Ted Kremenek 146ef384da Fix subtle bug in AnalysisConsumer where we would not analyze functions whose parent
in the call graph had been inlined but for whatever reason we did not inline some
of its callees.

Also, fix a related traversal bug where we meant to do a BFS of the callgraph but
instead were doing a DFS.

Chandler Carruth 28969b4139 Remove a goofy CMake hack and use the standard CMake facilities to
express library-level dependencies within Clang.

This is no more verbose really, and plays nicer with the rest of the
CMake facilities. It should also have no change in functionality.

Anna Zaks 2774f99913 [analyzer] Cleanup for r157721.
We should lock the number of elements after the initial parsing is
complete. Recursive AST visitors in AnalyzesConsumer and CallGarph can
trigger lazy pch deserialization resulting in more calls to
HandleTopLevelDecl and appending to the LocalTUDecls list. We should
ignore those.

Ted Kremenek b2a470646a Change FunctionSummary.h's definition of SetOfDecls to be an ImmutableList instead
of a mutable SmallPtrSet.  While iterating over LocalTUDecls, there were cases
where we could modify LocalTUDecls, which could result in invalidating an iterator
and an analyzer crash.  Along the way, switch some uses of std::queue to std::dequeue,
which should be slightly more efficient.

Unfortunately, this is a difficult case to create a test case for.

Anna Zaks 8e0785286a [analyzer] PCH deserialization optimization.
We should not deserialize unused declarations from the PCH file. Achieve
this by storing the top level declarations during parsing
(HandleTopLevelDecl ASTConsumer callback) and analyzing/building a call
graph only for those.

Tested the patch on a sample ObjC file that uses PCH. With the patch, 
 the analyzes is 17.5% faster and clang consumes 40% less memory.
Got about 10% overall build/analyzes time decrease on a large Objective
C project.

A bit of CallGraph refactoring/cleanup as well..

Anna Zaks 54fd4a0766 [analyzer] Do not inline functions which previously reached max block
count.

This is an optimization for "retry without inlining" option. Here, if we
failed to inline a function due to reaching the basic block max count,
we are going to store this information and not try to inline it
again in the translation unit. This can be viewed as a function summary.

On sqlite, with this optimization, we are 30% faster then before and
cover 10% more basic blocks (partially because the number of times we
reach timeout is decreased by 20%).

Anna Zaks 5b3939fae6 [analyzer] Add an option to re-analyze a dead-end path without inlining.
The analyzer gives up path exploration under certain conditions. For
example, when the same basic block has been visited more than 4 times.
With inlining turned on, this could lead to decrease in code coverage.
Specifically, if we give up inside the inlined function, the rest of
parent's basic blocks will not get analyzed.

This commit introduces an option to enable re-run along the failed path,
in which we do not inline the last inlined call site. This is done by
enqueueing the node before the processing of the inlined call site
with a special policy encoded in the state. The policy tells us not to
inline the call site along the path.

This lead to ~10% increase in the number of paths analyzed. Even though
we expected a much greater coverage improvement. 

The option is turned off by default for now.

Anna Zaks 943c680605 [analyzer] Change the order in which we analyze the functions under
inlining to be the reverse of their declaration.

This optimizes running time under inlining up to 20% since we do not
re-analyze the utility functions which are usually defined first in the
translation unit if they have already been analyzed while inlined into
the root functions.

Anna Zaks ca70ed53da [analyzer] Use BFS over call graph when analysing functions.
BFS should give slightly better performance. Ex: Suppose, we have two
roots R1 and R2. A callee function C is reachable through both. However,
C is not inlined when analyzing R1 due to inline stack depth limit. With
DFS, C will be analyzed as top level even though it would be analyzed as
inlined through R2. On the other hand, BFS could avoid analyzing C as
top level.

Anna Zaks eee9110721 [analyzer] Use call graph to determine order in which functions are
analyzed.

The CallGraph is used when inlining is on, which is the current default.

This alone does not bring any performance improvement. It's a
stepping stone for the upcoming optimization in which we do not
re-analyze a function that has already been analyzed while inlined in
other functions. Using the call graph makes it easier to play with
the order of functions to minimize redundant analyzes.

Benjamin Kramer 7ec12c928a Revert my patches which removed Diagnostic.h includes by moving some operator overloads out of line.
This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

A patch by Dmitri Gribenko!

The attached patch fixes a use-after-free in AnalysisConsumer::HandleTranslationUnit.  The problem is that

order.

A crash happens only when reports have been added in AnalysisConsumer::HandleTranslationUnit's BugReporter. We don't have such checkers in clang so no test.

CMake complained about this while generating VS project files but was
okay with it while generating makefiles on Linux.

Argyrios Kyrtzidis 57d736fd46 [analyzer] Use the new registration mechanism for the debugging info "checks".
The relative checker package is 'debug':

'-dump-live-variables' is replaced by '-analyzer-checker=debug.DumpLiveVars'
'-cfg-view' is replaced by '-analyzer-checker=debug.ViewCFG'
'-cfg-dump' is replaced by '-analyzer-checker=debug.DumpCFG'

-Introduce CheckerV2, a set of templates for convenient declaration & registration of checkers.
 Currently useful just for checkers working on the AST not the path-sensitive ones.
-Enhance CheckerManager to actually collect the checkers and turn it into the entry point for
 running the checkers.
-Use the new mechanism for the LLVMConventionsChecker.

Argyrios Kyrtzidis 9d5235d527 When building StaticAnalyzer/Frontend add -I "<Checkers build dir>" to allow Checkers.inc to be
included without '..', thus being compatible with build systems of *BSDs.

Argyrios Kyrtzidis a6d04d541d [analyzer] Use the new registration mechanism on some of the internal checks. These are:
StackAddrLeakChecker
ObjCAtSyncChecker
UnixAPIChecker
MacOSXAPIChecker

The rest have/create implicit dependencies between checkers and need to be handled differently.

Argyrios Kyrtzidis 556c45e9c5 [analyzer] Overhauling of the checker registration mechanism.
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.

Argyrios Kyrtzidis 4ec3cf9937 [analyzer] Remove ManagerRegistry which is not used. In the future we may load analyzer plugins dynamically but
registration through static constructors should be avoided.
