- The idea is that when a match fails, we just try to match each of +'b', +'w',
+'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
it. If all match, we assume it is width generic, and take the 'l' form.
- This would be a horrible hack, if it weren't so simple. Therefore it is an
elegant solution! Chris gets the credit for this particular elegant
solution. :)
- Next step to making this more robust is to have the X86 matcher generate the
mnemonic prefix information. Ideally we would also compute up-front exactly
which mnemonic to attempt to match, but this may require more custom code in
the matcher than is really worth it.

implicitly-defined copy assignment operator, suppress the protected
access check. This eliminates the remaining failure in the
Boost.SmartPtr library (that was a product of the copy-assignment
generation rewrite) and, presumably, the Boost.TR1 library as well.

buildbot: the debugging and non-debugging versions of getFunction were not
functionally equivalent: the non-debugging version wrongly assumed that if a
metadata operand was not metadata, then it had a non-null containing function.
This is not true, since the operand might be a global value, constant etc.

RAUW of a global variable with a local variable in function F,
if function local metadata M in function G was using the global
then M would become function-local to both F and G, which is not
allowed. See the testcase for an example. Fixed by detecting
this situation and zapping the metadata operand when it occurs.

not just the inner expression. This is important if the expression has any
temporaries. Fixes PR 7028.
Basically a symptom of really tragic method names.

update the big red warning at the top. Most of the old content remains
and awaits revision.
Clear out the API changes section, and start it up again with a
mention of the add->fadd transition.

friend function template, be sure to adjust the computed template
argument lists based on the location of the definition of the function
template: it's possible that the definition we're instantiating with
and the template declaration that we found when creating the
specialization are in different contexts, which meant that we would
end up using the wrong template arguments for instantiation.
Fixes PR7013; all Boost.DynamicBitset tests now pass.

to fadd, fsub, and fmul, when used with a floating-point type. LLVM
has supported the new instructions since 2.6, so it's time to get
on board.

debug output is showing machine instructions, the IR-level basic block names
aren't very meaningful, and because multiple machine basic blocks may be
derived from one IR-level BB, they're also not unique.

instructions as the Mac OS X darwin assembler. Some of which like 'fcoml'
assembled to different opcodes. While some of the suffixes were just different.

caused the a pushl instruction to be incorrectly encoding using only two bytes
of immediate, causing the following 2 instruction bytes to be part of the 32-bit
immediate value. Also fixed the one byte form of push to be used when the
immediate would fit in a signed extended byte. Lastly changed the names to not
include the 32 of PUSH32 since they actually push the size of the stack pointer.

Also, pass true for isSigned even when creating constants for unsigned
comparisons, because the point is to create an all-ones constant,
rather than UINT64_MAX, even for integers wider than 64 bits.

mapping from the declaration in the template to the instantiated
declaration before transforming the initializer, in case some crazy
lunatic decides to use a variable in its own initializer. Fixes PR7016.

the DeclContext for the translation unit. This is to workaround a fundamental issue in how
ObjC decls (within an @implementation) are parsed before the ObjCContainerDecl is available.
