Ted Kremenek 1daa3cfbae TargetInfo no longer includes a reference to SourceManager.
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

Ted Kremenek d4e5fbacab Mega-patch: ripped SourceManager out of Diagnostic/DiagnosticClient. Now
SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

Steve Naroff 205ec3d07a Yesterday, I simplified how we stream top-level decls.
After a discussion with Ted, we both came to the conclusion that adding a "HandleTopLevelDeclaration" hook to ASConsumer is far more elegant. The default implementation of HandleTopLevelDeclaration will be responsible for iterating over the ScopedDecl (which has a chain of the decls:-).

TODO: Once Ted adds HandleTopLevelDeclaration, make sure TagDecls are chainged appropriately...

Steve Naroff 197616c3a8 Several fixes/simplifications surrounding how we stream top-level decl AST's.
The following code...

typedef struct cssm_data {} CSSM_DATA, *CSSM_DATA_PTR;

struct Y { int A; };

struct X { int A; } D; 

struct X E, F;

...now produces the following output...

> ../../Debug/bin/clang xx.c -ast-print
Read top-level tag decl: 'cssm_data'
typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data *CSSM_DATA_PTR;
Read top-level tag decl: 'Y'
Read top-level tag decl: 'X'
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'F'

...which is much more accurate than the previous -ast-print output...

typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data CSSM_DATA;
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'E'

Steve Naroff 6d40db0dde Implement a more sensible strategy for ObjC built-in types (addressing a long standing FIXME in Sema::GetObjcIdType()).
This removes several gross hacks to work around the previous "lazy" behavior.

Two notes:
- MinimalActions still needs to be taught about the built-in types (This breaks one of the -noop test cases). I started this, then added a FIXME.
- I didn't convert Sema::GetObjcProtoType() yet.

Steve Naroff 783a7a0698 Refinements to Sema::GetObjcIdType()...
- Cache the typedef, not the type (avoids importing AST/Type.h).
- Emit an error if "id" cannot be found.
- Comment the routine and add a FIXME to reconsider how we emulate GCC's new fangled behavior. This isn't a priority for now, since almost no code depends on having "id" built-in.
- Add a test.

This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added).

Added Action::ActOnTranslationUnitScope() and renamed Action::PopScope to ActOnPopScope.

Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped).

Chris Lattner b87b1b36ee initial support for checking format strings, patch by Ted Kremenek:
"I've coded up some support in clang to flag warnings for non-constant format strings used in calls to printf-like functions (all the functions listed in "man fprintf").  Non-constant format strings are a source of many security exploits in C/C++ programs, and I believe are currently detected by gcc using the flag -Wformat-nonliteral."

Chris Lattner 23b7eb677d Finally bite the bullet and make the major change: split the clang namespace
out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

An important, but truly mind numbing change.

Added 6 flavors of Sema::Diag() that take 1 or two SourceRanges. Considered
adding 3 flavors (using default args), however this wasn't as clear.

Removed 2 flavors of Sema::Diag() that took LexerToken's (they weren't used).

Changed all the typechecking routines to pass the appropriate range(s).

Hacked the diagnostic machinery and driver to acccommodate the new data.

What's left? A FIXME in clang.c to use the ranges. Chris offered to do the
honors:-) Which includes taking us to the end of an identifier:-)

- Converted the unary check functions (ParseUnaryOp and friends) to have
the same API as their binary counterparts.
- Implemented CheckIndirectionOperand (was stubbed). While testing, noticed
that Expr::isModifiableLvalue was incomplete (fixed and referenced draft).
- Added constantOne instance variable to Sema.
- Removed CheckArithmeticOperand (the code was so simple that it is now
part of ParseUnaryOp). The name wasn't great anyway:-)

-Changed the name of TypeRef to QualType. Many diffs.
-Changed the QualType constructor to require Quals be passed. This makes the code a bit
more verbose, however will make the code easier to work on. Given the complexity
of types, this should help spot bogosities.
-Changed the Expr constructor to require a QualType. Same motivation.

Steve Naroff bc2f0993c0 Bug #:
Submitted by:
Reviewed by:
Implement ++/-- typechecking for pre/post unary expressions. This includes:

- added isLvalue, isModifiableLvalue (on TypeRef, Type, and RecordType).
- added isRealType, isRealFloatingType, isComplexType.
- hacked Diag to take a TypeRef (I was sick of writing the 2 line "setup":-)
In addition, this will likely lead to less bugs...I already had written code
that was doing a getAsString on "Type" (which is wrong...since it doesn't include
any qualifiers).
- Changed UnaryOperator to take a TypeRef...pass it the right stuff.
- Removed redundant ternary expressions in several predicates.
- A couple diagnostics.

Type Checking...round 2. This checkin "breaks" parsing carbon.h. I imagine
that this will be true for the next week or so. Nevertheless, this round of
changes includes the following:

- Hacked various Expr classes to pass the appropriate TypeRef. Still have
a few more classes to touch.
- Implement type checking for ParseArraySubscriptExpr and ParseMemberReferenceExpr.
- Added a debug hook to derive the class name for Stmt/Expr nodes. Currently a
linear search...could easily optimize if important.
- Changed the name of TaggedType->TagType. Now we have TagType and TagDecl (which
are easier to remember).
- Fixed a bug in StringLiteral conversion I did a couple weeks ago. hadError was
not initialized (oops).
- changed Sema::Diag to return true. This streamlines the type checking code
considerably.
- Added many diagnositics.

This should be it!

More code to parse numeric constants. This checkin includes:
- Feedback from Chris.
- Support for parsing floating point constants.
- Moved the code to "Sema". Changed API in Action.
- More/better error diagnostics.

is to work on filling in sensible values (in IntegerLiteral/FloatLiteral).

Steve Naroff 2c055d2b2b Go back to having the clang driver create ASTContext explicitly, passing
it to Sema/ASTStreamer (separating the lifetime of ASTContext from
the lifetime of Sema). One day it might be useful to consider creating
a context object implicitly if one isn't provided (using default arguments in
Sema's constructor). At this point, adding this convenience isn't necessary.

2007-02-28 19:32:13 +00:00
Steve Naroff 38d31b47b0 Make Sema's use of the preprocessor explicit (rather than assume
the prerocessor will be available via ASTContext).
- Removed the public data member "PP" in ASTContext.
- Changed ASTContext's contructor to take TargetInfo/IdentifierTable explicitly.
- Implicitly create an ASTContext in Sema's constructor. This simplifies
the clients job (and makes ASTContext more private).
--As a side effect, added a "PrintStats" hook to Sema.

To support this level of encapsulation, ASTContext is always dynamically
allocated (by Sema). Previously, ASTContext was being allocated on the
stack. I don't believe this should be a performance issue (since ASTContext
is fairly course grain and tied to the lifetime of Sema currently).
