Jakob Stoklund Olesen 4843178d6b Teach the machine code verifier to use getSubRegisterRegClass(). 
The old approach was wrong. It had an off-by-one error.

Anders Carlsson be48c548c5 Correctly initialize bases with member pointers. This should fix PR6441 but that test case is a bit weird and I'd like to investigate further before closing that bug.

Douglas Gregor 86ad085b40 Give a slight edge to the context-sensitive keyword 'super' over 
non-function-local declarations with names similar to what the user
typed. For example, this allows us to correct 'supper' to 'super' in
an Objective-C message send, even though the C function 'isupper' has
the same edit distance.

Douglas Gregor 5fd04d4832 Tweak typo-correction logic a bit regarding "super", so that we 
consider "super" as a candidate whenever we're parsing an expression
within an Objective-C method in an interface that has a superclass. At
some point, we'd like to give "super" a little edge over non-local
names; that will come later.

Douglas Gregor b92ea59481 I hate this commit. 
Revert much of the implementation of C++98/03 [temp.friend]p5 in
r103943 and its follow-ons r103948 and r103952. While our
implementation was technically correct, other compilers don't seem to
implement this paragraph (which forces the instantiation of friend
functions defined in a class template when a class template
specialization is instantiated), and doing so broke a bunch of Boost
libraries. 

Since this behavior has changed in C++0x (which instantiates the
friend function definitions when they are used), we're going to skip
the nowhere-implemented C++98/03 semantics and go straight to the
C++0x semantics.

This commit is a band-aid to get Boost up and running again. It
doesn't really fix PR6952 (which this commit un-fixes), but it does
deal with the way Boost.Units abuses this particular paragraph.

 2010-05-18 05:22:06 +00:00
Anders Carlsson af9e5afe54 Start laying out bases as individual fields. We still use ugly i8 arrays but this is a step in the right direction.

John McCall d3dfbd6f4f If a switch condition is constant, don't warn about missing enum cases. 
If a switch condition is constant, warn if there's no case for it.

Constant switch conditions do come up in reasonable template code.

a temporary with a noreturn destructor has been created. Fixes PR6884 for now.

Douglas Gregor 96cdb1590e Instantiate attributes on typedefs. This is a quick fix for PR7148, 
when we really need a proper audit of our handling of attributes in
templates.

Jakob Stoklund Olesen 93d8844699 ARMBaseRegisterInfo::estimateRSStackSizeLimit() could return prematurely with a 
too large limit.

The function would return immediately when finding an addrmode 3/5 instruction.
It needs to keep scanning in case there is an addrmode 6 instruction which drops
the limit to 0.

A test case is very difficult to produce because it will only fail when the
scavenger is used.

Daniel Dunbar ce5e1bb326 MC: Add dyn_cast support to MCSection. 
- Of questionable utility, since in general anything which wants to do this should probably be within a target specific hook, which can rely on the sections being of the appropriate type. However, it can be useful for short term hacks.
