Ted Kremenek [Wed, 27 Aug 2014 15:14:15 +0000 (15:14 +0000)]
Add support for the static analyzer to synthesize function implementations from external model files.

Currently the analyzer lazily models some functions using 'BodyFarm',
which constructs a fake function implementation that the analyzer
can simulate that approximates the semantics of the function when
it is called.  BodyFarm does this by constructing the AST for
such definitions on-the-fly.  One strength of BodyFarm
is that all symbols and types referenced by synthesized function
bodies are contextual adapted to the containing translation unit.
The downside is that these ASTs are hardcoded in Clang's own
source code.

A more scalable model is to allow these models to be defined as source
code in separate "model" files and have the analyzer use those
definitions lazily when a function body is needed.  Among other things,
it will allow more customization of the analyzer for specific APIs
and platforms.

This patch provides the initial infrastructure for this feature.
It extends BodyFarm to use an abstract API 'CodeInjector' that can be
used to synthesize function bodies.  That 'CodeInjector' is
implemented using a new 'ModelInjector' in libFrontend, which lazily
parses a model file and injects the ASTs into the current translation
unit.

Models are currently found by specifying a 'model-path' as an
analyzer option; if no path is specified the CodeInjector is not
used, thus defaulting to the current behavior in the analyzer.

Models currently contain a single function definition, and can
be found by finding the file <function name>.model.  This is an
initial starting point for something more rich, but it bootstraps
this feature for future evolution.

This patch was contributed by Gábor Horváth as part of his
Google Summer of Code project.

Some notes:

- This introduces the notion of a "model file" into
  FrontendAction and the Preprocessor.  This nomenclature
  is specific to the static analyzer, but possibly could be
  generalized.  Essentially these are sources pulled in
  exogenously from the principal translation.

  Preprocessor gets a 'InitializeForModelFile' and
  'FinalizeForModelFile' which could possibly be hoisted out
  of Preprocessor if Preprocessor exposed a new API to
  change the PragmaHandlers and some other internal pieces.  This
  can be revisited.

  FrontendAction gets a 'isModelParsingAction()' predicate function
  used to allow a new FrontendAction to recycle the Preprocessor
  and ASTContext.  This name could probably be made something
  more general (i.e., not tied to 'model files') at the expense
  of losing the intent of why it exists.  This can be revisited.

- This is a moderate sized patch; it has gone through some amount of
  offline code review.  Most of the changes to the non-analyzer
  parts are fairly small, and would make little sense without
  the analyzer changes.

- Most of the analyzer changes are plumbing, with the interesting
  behavior being introduced by ModelInjector.cpp and
  ModelConsumer.cpp.

- The new functionality introduced by this change is off-by-default.
  It requires an analyzer config option to enable.

Significantly fix Clang's header search for Ubuntu (and possibly other
modern Debian-based distributions) due to on-going multiarch madness.

It appears that when the multiarch heeader search support went into the
clang driver, it went in in a quite bad state. The order of includes
completely failed to match the order exhibited by GCC, and in a specific
case -- when the GCC triple and the multiarch triple don't match as with
i686-linux-gnu and i386-linux-gnu -- we would absolutely fail to find
the libstdc++ target-specific header files.

I assume that folks who have been using Clang on Ubuntu 32-bit systems
have been applying weird patches to hack around this. I can't imagine
how else it could have worked. This was originally reported by a 64-bit
operating system user who had a 32-bit crosscompiler installed. We tried
to use that rather than the bi-arch support of the 64-bit compiler, but
failed due to the triple differences.

I've corrected all the wrong orderings in the existing tests and added
a specific test for the multiarch triple strings that are different in
a significant way. This should significantly improve the usability of
Clang when checked out vanilla from upstream onto Ubuntu machines with
an i686 GCC installation for whatever reason.

10 years agoWin64 ABI shouldn't extend integer type arguments.
Julien Lerouge [Tue, 26 Aug 2014 21:52:27 +0000 (21:52 +0000)]
Win64 ABI shouldn't extend integer type arguments.

Summary:
MSVC doesn't extend integer types smaller than 64bit, so to preserve
binary compatibility, clang shouldn't either.

For example, the following C code built with MSVC:

unsigned test(unsigned v);
unsigned foobar(unsigned short);
int main() { return test(0xffffffff) + foobar(28); }

Produces the following:

  0000000000000004: B9 FF FF FF FF     mov         ecx,0FFFFFFFFh
  0000000000000009: E8 00 00 00 00     call        test
  000000000000000E: 89 44 24 20        mov         dword ptr [rsp+20h],eax
  0000000000000012: 66 B9 1C 00        mov         cx,1Ch
  0000000000000016: E8 00 00 00 00     call        foobar

And as you can see, when setting up the call to foobar, only cx is overwritten.

If foobar is compiled with clang, then the zero extension added by clang means
the rest of the register, which contains garbage, could be used.

For example if foobar is:

unsigned foobar(unsigned short v) {
    return v;
}

Compiled with clang -fomit-frame-pointer -O3 gives the following assembly:

foobar:
  0000000000000000: 89 C8              mov         eax,ecx
  0000000000000002: C3                 ret

And that function would return garbage because the 16 most significant bits of
ecx still contain garbage from the first call.

With this change, the code for that function is now:

foobar:
  0000000000000000: 0F B7 C1           movzx       eax,cx
  0000000000000003: C3                 ret
