Douglas Gregor 133edddd82 Devirtualize Decl::getNextRedeclaration(). 
llvm-svn: 125740
 2011-02-17 08:47:29 +00:00
Chandler Carruth 712563bba4 Implement -Wenum-compare, which warns when comparing two enums of 
different types. We omit the warning when the enum types are anonymous.
Unlike GCC, this warning does not distinguish between C++ and C/ObjC for
controling whether it is on by default, it is always on by default.

Original patch contributed by Richard Trieu (@ Google), I fixed some
style issues, and cleaned it up for submission.

Chris Lattner c8e630e4db Step #1/N of implementing support for __label__: split labels into 
LabelDecl and LabelStmt.  There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself.  This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.

This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.

This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.

Review appreciated, particularly for the cindex and template bits.

Douglas Gregor b0f2ea9e9e When printing a qualified type, look through a substituted template 
parameter type to see what's behind it, so that we don't end up
printing silly things like "float const *" when "const float *" would
make more sense. Also, replace the pile of "isa" tests with a simple
switch enumerating all of the cases, making a few more obvious cases
use prefix qualifiers.

John McCall bf9a86b50f Don't call objc_read_weak as part of emitting a block literal. 
Nobody ever gave me a clear reason for why we were doing this, and
now it's apparently causing serious problems, so if *not* having this
causes problems, we get to solve them the right way this time.
