Final phase of converting BlockDecls over to DeclContext. This is unfortunately a largish/complex diff, however it was necessry to pass all the current block tests.

llvm-svn: 57337

llvm-svn: 57332

This required changes to attach the compound statement later on (like we do for functions).

llvm-svn: 57304

- Modify BlockExpr to reference the BlockDecl.

This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?).

Still some follow-up work to finish this (forthcoming).

llvm-svn: 57298

A little more tweaking with StmtIterator and SizeOfAlignofExpr.  A recent commit actually introduced a regression, not fixed a bug.

llvm-svn: 57282

This also removes the ugly hack needed in CFG.cpp for subclassing DeclStmt to create a DeclStmt with one Decl*.

llvm-svn: 57275

Fixed a masked bug when iterating over the child expressions of SizeOfAlignOfTypeExpr.  This bug was unmasked by recent changes to StmtIterator.

llvm-svn: 57273

Serialization for OwningDeclGroupRefs now works.

llvm-svn: 57272

llvm-svn: 57271

llvm-svn: 57222

Modified DeclGroupRef to always load/store the internal pointer value as Decl*.  This hopefully will obviate any concerns with violating strict type-aliasing issues.

llvm-svn: 57213

llvm-svn: 57206

This patch precedes removing getDecl() DeclStmt::entirely.

llvm-svn: 57205

llvm-svn: 57204

Added PrintRawDeclStmt; use this method to print out DeclStmt instead of using PrintRawDecl (which falsely assumes DeclStmts have only one Decl).

which is checking for something that can be inconsistent with
what we can constant fold.

__builtin_constant_p properly, and add some scaffolding for
FloatExprEvaluator to eventually handle huge_val and inf.

llvm-svn: 57152

code.

 - Print size as number of elements times "sizeof(elt type)", not
   perfect but better than just printing the completely wrong type.

This is a temporary solution to help with the block rewriter (though it certainly has general utility).
Once DeclGroup's are implemented, this SourceLocation should be stored with it (since it applies to all the decls).

llvm-svn: 56985

 - Enabled for builtins which are always constant expressions
   (__builtin_huge_val*, __builtin_inf*, __builtin_constant_p,
   __builtin_classify_type, __builtin___CFStringMakeConstantString).

Added Builtin::Context::isConstantExpr.
 - Currently overly simply interface which only works for builtins
   whose constantexprness does not depend on their arguments.

CallExpr::isBuiltinConstantExpr now takes an ASTContext argument.

llvm-svn: 56983

fixes problems handling references of va_list, which happens on x86_64.
This fixes PR2841 and rdar://6252231

llvm-svn: 56809

by decaying __builtin_va_list's type when forming builtins.  On
x86-64 (and other targets) __builtin_va_list is a typedef for
an array.

llvm-svn: 56768

llvm-svn: 56749

Internally store the body of a BlockExpr using a Stmt* instead of a CompoundStmt*, and use the getBody() method to do the appropriate checking.  This both removes the type-punning warnings in Expr.cpp and also makes BlockExpr have more consistency checks against modifications to its body (via StmtIterator).

llvm-svn: 56710

Use a union instead of a bunch of magic casts to implement a variant.  This removes the type-punning errors for DeclGroup.

llvm-svn: 56708

Move VLA processing logic from LiveVariables to CFG construction.  This way all dataflow analyses "see" the VLA size expressions.
