 919 have no function name.

Detects when the integral literal or floating point (decimal or hexadecimal)
literal has non-uppercase suffix, and suggests to make the suffix uppercase,
with fix-it.
All valid combinations of suffixes are supported.
```
auto x = 1; // OK, no suffix.
auto x = 1u; // warning: integer literal suffix 'u' is not upper-case
auto x = 1U; // OK, suffix is uppercase.
...
```
This is a re-commit, the original was reverted by me in
rL345305 due to discovered bugs. (implicit code, template instantiation)
Tests were added, and the bugs were fixed.
I'm unable to find any further bugs, hopefully there aren't any..

- align struct names/comments with LSP, remove redundant "clangd" prefixes.
- don't map config structs as Optional<> when their presence/absence
doesn't signal anything and all fields must have sensible "absent" values
- be more lax around parsing of 'any'-typed messages

It doesn't make much sense: setting them is not coupled to opening the file,

For example:

absl::Duration d = absl::Seconds(10.0);
// Suggested - Use an integer instead.
absl::Duration d = absl::Seconds(10);

In production builds, it will send an error reply if none was sent,

Summary: This is useful when using clangd with CMake based projects in Visual Studio Code since when using CMake the `compile_commands.json` file is usually located in a `build` subdirectory which isn't a parent directory of the source files. Allowing passing relative paths to -compile-commands-dir allows specifying `clangd.arguments = ["-compile-commands-dir=build"]` in VSCode's settings file and having it work for each CMake based project that uses the `build` subdirectory as the build directory (instead of having to specify the absolute path to the compile commands directory for each separate project in VSCode's settings).

Summary:
See http://lists.llvm.org/pipermail/clangd-dev/2018-October/000171.html for context.
I kept the error (instead of downgrading to a log message) since the range lengths differing does indicate either a bug in the client or server range calculation or the buffers being out of sync (which both seems serious enough to me to be an error). If any existing clients aside from VSCode break they should only break when accidentally typing a Unicode character which should only be a minor nuisance for a little while until the bug is fixed in the respective client.
