type.
- This generates somewhat less optimal code than before but this is
not hard to rectify once stable (at the cost of slightly more
complex code).
- This currently always uses little-endian ordering of the bitfield.
- This breaks the CodeGen/bitfield.c test because it was grepping for
hard-coded assembly instructions. Will fix once a better test case
is constructed (hard to do without execution).
- This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c
and Regression/C/PR1386.c from the test suite.

llvm-svn: 54395
- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr -
ptr) so that implementation matches that of other operators.
- Modify EmitCompoundAssign to compute and perform the appropriate
casts of left, right, and result types for the assorted pointer
arithmetic cases.
- Fix EmitSub (ptr - int) case to negate the rhs *after*
extension. This is critical when the rhs is unsigned (and needs
extension).
- This fixes cfrac.

scimark2 on Darwin.
- Added Sema support for asm-label on variables, which I forgot before.
- Update CodeGen to use GlobalDeclMap to determine if static Decls
require emission (instead of LLVM module name lookup). Important
since the Decl name and the LLVM module name can differ.
- <rdar://problem/6116729>
llvm-svn: 54388
having multiple bindings from all the possible decls which
conceptually map to the same global).
- This eliminates CodeGen depending on the LLVM module for name
lookup.
- This also eliminates the need for ReplaceMapValuesWith (hurrah).
- This handles lookups for FunctionDecls correctly in the presence of
aliases, this was previously broken.
- WIP: Can still clean up & unify variable and function emission.
llvm-svn: 54382
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead. Will update other clients after additional testing.
llvm-svn: 54368
- ActOnDeclarator now takes an additional parameter which is the
AsmLabel if used. Its unfortunate that this bubbles up this high,
but we cannot just lump it in as an attribute without mistakenly
*accepting* it as an attribute.
- The actual asm-label itself is, however, encoded as an AsmLabelAttr
on the FunctionDecl.
- Slightly improved parser error recovery on malformed asm-labels.
- CodeGen support still missing...
llvm-svn: 54339
- Like EXTENSION but always generates a warning (even without
-pedantic).
- Updated ptr -> int, int -> ptr, and incompatible cast warnings to
be EXTWARN.
- Other EXTENSION level diagnostics should be audited for upgrade.
- Updated several test cases to fix code which produced unanticipated
warnings.
llvm-svn: 54335
- Follows emission scheme used by llvm-gcc, i.e. invent an id for
each label whose address is taken and replace each indirect goto by
a switch to each possible target.
- Currently we emit a switch for each indirect goto instead of
merging them as llvm-gcc does.
llvm-svn: 54318
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).
Fixing this greatly simplifies getArrayDecayedType, which is a good sign.
llvm-svn: 54317
- There is an miscompilation issue remaining due to a poor
interaction between the delayed emission of static functions and
the emission of constructors, but that already existed prior to
this change.
llvm-svn: 54258
instead of mapping the decl to a bitcast of the global to the correct
type.
- GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now.
- This solves a problem where a dangling pointer could be introduced
by the RAUW done when replacing a forward or tentative
definition. See testcase for more details.
- Fixes <rdar://problem/6108358>
llvm-svn: 54211
- No (intended) functionality change.
- Primary purpose is to clearly separate (lazy) construction of
globals that are a forward declaration or tentative definition from
those that are the final definition.
- Lazy construction is now encapsulated in
GetAddrOf{Function,GlobalVar} while final definitions are
constructed in EmitGlobal{Function,Var}Definition.
- External interface for dealing with globals is now limited to
EmitGlobal and GetAddrOf{Function,GlobalVar}.
- Also updated helper functions dealing with statics, annotations,
and ctors to be private.

1) reject stuff like "id<foo> short" and "<foo> short". 2) set
the declspec range correctly 3) only parse protocol qualifiers
when in objc mode.
llvm-svn: 54086
First, fix canonical type handling of these, since protocol qualified id's are always
canonical. Next, enhance SemaType to actually make these when used (instead of int)
allowing them to actually be used when appropriate. Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's. This fixes
rdar://5986251
llvm-svn: 54083
like "id<foo>". This 1) fixes an infinite loop in the parser on things
like "short<foo>" 2) emits a warning about this bogus construct and 3)
changes the testcase to be substantially reduced.

problem with &&/||. 2) use canonical types for comparison instead
of raw types. 3) emit an ext-warn for a gnu extension.
Also simplify the code to make it less nested.
llvm-svn: 54068
(a) removes a bogus warning.
(b) removes an undesirable usage of the ObjCMessageExpr constructor that takes an IdentifierInfo * (which I will abolish).

t2.c:1:17: warning: hexadecimal floating constants are a C99 feature

instead of emitting a weird error message that doesn't make sense:

long double d = 0x0.0000003ffffffff00000p-16357L;

llvm-svn: 54035
- Fix multiple issues with the way case ranges were emitted, see test
cases details about the specific issues.
- The root issue was not being careful about how basic blocks were
emitted which led to them being chained together incorrectly,
resulting in improper control flow.
- Fixes <rdar://problem/6098585>
llvm-svn: 54006
This fixes a critical rewriter bug (<rdar://problem/6096760> clang ObjC rewriter: 'self' not expected value in class method called with 'super').
Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr).
llvm-svn: 53994
- Also cleaned up emission slightly
- Inspection of the code revealed several other bugs, however. Case
ranges are not properly wired and can result in switch cases being
dropped or even infinite loops. See: <rdar://problem/6098585>
Completes: <rdar://problem/6094119>

This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

of a specific smallvector size.
Fix protocol lists to pass down proper location info, so we get diagnostics
like this:
t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^
instead of this:
t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>

Add a new IdentifierLocPair typedef which is just a pair<IdentifierInfo*, SourceLocation>
llvm-svn: 53883
the standard "set these as the list of protocols" interface instead of a
strange "set this as the size and then set each one to the value" interface.
The problem with the later is that it a) is completely different from
everything else, b) is awkward, and c) doesn't handle the case when a
referenced protocol is invalid: it set it to null.
This meant that all clients downstream would have to handle null protocols
in the protocol list, and empirically they didn't. Fix this by not setting
invalid protocols in the referenced protocol list, fixing the crash on
test/Sema/objc-interface-1.m
While I'm at it, clean up some locations so that we produce:
t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
~~~~~~~~~~~~~~~~~~~~~ ^

t.m:1:1: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'

valid to just cast to a pointertype. We have to handle typedefs etc
