Steve Naroff 7a147c6a3c Remove support for BlockExprExpr. For example...
^(expression) or ^(int arg1, float arg2)(expression)
...is no longer supported. 
All block literals now require a compound statement.

Eli Friedman de09ce03c4 Fix for PR2747: allow pointer->int casts with a null base; these are
offset-of-like expressions.

Eli Friedman 7c9ba6a1e3 An extremely hacky version of transparent_union support; it isn't
anywhere near correct in terms of missing cases and missing 
diagnostics, but it's good enough to handle the uses in the 
Linux system headers, which are currently a constant pain for compiling 
applications on Linux.

Eli Friedman e7175d83dc Make sure to take the unqualified versions of the canonical types for
type-checking pointer subtraction; if the canonical types aren't used,
the qualifiers won't always get stripped off correctly.

Eli Friedman 4c55e2c4ed Backing out r55607 due to logic errors and test regression.
I'll try to come up with a correct fix for the testcase sometime soon.

Ted Kremenek c4f6d90ba1 Tidy up sema processing of attribute "nonull":
- warn about nonnull being applied to functions with no pointer arguments
- continue processing argument list in the attribute when we encounter a non-pointer parameter being marked as nonnull
- when no argument list is specified, only mark pointers as nonnull.  This fixes PR 2732 and radar 6188814.

Eli Friedman 0a2ba3f10b Fix for PR2720; be a little bit more permissive in initializers for
casting pointers to integers.

Eventually, we should check whether we can evaluate an expression 
using Expr::tryEvaluate, and this codepath should be tightened to only 
handle standard-compliant cases.

2008-08-10 01:58:45 +00:00
Eli Friedman a3b2f6f2af Make sure to count the struct elements correctly; here, we want the
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.

llvm-svn: 54601

Steve Naroff 239255d2a6 Fix Sema::MergeVarDecl() to better handle type compatibility. The previous code was trying to handle arrays specially (which didn't work for pointers to array). Removed local helper function areEquivalentArrayTypes(), replacing it's use with the more general ASTContext::typesAreCompatible() predicate.
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
2008-08-09 16:04:40 +00:00
Steve Naroff 5bb8f2264b Fix issues with C "tentative" definitions.
- 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)...

Daniel Dunbar 81f7f2904c Add EXTWARN Diagnostic class.
- 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.

Daniel Dunbar b692ef405b Fix several issues in checking of address-of expressions.
- clang was erroneously accepting address-of applied to lvalue
   expressions involving pointer arithmetic.
 - clang was erroneously rejecting address-of applied to deref
   expressions of pointer-typed variables.
 - Improved existing test case.
 - Fixes: <rdar://problem/6113867>, <rdar://problem/6080158>
