Argyrios Kyrtzidis cfbfe78e9e De-ASTContext-ify DeclContext.
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

Chris Lattner d86a13e02e Improve error recovery in C++: when we hit 'implicit int' cases in C++,
these are usually because the parser was thoroughly confused.  In addition
to typing the value being declared as an int and hoping for the best, we
mark the value as invalid so we don't get chains of errors when it is
used downstream.  In C, implicit int actually is valid, so typing the thing
as int is good and marking it invalid is bad. :)

Eli Friedman 0b4af8f755 PR3009: Get rid of bogus warning for scalar compound literals.
This patch isn't quite ideal in that it eliminates the warning for 
constructs like "int a = {1};", where the braces are in fact redundant.  
However, that would have required a bunch of refactoring, and it's 
much less likely to cause confusion compared to redundant nested braces.

Chris Lattner c71d08bc22 fix PR4073 by making designated initializer checking code use
VerifyIntegerConstantExpression instead of isIntegerConstantExpr.
This makes it ext-warn but tolerate things that fold to a constant
but that are not valid i-c-e's.

There must be a bug in the i-c-e computation though, because it
doesn't catch this case even with pedantic.

This also switches the later code to use EvaluateAsInt which is
simpler and handles everything that evaluate does.

Douglas Gregor 221c9a5578 Fix a thinko in the pre-allocation strategy for structured initializer
lists. The code wasn't accounting for the distinction between the
top-level call to getStructuredSubobjectInit and later calls that
occur deeper in the hierarchy. This problem manifested itself as
over-allocation in cases where we have large arrays of small
structures (<rdar://problem/6707362>).

llvm-svn: 67452
2009-03-21 18:13:52 +00:00
Douglas Gregor 6d00c993f5 When building the structured initializer list, pre-allocate storage in
its vectors based on the subobject type we're initializing and the
(unstructured) initializer list. This eliminates some malloc thrashing
when parsing initializers (from 117 vector reallocations down to 0
when parsing Cocoa.h). We can't always pre-allocate the right amount
of storage, since designated initializers can cause us to initialize
in non-predictable patterns.

Douglas Gregor 07d8e3a500 Allow flexible array initializers that are not surrounded by
braces. We now build the appropriate fully-structured initializer list
for such things. Per PR3618, verified that we're getting the right

Chris Lattner 7ec0bb6bc0 ok, not as broken as I thought, just confusing. This allows

Douglas Gregor a9add4ea76 Fix a bug with designated initializers where we were stepping out of a
union subobject initialization before checking whether the next
initiailizer was actually a designated initializer. This led to
spurious "excess elements in union initializer" errors. Thanks to
rdivacky for reporting the bug!

Douglas Gregor aef040a28e When handling "the rest" of a designated array subobject, maybe sure
to tell it that it wasn't (directly) designated. This way, we unwind
back to the explicit initializer list properly rather than getting
stuck in the wrong subobject. Fixes llvm.org/PR3519

Douglas Gregor fc4f8a1834 Implement semantic analysis for the GNU flexible array initialization
extension. The interaction with designated initializers is a
bit... interesting... but we follow GNU's lead and don't permit too
much crazy code in this area.

Also, make the "excess initializers" error message a bit more
informative.
