NAKAMURA Takumi 7f633dfe99 [CMake] Move CLANG_ENABLE_(ARCMT|OBJC_REWRITER|STATIC_ANALYZER) into clang/Config/config.h.
LLVM_ENABLE_MODULES is sensitive of -D. Move them into config.h.

FIXME: It'd be better that they are #cmakedefine01 rather than #cmakedefine.
(#if FOO rather than #if defined(FOO))
Then we can find missing #include "clang/Config/config.h" in the future.

Sylvestre Ledru b78f3b89e1 Also add the option -no-pie (like -nopie)
Summary:
For example, this option is expected by ghc (haskell compiler). Currently, building with ghc will fail with:

```
clang: error: unknown argument: '-no-pie'
`gcc' failed in phase `Linker'. (Exit code: 1)
. /usr/share/haskell-devscripts/Dh_Haskell.sh && \
configure_recipe
```

This won't do anything (but won't fail with an error)

Faisal Vali ac506d7494 [NFC] Refactor the Preprocessor function that handles Macro definitions and rename Arguments to Parameters in Macro Definitions.
- Extracted the reading of the tokens out into a separate function.
  - Replace 'Argument' with 'Parameter' when referring to the identifiers of the macro definition (as opposed to the supplied arguments - MacroArgs - during the macro invocation).

This is in preparation for submitting patches for review to implement __VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective function and making it less comprehensible.

I will also directly update some extra clang tooling that is broken by the change from Argument to Parameter.

Hopefully the bots will stay appeased.

Olivier Goffart 90f981bc5b Keep the IdentifierInfo in the Token for alternative operator keyword
The goal of this commit is to fix clang-format so it does not merge tokens when
using the alternative spelling keywords. (eg: "not foo" should not become "notfoo")

The problem is that Preprocessor::HandleIdentifier used to drop the identifier info
from the token for these keyword. This means the first condition of
TokenAnnotator::spaceRequiredBefore is not met. We could add explicit check for
the spelling in that condition, but I think it is better to keep the IdentifierInfo
and handle the operator keyword explicitly when needed. That actually leads to simpler
code, and probably slightly more efficient as well.

Another side effect of this change is that __identifier(and) will now work as
one would expect, removing a FIXME from the MicrosoftExtensions.cpp test

Alex Lorenz 50b2dd336e [ObjC] Pick a 'readwrite' property when synthesizing ambiguous
property and check for incompatible attributes

This commit changes the way ambiguous property synthesis (i.e. when synthesizing
a property that's declared in multiple protocols) is performed. Previously,
Clang synthesized the first property that was found. This lead to problems when
the property was synthesized in a class that conformed to two protocols that
declared that property and a second protocols had a 'readwrite' declaration -
the setter was not synthesized so the class didn't really conform to the second
protocol and user's code would crash at runtime when they would try to set the
property.

This commit ensures that a first readwrite property is selected. This is a
semantic change that changes users code in this manner:

```
@protocol P @property(readonly) int p; @end
@protocol P2 @property(readwrite) id p; @end
@interface I <P2> @end
@implementation I
@syntesize p; // Users previously got a warning here, and Clang synthesized
              // readonly 'int p' here. Now Clang synthesizes readwrite 'id' p..
@end
```

To ensure that this change is safe, the warning about incompatible types is
promoted to an error when this kind of readonly/readwrite ambiguity is detected
in the @implementation. This will ensure that previous code that had this subtle
bug and ignored the warning now will fail to compile with an error, and users
should not get suprises at runtime once they resolve the error.

The commit also extends the ambiguity checker, and now it can detect conflicts
among the different property attributes. An error diagnostic is used for
conflicting attributes, to ensure that the user won't get "suprises" at runtime.

ProtocolPropertyMap is removed in favour of a a set + vector because the map's
order of iteration is non-deterministic, so it couldn't be used to select the
readwrite property.

Matthias Gehre 351c218d15 CFG: Add CFGElement for automatic variables that leave the scope
Summary:
This mimics the implementation for the implicit destructors. The
generation of this scope leaving elements is hidden behind
a flag to the CFGBuilder, thus it should not affect existing code.

Currently, I'm missing a test (it's implicitly tested by the clang-tidy
lifetime checker that I'm proposing).
I though about a test using debug.DumpCFG, but then I would
have to add an option to StaticAnalyzer/Core/AnalyzerOptions
to enable the scope leaving CFGElement,
which would only be useful to that particular test.

Any other ideas how I could make a test for this feature?

getTypeSize and with getIntWidth are not equivalent for bool

this causes a number of issues
(for instance, if APint X representing a bool is created

(because of the different bit width), that results in crashes

Sterling Augustine 1cda1d76b1 Allow CompilerInvocations to generate .d files.
Summary:
Most clang tools should ignore the -M
family of options because one wouldn't want them
to generate a new dependency (.d) file. However,
some tools may want this dependency file. This
patch creates a mechanism for them to do this.

This implementation just plumbs a boolean down
several layers of calls. Each of the modified calls
has several call sites, and so a single member
variable or new API entry point won't work.

An alternative would be to write a function to filter
the -M family of arguments out of CC1Args, and have
each caller call that function by hand before calling
newInvocation, Invocation::run, or buildAstFromCodeWithArgs.
This is a more complicated and error-prone solution.
Why burden all the callers to remember to use
this function?

But I could rewrite this patch to use that method if
that is deemed more appropriate.
