for reference binding. The code attempted to handle both the
computation of the ICS and the actual conversion, but the latter is an
anachronism: we now use InitializationSequence for that.
Sema::CheckReferenceInit is now a static function TryReferenceInit
that's only use within overload resolution, and has been simplified
slightly. It still needs to be updated per C++ [over.ics.ref], by
eliminating more of the lvalue/rvalue checks.

We have some code in llvm and clang where a BumpPtrAllocator is declared in a
class but never used in the common case. Stop wasting memory there.

recognize all the valid rotated immediates. This fixes the disassembler
issue and will also help codegen for some unusual constant values.

numerator is an induction variable. For example, with code like this:
for (i=0;i<n;++i)
x[i%n] = 0;
IndVarSimplify will now recognize that i is always less than n inside
the loop, and eliminate the remainder.

from a conversion function template specialization to one of exact
match rank. We only know how to test this in C++0x with default
function template arguments, but it's also in the C++03 spec. Fixes
PR6285.

copying the type location information from the conversion-type-id into
the type location information for the function type. Do something
similar for constructors and destructors, by giving their "void"
return type source-location information.
In all of these cases, we previously left this type-source information
uninitialized, which led to various unfortunate crashes.
We still aren't tracking good source-location information for the
actual names. That's PR6357.
John, please check my sanity on this.

in an input file like this:
# 42
int x;
we were emitting:
# <something>
int x;
(with a space before the int) because we weren't clearing the leading
whitespace flag properly after the \n from the directive was handled.

If we have this situation:
jCC L1
jmp L2
L1:
...
L2:
...
We can get a small performance boost by emitting this instead:
jnCC L2
L1:
...
L2:
...
This testcase shows an example of this:
float func(float x, float y) {
double product = (double)x * y;
if (product == 0.0)
return product;
return product - 1.0;
}

libEnhancedDisassembly, so we now build the
static library in all cases (although the shared
library is only built when requested/possible).
Also, fixed a bug where edis wasn't properly
initializing the targets it uses.
llvm-svn: 101072
actually turned it on. If a diag is produced by a warning which
is an extension but defaults to on, and has no warning group, don't
print any option info.
