member count. The count returned by numStructUnionElements is the
number of initializers that will be consumed, not the number of members
to iterate through. Fixes PR2534.

Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.
llvm-svn: 54583
- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.
Still some more work to do (forthcoming)...
llvm-svn: 54533
- Change hardcoded assembly instructions to a use of 'opt' (still
waiting for someone to yell at me for this).
- Add some cases to cover behavior fixed by previous commit.

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.

- 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>

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
- 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>

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

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.
