[include-fixer] Correct nested class search for identifiers with scoped information

Summary:
include-fixer will firstly try to use scoped namespace context information to
search identifier. However, in some cases, it's unsafe to do nested class
search, because it might treat the identifier as a nested class of scoped
namespace.

Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".

    namespace foo { Bar t; }

Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

only intended to work with a specific module.  The `updateModule` setter

There are fields in the `Verifier` class like `DeoptimizeDeclarations`
and `GlobalValueVisited` which are module specific, so a given
Verifier instance will not in fact work across multiple modules today.
This change just makes that more obvious.

The motivation is to make it easy to get to the datalayout of the
module unambiguously.  That is required to verify that `inttoptr` and
`ptrtoint` constant expressions are well typed in the face of
non-integral pointer types.

Sumanth Gundapaneni [Mon, 1 Aug 2016 21:28:03 +0000 (21:28 +0000)]
Build llvm with ccache if package is present

This patch has the following changes

The CMake variable LLVM_CCACHE_BUILD is set to OFF by default.
Set this to ON for a ccache enabled build

CCACHE_CPP2 is required to compile the source file directly instead
of compiling the preprocessed file. This will help WERROR is turned ON
for a host clang compiler

The below two options makes more sense in the context of a buildbot

CCACHE_HASHDIR is required to maintain the separate cached data across
builders. This will also help the debuggers to point to the correct source
location

CCACHE_SIZE is important in the perspective of buildbot to increase the
limit on the amount of data to hold in cache for faster compilation

CCACHE_DIR is used to save the cached data to a specific directory.

[msf] Teach LLVM to parse a split Fpm.

The FPM is split at regular intervals across the MSF file, as the MS code
suggests. It turns out that the value of the interval is precisely the
block size. If the block size is 4096, then there are two Fpm pages every
4096 blocks.

So here we teach the PDBFile class to parse a split FPM, and also add more
options when dumping the FPM to display some additional information such
as orphaned pages (pages which the FPM says are allocated, but which
nothing appears to use), use after free pages (pages which the FPM says
are not allocated, but which are referenced by a stream), and multiple use
pages (pages which the FPM says are allocated but are used more than
once).

[ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.

This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class
that is capable of lazy materialization (i.e. the symbol definition needn't be
emitted until the address is requested). This can be used to support common

For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver.

For space efficiency a new class, JITEvaluatedSymbol, is introduced that
behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an
address and symbol flags. Instances of JITEvaluatedSymbol can be used in

libc++: test lock-free atomic alignment

Summary:
libc++ implements std::atomic<_Tp> using __atomic_base<_Tp> with
`mutable _Atomic(_Tp) __a_`. That member must be suitably aligned on
relevant ISAs for instructions such as cmpxchg to work properly, but
this alignment isn't checked anywhere. __atomic_base's implementation
relies on _Atomic doing "the right thing" since it's under the
compiler's control, and only the compiler knows about lock-freedom and
instruction generation. This test makes sure that the compiler isn't
breaking libc++'s expectations.

I'm looking at a few odd things in the C++ standard, and will have a few
other fixes around this area in the future.

This requires building with `-DLIBCXX_HAS_ATOMIC_LIB=True`, the test
marks the dependency as REQUIRES and won't be run without.

[CFLAA] Remove modref queries from CFLAA.

As it turns out, modref queries are broken with CFLAA. Specifically,
the data source we were using for determining modref behaviors
explicitly ignores operations on non-pointer values. So, it wouldn't
note e.g. storing an i32 to an i32* (or loading an i64 from an i64*).
It also ignores external function calls, rather than acting
conservatively for them.

(N.B. These operations, where necessary, *are* tracked by CFLAA; we just
use a different mechanism to do so. Said mechanism is relatively
imprecise, so it's unlikely that we can provide reasonably good modref

7 years agoMake RecursiveASTVisitor visit lambda capture initialization expressions
Martin Bohme [Mon, 1 Aug 2016 12:15:46 +0000 (12:15 +0000)]
Make RecursiveASTVisitor visit lambda capture initialization expressions

Summary:
Lambda capture initializations are part of the explicit source code and
therefore should be visited by default but, so far, RecursiveASTVisitor does not
visit them.

This appears to be an oversight. Because the lambda body needs custom handling
(calling TraverseLambdaBody()), the DEF_TRAVERSE_STMT for LambdaExpr sets
ShouldVisitChildren to false but then neglects to visit the lambda capture
initializations. This patch adds code to visit the expressions associated with
lambda capture initializations.

[clang-tidy] Prepare modernize-loop-convert for upcoming changes in D22566

Summary:
D22566 will change RecursiveASTVisitor so that it descends into the initialization expressions for lambda captures.

modernize-loop-convert needs to be prepared for this so that it does not interpret these initialization expressions as invalid uses of the loop variable. The change has no ill effects without D22566 in place, i.e. the change does not depend on D22566.

Implement tooling::Replacements as a class.

Summary:
- Implement clang::tooling::Replacements as a class to provide interfaces to
  control how replacements for a single file are combined and provide guarantee
  on the order of replacements being applied.
- tooling::Replacements only contains replacements for the same file now.
  Use std::map<std::string, tooling::Replacements> to represent multi-file
  replacements.
- Error handling for the interface change will be improved in followup patches.
