Sebastian Redl 60876431b1 Correctly initialize Reader to null. 
llvm-svn: 107994
 2010-07-09 17:53:32 +00:00
Sebastian Redl f525a30d19 Really respect -chained-pch. 
llvm-svn: 107993
 2010-07-09 17:40:12 +00:00
Douglas Gregor 8ed0c0b99d Introduce -f{no-}spell-checking options to enable/disable 
spell-checking. By default, spell-checking is enabled for Clang
(obviously) but disabled in CIndex for performance reasons.

Sebastian Redl f4b0c4b946 Add a frontend option -chained-pch and don't pass an active PCH reader to the PCH writer if it is not set, preventing creation of chained PCH files. Since the reader is so far unused, effectively no functionality change. 
llvm-svn: 107936
 2010-07-09 00:00:58 +00:00
Sebastian Redl 595c51342c Some preparatory work for chained PCH. No functionality change.

Argyrios Kyrtzidis 7e8996c7e6 Introduce PCHReader::GetTranslationUnitDecl() and use it instead of ReadDeclRecord when initializing. 
ReadDeclRecord would hit assertion if the translation unit declaration was already loaded during
IdentifierInfo initialization.

Argyrios Kyrtzidis 9f2d24a808 Support TemplateTemplateParmDecl for PCH. 
llvm-svn: 107884
 2010-07-08 17:12:57 +00:00
Argyrios Kyrtzidis a4ed18191c For TagType and TemplateSpecializationType, isDependent calculation may be invalid because some decls that the 
calculation is using may still be initializing.
Thus, store the isDependent flag to PCH and restore directly to Type.

llvm-svn: 107873
 2010-07-08 13:09:53 +00:00
Argyrios Kyrtzidis 1985bb3b10 Read/write the C++ parts of DeclRefExpr and MemberExpr for PCH.

Argyrios Kyrtzidis 00dda6accc Fix reading of UsingDecl from PCH. 
llvm-svn: 107871
 2010-07-08 13:09:41 +00:00
Douglas Gregor 747eb7840a Reinstate the fix for PR7556. A silly use of isTrivial() was 
suppressing copies of objects with trivial copy constructors.

Douglas Gregor e182370eda Revert r107828 and r107827, the fix for PR7556, which seems to be 
breaking bootstrap on Linux.

llvm-svn: 107837
 2010-07-07 23:37:33 +00:00
Douglas Gregor 6df2b8c3ac Rename CXXZeroInitValueExpr to CXXScalarValueInitExpr, to reflect its 
newly-narrowed scope. No functionality change.

llvm-svn: 107828
 2010-07-07 22:43:56 +00:00
Chris Lattner 3e2ee147d0 add driver support for minix, patch by Kees van Reeuwijk 
from PR7583

llvm-svn: 107784
 2010-07-07 15:46:30 +00:00
Argyrios Kyrtzidis 903ccd6121 Delay passing InterestingDecls to the Consumer until when we know we are not in recursive loading and the 
declarations are fully initialized.

llvm-svn: 107783
 2010-07-07 15:46:26 +00:00
Argyrios Kyrtzidis 46f556d4e5 Simplify code. FunctionDecl and ObjCMethodDecl have some common interfaces. 
llvm-svn: 107769
 2010-07-07 11:31:23 +00:00
Tom Care 3ff08a8e76 Added a path-sensitive idempotent operation checker (-analyzer-idempotent-operation). Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect. 
Example:
{
int a = 1;
int b = 5;
int c = b / a; // a is 1 on all paths
}

- New IdempotentOperationChecker class
- Moved recursive Stmt functions in r107675 to IdempotentOperationChecker
- Minor refactoring of SVal to allow checking for any integer
- Added command line option for check
- Added basic test cases

Duncan Sands 1614396b15 Pacify versions of gcc that think these variables may be used 
uninitialized (which doesn't seem to be the case), by giving
them arbitrary initial values.

Argyrios Kyrtzidis b5fcdc21c2 Fix a regression of a previous commit of mine (rdar://8158953). 
Some of the invariant checks for creating Record/Enum types don't hold true during PCH reading.
Introduce more suitable ASTContext::getRecordType() and getEnumType().

llvm-svn: 107598
 2010-07-04 21:44:47 +00:00
Argyrios Kyrtzidis 6685e8a747 Read/write more information of ASTContext for PCH. Overriden methods and instantiated-from information. 
llvm-svn: 107597

Argyrios Kyrtzidis e862cbc5f6 Don't try to install the __[u]int128_t identifier if it is already installed by PCHReader. 
Currently, adding it to visible decls of a PCH'ed translation unit has no effect because
adding visible decls before deserialization has no effect (the decls won't be visible).
This will be fixed in a future commit; then it will force deserialization of visible decls, so avoid pointlessly installing it.

Argyrios Kyrtzidis dae2a1607e When setting the anonymous namespace at PCH reading, it may still be initializing so avoid

Douglas Gregor 9672f92f7f Lazily declare default constructors. We now delay the construction of 
declarations for implicit default constructors, copy constructors,
copy assignment operators, and destructors. On a "simple" translation
unit that includes a bunch of C++ standard library headers, we
generate relatively few of these implicit declarations now:

  4/159 implicit default constructors created
  18/236 implicit copy constructors created
  70/241 implicit copy assignment operators created
  0/173 implicit destructors created

And, on this translation unit, this optimization doesn't really
provide any benefit. I'll do some more performance measurements soon,
but this completes the implementation work for <rdar://problem/8151045>.
