Douglas Gregor 6fa36b4246 Add -fblocks
llvm-svn: 73804
2009-06-20 00:29:46 +00:00
Douglas Gregor c9c02ed8f4 Keep track of when declarations are "used" according to C and
C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

Eli Friedman 9e81b02ec5 Don't allow defining a block with a non-prototype type. Remove a
hack which introduces some strange inconsistencies in compatibility 
for block pointers.

Note that unlike an earlier revision proposed on cfe-commits, this patch 
still allows declaring block pointers without a prototype.

Eli Friedman 8246b6f889 PR4290: Handle vfprintf in a way that doesn't give any diagnostics for
valid declarations and doesn't give an error for autoconf-style invalid 
redeclarations.  This isn't quite ideal, but I don't see any other way 
easy way to handle it.  (The only thing I can think of that's reasonably 
general is adding a new builtin type FILETy which is only compatible 
with a type equivalent to FILE, and that seems like overkill.)

Eli Friedman fcbf7d2baf PR4287: allow a variadic prototype to make a subsequent K&R style
definition variadic.  I'm not completely sure it's legal, but the 
standard can be interpreted as making it legal, and gcc seems to think 
it's legal, so I didn't add an extension warning.

Chris Lattner 6e127a6d86 Downgrade an error about "return in a no-return function" from being
an error to being a warning that defaults to error.  If you want this to
be a warning, you have to explicitly pass -Winvalid-noreturn to clang to
map it back to a warning.

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 851eb927d7 Fix rdar://6881069, a crash on a form of vector_size that we
don't support.  While it would be nice to support this eventually,
this form is not common at all (just seen in gcc testsuite) and
it might be better to model vector_size as a type attribute anyway.
For now just emit a nice error on it.

Chris Lattner 5b9241b2a6 Fix the atomics sema code to convert operands to the argument types
of the underlying _N builtin, not the the type of the pointee of the
actual type.  This ensures that atomics involving pointers end up
using the correct integer type when they are resolved, avoiding
aborts in codegen.

Chris Lattner dc04654697 reimplement __sync_* builtins to be variadic and to follow the same
semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)

Daniel Dunbar 4dbaaa6f43 Improve handling of (X86) target features.
- This is a WIP...

 - This adds -march= handling to the driver, and fixes the defaulting
   of -mcpu on Darwin (which was using the wrong test).

Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as
 -target-feature [+-]name

In clang-cc, communicate with the (clang) target to discover the legal
features of a target, and the features which are enabled based on
-mcpu. This is currently hardcoded just enough to not be a feature
regression, we need to get this information from the backend's
TableGen information somehow.

This is used to construct the full list of features which are being
used, which is in turn used to initialize the predefines.
