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.

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.

expression is a UDiv and it doesn't appear that the UDiv came from
the user's source.
ScalarEvolution has recently figured out how to compute a tripcount
expression for the inner loop in
SingleSource/Benchmarks/Shootout/sieve.c, using a udiv. Emitting a
udiv instruction dramatically slows down the enclosing loop.

trailing fields may not be represented in initializer lists, they
are being handled as padding and those fields *must* be zero
initialized.

name-lookup ambiguities when there are multiple base classes that are
all specializations of the same class template. This is part of a
general cleanup for ambiguities in template-name lookup. Fixes
PR6717.

time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.
llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2.
Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from
ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

sure to introduce them into the current Scope (when we have one) in
addition to the DeclContext for the class, so that they can be found
by name lookup for inline members of the class. Fixes PR6570.

The information is already available with "opt -analyze". The DominatorTree
does also not have this in its runOnFunction. So they behave now
more consistent.
llvm-svn: 101038
a ScalarEvolution bug with overflow handling is fixed, the normal analysis
code will automatically decline to operate on the icmp instructions which
are responsible for the loop exit.

correctly diagnose instantiation of a function parameter with Objective-C
class type (since Objective-C classes can't be passed by value).
llvm-svn: 101031
function's type is (strictly speaking) non-dependent. This ensures
that, e.g., default function arguments get instantiated properly.
And, since I couldn't resist, collapse the two implementations of
function-parameter instantiation into calls to a single, new function
(Sema::SubstParmVarDecl), since the two had nearly identical code (and
each had bugs the other didn't!). More importantly, factored out the
semantic analysis of a parameter declaration into
Sema::CheckParameter, which is called both by
Sema::ActOnParamDeclarator (when parameters are parsed) and when a
parameter is instantiated. Previously, we were missing some
Objective-C and address-space checks on instantiated function
parameters.
Fixes PR6733.
llvm-svn: 101029
AddRecs so that it checks for overflow in the computation that it is
performing, rather than just checking hasNo{Signed,Unsigned}Wrap, since
those flags are for a different computation. This fixes a bug that
impacts an upcoming change.

instead of deleting just the user. This makes it more consistent with
other code in IndVarSimplify, and theoretically can eliminate more users
earlier.
