Instructions that are inserted in a basic block can still be decorated
with addOperand(MO).

Make the two-argument addOperand() function contain the actual
implementation. This function will now always have a valid MF reference
that it can use for memory allocation.

llvm-svn: 170798

This function is often used to decorate dangling instructions, so a
context reference is required to allocate memory for the operands.

Also add a corresponding MachineInstrBuilder method.

This is supposed to be a mechanical change with no functional effects.

InstrEmitter can generate all types of MachineOperands which revealed
that MachineInstrBuilder was missing a few methods, added by this patch.

Besides providing a context pointer to MI::addOperand(),
MachineInstrBuilder seems like a better fit for this code.

llvm-svn: 170712

This automatically passes a context pointer to MI->addOperand().

No testcase because it is apparently not so trivial to construct.

Use the version that also takes an MF reference instead.

It would technically be possible to extract an MF reference from the MI
as MI->getParent()->getParent(), but that would not work for MIs that
are not inserted into any basic block.

Given the reasonably small number of places this constructor was used at
all, I preferred the compile time check to a run time assertion.

bitwidth op back to the original size. If we reduce ANDs then this can cause
an endless loop. This patch changes the ZEXT to ANY_EXTEND if the demanded bits
are equal or smaller than the size of the reduced operation.

Rename the 'Attributes' class to 'Attribute'. It's going to represent a single attribute in the future.

Teach SimplifySetCC that comparing AssertZext i1 against a constant 1 can be rewritten as a compare against a constant 0 with the opposite condition.

The bundle_iterator::operator++ function now doesn't need to dig out the
basic block and check against end(). It can use the isBundledWithSucc()
flag to find the last bundled instruction safely.

Similarly, MachineInstr::isBundled() no longer needs to look at
iterators etc. It only has to look at flags.

llvm-svn: 170473

Now that the bundle flag aware APIs are all in place, it is possible to
continuously verify the flag consistency.

llvm-svn: 170465

The new bidirectional bundle flags are redundant, so inadvertent bundle
tearing can be detected in the machine code verifier.

llvm-svn: 170463

The bundle-related MI flags need to be kept in sync with the neighboring
instructions. Don't allow the bulk flag-setting setFlags() function to
change them.

Also don't copy MI flags when cloning an instruction. The clone's bundle
flags will be set when it is explicitly inserted into a bundle.

llvm-svn: 170459

Remove the instr_iterator versions of the splice() functions. It doesn't
seem useful to be able to splice sequences of instructions that don't
consist of full bundles.

The normal splice functions that take MBB::iterator arguments are not
changed, and they can move whole bundles around without any problems.
