Jordan Rose 9db2d9adef [analyzer] Add new debug helper clang_analyzer_warnIfReached.
This will emit a warning if a call to clang_analyzer_warnIfReached is
executed, printing REACHABLE. This is a more explicit way to declare
expected reachability than using clang_analyzer_eval or triggering
a bug (divide-by-zero or null dereference), and unlike the former will
work the same in inlined functions and top-level functions. Like the
other debug helpers, it is part of the debug.ExprInspection checker.

Daniel Jasper ca9f73812c Add -fmodule-map-file option.
With this option, arbitrarily named module map files can be specified
to be loaded as required for headers in the respective (sub)directories.

This, together with the extern module declaration allows for specifying
module maps in a modular fashion without the need for files called
"module.map".

Among other things, this allows a directory to contain two modules that
are completely independent of one another.

Daniel Jasper ba7f2f7110 Module use declarations (II)
Review: http://llvm-reviews.chandlerc.com/D1546.

I have picked up this patch form Lawrence
(http://llvm-reviews.chandlerc.com/D1063) and did a few changes.

From the original change description (updated as appropriate):
This patch adds a check that ensures that modules only use modules they
have so declared. To this end, it adds a statement on intended module
use to the module.map grammar:

  use module-id

A module can then only use headers from other modules if it 'uses' them.
This enforcement is off by default, but may be turned on with the new
option -fmodules-decluse.

When enforcing the module semantics, we also need to consider a source
file part of a module. This is achieved with a compiler option

-fmodule-name=<module-id>.

The compiler at present only applies restrictions to the module directly
being built.

Hal Finkel c4d7c82c7f Add the intrinsic __builtin_convertvector
LLVM supports applying conversion instructions to vectors of the same number of
elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to
cause such instructions to be generated when using builtin vector types.

C-style casting on vectors is already defined in terms of bitcasts, and so
cannot be used for these conversions as well (without leading to a very
confusing set of semantics). As a result, this adds a __builtin_convertvector
intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is
intended to aid the creation of vector intrinsic headers that create generic IR
instead of target-dependent intrinsics (in other words, this is a generic
_mm_cvtepi32_ps). As noted in the documentation, the action of
__builtin_convertvector is defined in terms of the action of a C-style cast on
each vector element.

Ed Schouten 401aebab93 Make __has_extension(c_thread_local) work.
Unlike C++11's "thread_local" keyword, C11's "_Thread_local" is in the
reserved namespace, meaning we provide it unconditionally; it is marked
as KEYALL in TokenKinds.def.

This means that like all the other C11 keywords, we can expose its
presence through __has_extension().

Daniel Jasper 97292843d0 Support for modular module-map-files
This patch is the first step to make module-map-files modular (instead
of requiring a single "module.map"-file per include directory). This
step adds a new "extern module" declaration that enables
module-map-files to reference one another along with a very basic
implementation.

The next steps are:

* Combine this with the use-declaration (from
  http://llvm-reviews.chandlerc.com/D1546) in order to only load module
  map files required for a specific compilation.
* Add an additional flag to start with a specific module-map-file (instead
  of requiring there to be at least one "module.map").

Nico Rieck 7857d46c64 Add -fansi-escape-codes option
Some build systems use pipes for stdin/stderr. On nix-ish platforms colored
output can be forced by -fcolor-diagnostics. On Windows this option has
no effect in these cases because LLVM uses the console API (which only
operates on the console buffer) even if a console wrapper capable of
interpreting ANSI escape codes is used.

The -fansi-escape-codes option allows switching from the console API to
ANSI escape codes. It has no effect on other platforms.

Hans Wennborg 9f6581bb88 Allow _clang-format as alternative to .clang-format config filename
Dotfiles are impractical on Windows. This makes clang-format search
for the style configuration file as '_clang-format' in addition to
the usual '.clang-format'. This is similar to how VIM searches for
'_vimrc' on Windows.

Jordan Rose 2de3daa0a2 [analyzer] Enable destructor inlining by default (c++-inlining=destructors).
This turns on not only destructor inlining, but inlining of constructors
for types with non-trivial destructors. Per r178516, we will still not
inline the constructor or destructor of anything that looks like a
container unless the analyzer-config option 'c++-container-inlining' is
set to 'true'.

In addition to the more precise path-sensitive model, this allows us to
catch simple smart pointer issues:

  #include <memory>

  void test() {
    std::auto_ptr<int> releaser(new int[4]);
  } // memory allocated with 'new[]' should not be deleted with 'delete'

Rafael Espindola adea16bd9e Don't compute a patched/semantic storage class.
For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.

This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.

Jordan Rose d9759fdb03 Release notes: mention support for Unicode and UCNs in identifiers.
I'm using the name "Extended Identifiers" for the feature because that's
what GCC calls them. According to the standard, the new feature is
"universal character names are now allowed in identifiers", but the more
interesting "feature" is that identifiers can now contain Unicode characters,
however they are written.

Manuel Klimek bee085762b Implements equalsNode for Decl and Stmt.
This is a powerful tool when doing iterative refined matches,
where another match is started inside the match callback of the first
one; this allows for example to find out whether the node was in
the condition or body of its parent if-statement.

Manuel Klimek 4feac28e0e Cleanup of ASTMatcher macros and adding support for overloaded matchers.
This is in preparation for adding other overloaded matchers. This change
alone is a net win in LOC.
I went through all matchers and looked whether we could now encode them
as macro, or simplify them with the matcher atoms that were not
available before.

Manuel Klimek abf4371339 Implements the convenience matcher findAll.
We found that findAll has been implemented incorrectly multiple times
by various people using the matchers. To prevent further wasted
development effort, it makes sense to add it as convenience matcher
implemented as eachOf(m, forEachDescendant(m)).

This patch also updates the docs with the new matchers.

Chad Rosier ae229d599b [ubsan] Implement the -fcatch-undefined-behavior flag using a trapping
implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

Sean Silva cd61d28c4a analyzer: add initial Sphinx configuration
This is just the output of sphinx-quickstart. Now all that is needed
to begin converting the analyzer docs to reST is the server-side setup.

The analyzer folks have asked me to keep this segregated from the other
clang docs since the analyzer is a logically separate project (and has
its own separate web page) even though it resides in the clang tree.

Sean Silva b045514abf docs: Mark ReleaseNotes as "In-Progress"
Even though we do have a `.. warning::` directive on the page, hopefully
having "In-Progress" in the title will help to condition people's
expectations a bit for when they run into the extremely bare-bones
release notes.

Also, when release season comes around again, maybe this will get
people's attention and avoid confusion about what is going into the
upcoming release, and what is for changes to trunk for the next version.

llvm-svn: 171419
2013-01-02 22:05:33 +00:00
Sean Silva aaa78eefe7 docs: Take advantage of extra level of headings.
The way Sphinx treats the "top-level" adornments is weird. It usually
uses the first top-level adornment as the page title, even if the
top-level adornment is just one "section" out of many (i.e. if the first
section is "Introduction", then it will make the page title be
"Introduction"). This behavior can be overriden by using an explicit
`..  title::` directive to set the title.

Since the Sphinx stylesheet that Clang is currently using ('haiku')
nicely puts the document title at the top of the page in the header,
this weird default behavior was resulting in a redundant "title" in the
body content. Getting rid of this redundant level of headings
effectively "exposes" one more level of heading from the stylesheet to
which now makes the real "sections" more distinct.

section on the landing page nicely fit hierarchically under
LanguageExtensions.rst, so put them under LanguageExtensions.rst's
toctree instead of on the landing page.

Sean Silva dd9f40641c docs: Reorganize landing page.
I clustered the docs by some intuitive/fuzzy notion of "similarity", and
some reasonable categories seemed to materialize. I tried to give the
clusters useful names, but you may want to take a look at the landing
page (<http://clang.llvm.org/docs/> for the lazy) and share your
thoughts.

I have to say, this small change really gives the docs a whole new life!
It makes our documentation quite a bit easier to navigate and scope out.

Sean Silva fe25144e68 docs: Convert ReleaseNotes to reST.
This is the last of the "regular" documents to convert to reST, and so
I'm declaring the initial clang reST conversion "done".

However,

- There are some documents in clang/www/ which probably should
  be migrated into clang/docs/, such as www/OpenProjects.html

  The primary thing blocking me from doing this right now is not knowing
  how to set up a redirect so that the old URL's continue to work.

- LibASTMatchersReference.html is not reST. This page is auto-generated
  by clang/docs/tools/dump_ast_matchers.py from the source and has some
  collapse/expand logic that isn't expressible directly with Sphinx, so
  just converting it to reST is not really a good strategy.

  Manuel Klimek and I discussed this and the general agreed-upon
  direction is making that page data-driven so that it, say, pulls in an
  auto-generated blob of JSON which describes the matchers and builds up
  the "matcher reference" part of the page with a small amount of JS.

- There are some rogue .txt files hanging around.

Also, I dropped the little dragon logo at the top because Sphinx was
warning about an external image reference (not sure why, but meh, I
didn't want to fight it). If anything, we would want such a logo
integrated into the site's overall theme, rather than hardcoded here.

Andy Gibbs 0fea04509a Change VerifyDiagnosticConsumer so that it *must* contain at least one "expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive.
This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.

Jordan Rose 219c9d0dd3 [analyzer] Though C++ inlining is enabled, don't inline ctors and dtors.
More generally, this adds a new configuration option 'c++-inlining', which
controls which C++ member functions can be considered for inlining. This
uses the new -analyzer-config table, so the cc1 arguments will look like this:

... -analyzer-config c++-inlining=[none|methods|constructors|destructors]

Note that each mode implies that all the previous member function kinds
will be inlined as well; it doesn't make sense to inline destructors
without inlining constructors, for example.

The default mode is 'methods'.

Because the CXXNewExpr appears after the CXXConstructExpr in the CFG, we don't

whether or not to inline. The long-term fix (discussed in PR12014) might be to
introduce a new CFG node (CFGAllocator) that appears before the constructor.

Ted Kremenek 98b771ecc2 Review, comment, and reformat IPA.txt, including feedback comments.
Formatting includes:

- removing line wraps (Emacs Cmd-Q), to make text easier to read
- provide useful indentation
- call out caveats and notes more explictly

Stylistically, I prefer the document talk in 3rd person instead of "we".  The
term "we" is unambiguous, and sometimes refers to different things.  I've passed
over the existing paragraphs and made them speak more about specific entities
that compose the analyzer and what they do (e.g., ExprEngine) instead of "we"
referring to the analyzer.

Further, I have substituted some vague concepts such as "state" or "program
state" and replaced them with their precise implementation counterparts (e.g.,
ProgramState).  This makes the document more technically precise throughout the
entire narrative, which would sometimes use vague terms and other times precise
terms.

I've placed several comments within the document, which can be seen with
***TMK/COMMENT***, which indicate places that need to be enhanced or clarified,
or called out as questions about intended bheavior.

Jordan Rose e3e95cdf27 [analyzer] Set the default IPA mode to 'basic-inlining', which excludes C++.
Under -analyzer-ipa=basic-inlining, only C functions, blocks, and C++ static
member functions are inlined -- essentially, the calls that behave like simple
C function calls. This is essentially the behavior in Xcode 4.4.

C++ support still has some rough edges, and we don't want users to be worried
about them if they download and run their own checker. (In particular, the
massive number of false positives for analyzing LLVM comes from inlining
defensively-written code in contexts where more aggressive assumptions are
implicitly made. This problem is not unique to C++, but it is exacerbated by
the higher proportion of code that lives in header files in C++.)

The eventual goal is to be comfortable enough with C++ support (and simple
Objective-C support) to advance to -analyzer-ipa=inlining as the default
behavior. See the IPA design notes for more details.

John McCall d8561f058d Fix a pair of bugs relating to properties in ARC.
First, when synthesizing an explicitly strong/retain/copy property
of Class type, don't pretend during compatibility checking that the
property is actually assign.  Instead, resolve incompatibilities
by secretly changing the type of *implicitly* __unsafe_unretained
Class ivars to be strong.  This is moderately evil but better than
what we were doing.

Second, when synthesizing the setter for a strong property of
non-retainable type, be sure to use objc_setProperty.  This is
possible when the property is decorated with the NSObject
attribute.  This is an ugly, ugly corner of the language, and
we probably ought to deprecate it.

The first is rdar://problem/12039404;  the second was noticed by
inspection while fixing the first.

This code is very sensitive to the difference between "columns" as printed
and "bytes" (SourceManager columns). All variables are now named explicitly
and our assumptions are (hopefully) documented as both comment and assertion.

Whether parseable fixits should use byte offsets or Unicode character counts
is pending discussion on the mailing list; currently the implementation uses
bytes (and has no problems on lines containing multibyte characters).
This has been added to the user manual.

Chris Lattner 209ad6baa0 Jordan points out that this was incorrect: clang should recover from
*errors* with fixits on them by following the recovery advised by the
fixit, but if it is a fixit on a warning, then obviously the AST 
should be for the code as-written.

Jordan Rose f919803001 Downgrade the "direct comparison" error for ObjC literals to a warning.
Chris pointed out that while the comparison is certainly problematic
and does not have well-defined behavior, it isn't any worse than some
of the other abuses that we merely warn about and doesn't need to make
the compilation fail.

Revert the release notes change (r159766) now that this is just a new warning.

Jordan Rose 2783b6c0e5 Release notes for r158230 "Disallow using ObjC literals in direct comparisons"
This may turn out to be a controversial change, due to string literals being
uniqued at link time, but Apple's docs only say "The compiler makes such
object constants unique on a per-module basis..."[1] without actually saying
what a "module" is. (It's not a clang module.) Furthermore, this uniqueness
guarantee often can't be guaranteed once the string has been passed through
framework code.

If this does turn out very controversial, we could downgrade this to a
DefaultError warning for strings, and leave it as a true Error for other
kinds of literals.

Hans Wennborg d3b01bc7c6 Support the tls_model attribute (PR9788)
This adds support for the tls_model attribute. This allows the user to
choose a TLS model that is better than what LLVM would select by
default. For example, a variable might be declared as:

  __thread int x __attribute__((tls_model("initial-exec")));

if it will not be used in a shared library that is dlopen'ed.

This depends on LLVM r159077.

Richard Smith 1bb8edb8ac In response to some discussions on IRC, tweak the wording of the new
-Wsometimes-uninitialized diagnostics to make it clearer that the cause
of the issue may be a condition which must always evaluate to true or
false, rather than an uninitialized variable.

To emphasize this, add a new note with a fixit which removes the
impossible condition or replaces it with a constant.

Also, downgrade the diagnostic from -Wsometimes-uninitialized to
-Wconditional-uninitialized when it applies to a range-based for loop,
since the condition is not written explicitly in the code in that case.

std::is_trivially_constructible<T, Args...>, which can't be
implemented purely as a library.

Since __is_trivially_constructible can have zero or more arguments, I
needed to add Yet Another Type Trait Expression Class, this one
handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

David Blaikie 040a3a28f1 Remove the unuseful -fdiagnostics-show-name
This option was added in r129614 and doesn't have any use case that I'm aware
of. It's possible that external tools are using these names - and if that's
the case we can certainly reassess the functionality, but for now it lets us
shave out a few unneeded bits from clang.

Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool.
This removes the actual diagnostic name strings from clang entirely.
