Ted Kremenek 915542850b Change CXTranslationUnit to not directly cast to an ASTUnit*,
but to wrap both an ASTUnit and a "string pool"
that will be used for fast USR generation.

This requires a bunch of mechanical changes, as
there was a ton of code that assumed that CXTranslationUnit
and ASTUnit* were the same.

Along with this change, introduce CXStringBuf,
which provides an llvm::SmallVector<char> backing
for repeatedly generating CXStrings without a huge
amount of malloc() traffic.  This requires making
some changes to the representation of CXString
by renaming a few fields (but keeping the size
of the object the same).

Douglas Gregor c65929299d Tweak libclang's heuristics for building precompiled preambles and
caching global code-completion results. In particular, don't perform
either operation the first time we parse, but do both after the first
reparse.

Douglas Gregor 229bebdeb5 ntroduce clang_getSpellingLocation() into libclang, to provide the
location where we're spelling a token even within a
macro. clang_getInstantiationLocation() tells where we instantiated
the macro.

I'm still not thrilled with the CXSourceLocation/CXSourceRange APIs,
since they gloss over macro-instantiation information.

Take 2: this time, adjusted tests appropriately and used a "simple"
approach to the spelling location.

Francois Pichet 85e6da1f19 This patch remove the Win32 XFAIL from remap-complete.c
The problem was that text files were open in text mode and Microsoft implementation of fread and write will try to do nasty line-feed conversion which make the line position no longer valid. The fix is to read and write files in binary mode.

Douglas Gregor 36e3b5c79e Switch c-index-test from clang_codeComplete() over to
clang_codeCompleteAt(). This uncovered a few issues with the latter:

  - ASTUnit wasn't saving/restoring diagnostic state appropriately between
    reparses and code completions.
  - "Overload" completions weren't being passed through to the client

Douglas Gregor 7845f1e80e Eliminate clang_setUseExternalASTGeneration() from libclang. Between
improvements to the compiler and the introduction of crash recovery,
it no longer makes sense to allow this mode. Moreover, this eliminates
one use of the "clang" executable from within libclang; we'd like them
all to go away.

Douglas Gregor 16a2bdd6b0 Introduce a new kind of cursor into libclang, which covers a reference
to an "overloaded" set of declarations. This cursor kind works for

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.

2010-08-05 09:09:23 +00:00
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).
