clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.
Renamed -check-objc-methodsigs to -warn-objc-methodsigs.
The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc
llvm-svn: 53575
ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".
The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.
Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.
Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).

'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions
using the default(?) names like "i686-pc-linux-gnu".'

when it is constructed via deserialization. This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object. This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.
The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc. During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.
llvm-svn: 50149
clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and
passes it to the preprocessor object.
clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main().
html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new
Preprocessor to highlight macros.
class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros().
Updated clients of HTMLDiagnostics to use this new interface.
llvm-svn: 49875
currently doesn't pass in the Preprocessor from the driver, so we don't get
syntax highlighting when we create HTMLDiagnostics in that way.
llvm-svn: 49796
problems, including the fact that it doesn't work well with multi-line
comments due to Ted's crazy table. However, that could be fixed, and it
does work with single-line ones :).
llvm-svn: 49778
GRSimpleVals.h
Added a PathDiagnosticClient option to the driver functions for the
CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o"
argument from the driver that specifies where HTML reports should be dumped.
llvm-svn: 48989
that are not related to error nodes.
Fixed bug where we did not detect some NULL dereferences.
Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach
a set of provided nodes.
Fixed subtle bug in ExplodedNodeImpl where we could create predecessor
iterators that included the mangled "sink" bit. The better fix is to integrate
this bit into the void* for the wrapped State, not the NodeGroups representing
a node's predecessors and successors.
llvm-svn: 48036
theoretically useful, but not useful in practice. It adds a bunch of
complexity, and not much value. It's best to nuke it. One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay). Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.
Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed. Please poke at it when you have
time.
llvm-svn: 47930
the system headers dir. This produces an annoying warning:
clang.cpp:883: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object
I'm not sure how to remove it. :(
llvm-svn: 47836
probably make this a separate command line option later.
Added "--analyze-function" option to the driver to (gradually) allow different
analyses to only be run on specific functions. Currently only --grsimple uses
this option.
llvm-svn: 47285
--grsimple except that it visualizes the ExplodedGraph using dot and
outputs the current function being analyzed. --grsimple is now silent
except when it emits diagnostics.
llvm-svn: 47146
level code in clang. This is a cleanup, but does implement "-o" for
-emit-llvm. One effect of this is that "clang foo.c -emit-llvm" will now
emit into foo.ll instead of stdout. Use "clang foo.c -emit-llvm -o -" or
"clang < foo.c -emit-llvm" to get the old behavior.
llvm-svn: 46791
both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.
llvm-svn: 45228
Added "SourceFile" string to TranslationUnit to record corresponding
source file.
Updated serialization of TranslationUnits and logic in the driver to
correctly pass the source file information to the serializer.
llvm-svn: 45211
warnings. This flag is the inverse of to GCC's -Wformat-nonliteral option (in
the clang driver, these warnings are on by default).
Patch provided by Shantonu Sen.
llvm-svn: 45103
the internal representation. This also fixes a bug where -I foo -F foo would
not search foo as both a normal and framework include dir.
llvm-svn: 45092
create a .ast file in the current working directory. This mirrors the behavior
of the -c option for gcc. Later we should add the ability to write the
serialized file anywhere.
llvm-svn: 45004
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:
FullLoc.getManager().someMethod(FullLoc.getLocation());
instead we have:
FullLoc.someMethod();
Modified TextDiagnostics (and related classes) to use this short-hand.
llvm-svn: 44957
and into the "Basic" library. TargetInfo objects are now
constructed from triples by calling the static method
TargetInfo::CreateTargetInfo.
llvm-svn: 44940
SourceManager*'s instead of SourceManager&'s. This allows the client specify a
NULL SourceManager when using a default constructed SourceLocation. Thus the
SourceManager can be NULL when the SourceLocation's isValid() == false.
The interface to most clients of Diagnostic remains the same.
Diagnostic::Report() is overload to either accept a SourceLocation and a
SourceManager&, or neither. Thus clients that do not have a SourceManager
cannot specify a SourceLocation.
Modified TextDiagnostics* to use this new interface.
Modified the driver to not passed in SourceManager when warning about "-I-".
llvm-svn: 44887
SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.
Modified all users of Diagnostics to comply with this new interface.
Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).
Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.
llvm-svn: 44878
GetLanguage, and InitializeLangOptions. The goal is to break up this logic
into atomic units of functionality that can later be refactored into better
driver logic that is capable of handling a mixture of source files of
different languages.
llvm-svn: 44642
deserialized ASTs into the function CreateASTConsumer(). This function
is called by ProcessInputFile, and soon the logic that processes deserialized
ASTs.
llvm-svn: 44618
we default to "i386-apple-darwin". This is an interim solution.
Removed processing of "linux" triples from Targets.cpp, since we don't have
any sensical Linux target support (yet).
Cleaned up error processing of targets; added better diagnostics.
llvm-svn: 44560
replaces the functionality previously provided by just "-arch" (which is still
supported but has different semantics).
The new behavior is as follows:
(1) If the user does not specify -triple:
(a) If no -arch options are specified, the target triple used is the host
triple (in llvm/Config/config.h).
(b) If one or more -arch's are specified (and no -triple), then there is
one triple for each -arch, where the specified arch is substituted
for the arch in the host triple. Example:
host triple = i686-apple-darwin9
command: clang -arch ppc -arch ppc64 ...
triples used: ppc-apple-darwin9 ppc64-apple-darwin9
(2) The user does specify a -triple (only one allowed):
(a) If no -arch options are specified, the triple specified by -triple
is used. E.g clang -triple i686-apple-darwin9
(b) If one or more -arch options are specified, then the triple specified
by -triple is used as the primary target, and the arch's specified
by -arch are used to create secondary targets. For example:
clang -triple i686-apple-darwin9 -arch ppc -arch ppc64
has the following targets:
i686-apple-darwin9 (primary target)
ppc-apple-darwin9
ppc64-apple-darwin9
Other changes related to the changes to the driver:
- TargetInfoImpl now includes the triple string.
- TargetInfo::getTargetTriple returns the triple for its primary target.
- test case test/Parser/portability.c has been updated because "-arch linux" is
no longer valid ("linux" is an OS, not an arch); instead we use a bogus
architecture "bogusW16W16" where WCharWidth=16 and WCharAlign=16.
llvm-svn: 44551
serialization logic as well as driver code is now in
Driver/SerializationTest.cpp. The status of this code is that it
should be used by no clients.
Added --test-pickling option to driver to run the serialization code.
Modified IdentifierInfo and IdentifierTable to have friend classes
that permit object serialization. Such friendship may not be needed
in the final design.
