Douglas Gregor d42a0fb41b Upgrade the "excess elements in array initializer" warning to an 
error, since both C99 and C++ consider it an error. For reference, GCC
makes this a warning while G++ makes it an error.

Anders Carlsson 221483dd4e Make sure to cast the VLA size of array to the type of size_t. Fixes PR3442.

Douglas Gregor 0202cb406e Introduce a new expression node, ImplicitValueInitExpr, that 
represents an implicit value-initialization of a subobject of a
particular type. This replaces the (ab)use of CXXZeroValueInitExpr
within initializer lists for the "holes" that occur due to the use of
C99 designated initializers.

The new test case is currently XFAIL'd, because CodeGen's
ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be
taught to value-initialize when it sees ImplicitValueInitExprs.

Daniel Dunbar 74f2425b89 Evaluate ==,!= for complex types.

 2009-01-29 06:43:41 +00:00
Daniel Dunbar f50e60b23a Implement basic _Complex integer constant folding. 
- Merged into single ComplexEvaluator, these share too much logic to
   be worth splitting for float/int (IMHO). Will split on request.

Nuno Lopes bb537dc189 fix PR3427: fix debuginfo for incomplete array types 
llvm-svn: 63158
 2009-01-28 00:35:17 +00:00
Anders Carlsson 570c357ded If an input constraint refers to an output constraint, it should have the same constraint info as the output constraint. Fixes PR3417

Eli Friedman c69d454d5a Make the constant folder aware of 
__builtin___CFStringMakeConstantString.  (We get into trouble in 
GenerateStaticBlockVarDecl if the constant folder isn't accurate.)

Eli Friedman 529a99bcf4 Fix the address of a label to be properly considered and emitted as a 
constant.

 2009-01-25 01:21:06 +00:00
Eli Friedman 8549e5dcc8 Fix for PR2910: implement CodeGen for non-constant offsetof. 
Note that there are still other issues in this area; see PR3396.

 2009-01-24 22:38:55 +00:00
Daniel Dunbar 42a8cd37b2 Handle pointer arithmetic on function pointers. 
- <rdar://problem/6518844> Clang-generated bitcode crashes LLVM while compiling function pointer addition expression

llvm-svn: 62857
 2009-01-23 18:51:09 +00:00
Daniel Dunbar 56493b0d54 Allow creation of "dummy" compile units for debug information. 
- Although gross, this is needed currently to ensure that we produce
   well formed debug information (to match pace with the assertions
   being added to DebugInfo in LLVM).

Anders Carlsson 762e162284 Fix the bug that would cause Python to crash at startup. 
When emitting the static variables we need to make sure that the order is preserved. 
Fix this by making StaticDecls a std::list which has O(1) random removal.

Eli Friedman f4084708cd Make VLAs usable, and make basic usage work correctly. Also, add a 
simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.

Daniel Dunbar 9b1335eca8 Fix redundant load of bit-fields on assignment (to get the updated 
value).
 - Use extra argument to EmitStoreThroughLValue to provide place to
   write update bit-field value if caller requires it.
