Douglas Gregor 3998219789 Extend the code-completion caching infrastructure to include global
declarations (in addition to macros). Each kind of declaration maps to
a certain set of completion contexts, and the ASTUnit completion logic
introduces the completion strings for those declarations if the actual
code-completion occurs in one of the contexts where it matters. 

There are a few new code-completion-context kinds. Without these,
certain completions (e.g., after "using namespace") would need to
suppress all global completions, which would be unfortunate.

Note that we don't get the priorities right for global completions,
because we don't have enough type information. We'll need a way to
compare types in an ASTContext-agnostic way before this can be
implemented.

Ted Kremenek aa01481d78 Always recurse into sub-cursors when annotating tokens, as this information is used for annotating macro arguments. This finishes up <rdar://problem/8044584>.
llvm-svn: 111066
2010-08-14 02:50:46 +00:00
Ted Kremenek f4ade0ae3f As a heuristic, annotate tokens (via clang_annotateTokens) that are the arguments of a macro instantiation using the closest cursor with the same spelling location. Because macro arguments can get token pasted in any arbitrary order, we use the annotation map to paper over the token -> cursor annotations during our post-processing stage. This fixes most of <rdar://problem/8044584>, but still doesn't work for assert().

Douglas Gregor b14904c4a8 Implement caching of code-completion results for macro definitions
when the CXTranslationUnit_CacheCompletionResults option is given to
clang_parseTranslationUnit(). Essentially, we compute code-completion
results for macro definitions after we have parsed the file, then
store an ASTContext-agnostic version of those results (completion
string, cursor kind, priority, and active contexts) in the
ASTUnit. When performing code completion in that ASTUnit, we splice 
the macro definition results into the results provided by the actual
code-completion (which has had macros turned off) before libclang gets
those results. We use completion context information to only splice in
those results that make sense for that context.

With a completion involving all of the macros from Cocoa.h and a few other
system libraries (totally ~8500 macro definitions) living in a
precompiled header, we get about a 9% performance improvement from
code completion, since we no longer have to deserialize all of the
macro definitions from the precompiled header. 

Note that macro definitions are merely the canary; the cache is
designed to also support other top-level declarations, which should be
a bigger performance win. That optimization will be next.

Note also that there is no mechanism for determining when to throw
away the cache and recompute its contents.

Douglas Gregor 8e984da800 Add code-completion support directly to ASTUnit, which performs code
completion within the translation unit using the same command-line
arguments for parsing the translation unit. Eventually, we'll reuse
the precompiled preamble to improve code-completion performance, and
this also gives us a place to cache results.

Expose this function via the new libclang function
clang_codeCompleteAt(), which performs the code completion within a
CXTranslationUnit. The completion occurs in-process
(clang_codeCompletion() runs code completion out-of-process).

Douglas Gregor e9db88f991 When using a precompiled preamble, keep track of the top-level
declarations that we saw when creating the precompiled preamble, and
provide those declarations in addition to the declarations parsed in

makes the use of precompiled preambles a pure optimization, rather
than changing the semantics of the parsed translation unit.

Argyrios Kyrtzidis 4fac280618 Merge PCHWriterDecl.cpp's isRequiredDecl and CodeGenModule::MayDeferGeneration into a new function,
DeclIsRequiredFunctionOrFileScopedVar.

This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also
needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes.
This fixes current (and avoids future) codegen-from-PCH bugs.

Douglas Gregor cd8bdd025f Improve performance during cursor traversal when a region of interest
is present. 

Rather than using clang_getCursorExtent(), which requires
us to lex the token at the ending position to determine its
length. Then, we'd be comparing [a, b) source ranges that cover the
characters in the range rather than the normal behavior for Clang's
source ranges, which covers the tokens in the range. However, relexing
causes us to read the source file (which may come from a precompiled
header), which is rather unfortunate and affects performance.

In the new scheme, we only use Clang-style source ranges that cover
the tokens in the range. At the entry points where this matters
(clang_annotateTokens, clang_getCursor), we make sure to move source
locations to the start of the token.

Addresses most of <rdar://problem/8049381>.

Chris Lattner ed8b6b799d introduce a new CharSourceRange class, and enhance the diagnostics routines
to use them instead of SourceRange.  CharSourceRange is just a SourceRange
plus a bool that indicates whether the range has the end character resolved
or whether the end location is the start of the end token.  While most of
the compiler wants to think of ranges that have ends that are the start of
the end token, the printf diagnostic stuff wants to highlight ranges within
tokens.

This is transparent to the diagnostic stuff.  To start taking advantage of
the new capabilities, you can do something like this:
  Diag(..) << CharSourceRange::getCharRange(Begin,End)

Alexis Hunt 344393e9cf Implement first TD-based usage of attributes.
Currently, there are two effective changes:

 - Attr::Kind has been changed to attr::Kind, in a separate namespace
   rather than the Attr class. This is because the enumerator needs to
   be visible to parse.
 - The class definitions for the C++0x attributes other than aligned are
   generated by TableGen.

The specific classes generated by TableGen are controlled by an array in
TableGen (see the accompanying commit to the LLVM repository). I will be
expanding the amount of code generated as I develop the new attributes system
while initially keeping it confined to these attributes.

Daniel Dunbar c1b1729b66 Break Frontend's dependency on Rewrite, Checker and CodeGen in shared library configuration
Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen.  This is suboptimal for
clients which only wish to make use of the frontend.  CodeGen in
particular introduces a large number of unwanted dependencies.

This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries.  The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).

After applying this patch, Clang builds correctly using CMake and

Daniel Dunbar 6f8362c6bf Frontend: Add CodeGenAction support for handling LLVM IR.
- This magically enables using 'clang -cc1' as a replacement for most of 'llvm-as', 'llvm-dis', 'llc' and 'opt' functionality.

For example, 'llvm-as' is:
  $ clang -cc1 -emit-llvm-bc FOO.ll -o FOO.bc
and 'llvm-dis' is:
  $ clang -cc1 -emit-llvm    FOO.bc -o -
and 'opt' is, e.g.:
  $ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
  $ clang -cc1 -S -o - FOO.ll

The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

2010-05-17 20:06:56 +00:00
John McCall 8b07ec253d Substantially alter the design of the Objective C type AST by introducing
ObjCObjectType, which is basically just a pair of
  one of {primitive-id, primitive-Class, user-defined @class}
with
  a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared).  ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType.  Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet.  Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

2010-04-29 17:43:26 +00:00
Douglas Gregor 882211c1da Completely reimplement __builtin_offsetof, based on a patch by Roberto
Amadini.

This change introduces a new expression node type, OffsetOfExpr, that
describes __builtin_offsetof. Previously, __builtin_offsetof was
implemented using a unary operator whose subexpression involved
various synthesized array-subscript and member-reference expressions,
which was ugly and made it very hard to instantiate as a
template. OffsetOfExpr represents the AST more faithfully, with proper
type source information and a more compact representation.

OffsetOfExpr also has support for dependent __builtin_offsetof
expressions; it can be value-dependent, but will never be
type-dependent (like sizeof or alignof). This commit introduces
template instantiation for __builtin_offsetof as well.

There are two major caveats to this patch:

  1) CodeGen cannot handle the case where __builtin_offsetof is not a
  constant expression, so it produces an error. So, to avoid
  regressing in C, we retain the old UnaryOperator-based
  __builtin_offsetof implementation in C while using the shiny new
  OffsetOfExpr implementation in C++. The old implementation can go
  away once we have proper CodeGen support for this case, which we
  expect won't cause much trouble in C++.

  2) __builtin_offsetof doesn't work well with non-POD class types,
  particularly when the designated field is found within a base
  class. I will address this in a subsequent patch.

Fixes PR5880 and a bunch of assertions when building Boost.Python
tests.

Douglas Gregor 9a12919421 Overhaul the AST representation of Objective-C message send
expressions, to improve source-location information, clarify the
actual receiver of the message, and pave the way for proper C++
support. The ObjCMessageExpr node represents four different kinds of
message sends in a single AST node:

  1) Send to a object instance described by an expression (e.g., [x method:5])
  2) Send to a class described by the class name (e.g., [NSString method:5])
  3) Send to a superclass class (e.g, [super method:5] in class method)
  4) Send to a superclass instance (e.g., [super method:5] in instance method)

Previously these four cases where tangled together. Now, they have
more distinct representations. Specific changes:

  1) Unchanged; the object instance is represented by an Expr*.

  2) Previously stored the ObjCInterfaceDecl* referring to the class
  receiving the message. Now stores a TypeSourceInfo* so that we know
  how the class was spelled. This both maintains typedef information
  and opens the door for more complicated C++ types (e.g., dependent
  types). There was an alternative, unused representation of these
  sends by naming the class via an IdentifierInfo *. In practice, we
  either had an ObjCInterfaceDecl *, from which we would get the
  IdentifierInfo *, or we fell into the case below...

  3) Previously represented by a class message whose IdentifierInfo *
  referred to "super". Sema and CodeGen would use isStr("super") to
  determine if they had a send to super. Now represented as a
  "class super" send, where we have both the location of the "super"
  keyword and the ObjCInterfaceDecl* of the superclass we're
  targetting (statically).

  4) Previously represented by an instance message whose receiver is a
  an ObjCSuperExpr, which Sema and CodeGen would check for via
  isa<ObjCSuperExpr>(). Now represented as an "instance super" send,
  where we have both the location of the "super" keyword and the
  ObjCInterfaceDecl* of the superclass we're targetting
  (statically). Note that ObjCSuperExpr only has one remaining use in
  the AST, which is for "super.prop" references.

The new representation of ObjCMessageExpr is 2 pointers smaller than
the old one, since it combines more storage. It also eliminates a leak
when we loaded message-send expressions from a precompiled header. The
representation also feels much cleaner to me; comments welcome!

This patch attempts to maintain the same semantics we previously had
with Objective-C message sends. In several places, there are massive
changes that boil down to simply replacing a nested-if structure such
as:

  if (message has a receiver expression) {
    // instance message
    if (isa<ObjCSuperExpr>(...)) {
     // send to super
    } else {
     // send to an object
   }
  } else {
    // class message
    if (name->isStr("super")) {
      // class send to super
    } else {
      // send to class
    }
  }

with a switch

  switch (E->getReceiverKind()) {
  case ObjCMessageExpr::SuperInstance: ...
  case ObjCMessageExpr::Instance: ...
  case ObjCMessageExpr::SuperClass: ...
  case ObjCMessageExpr::Class:...
  }

There are quite a few places (particularly in the checkers) where
send-to-super is effectively ignored. I've placed FIXMEs in most of
them, and attempted to address send-to-super in a reasonable way. This
could use some review.
