The later API is nicer than the former, and is correct regarding wrap-around offsets (if anyone cares).
There are a few more places left with duplicated code, which I'll remove soon.

directly.

This is in preparation for removing the use of the 'Attribute' class as a
collection of attributes. That will shift to the AttributeSet class instead.

llvm-svn: 171253

Refactor DAGCombinerInfo. Change the different booleans that indicate if we are before or after different runs of DAGCo, with the CombineLevel enum.
Also, added a new API for checking if we are running before or after the LegalizeVectorOps phase.

per compile unit/skeleton compile unit. Update tests accordingly.

These are now generally used for all diagnostics from the backend, not just
for inline assembly, so this drops the "InlineAsm" from the names.  No
functional change.  (I've left aliases for the old names but only for long
enough to let me switch over clang to use the new ones.)

llvm-svn: 171047

When the backend is used from clang, it should produce proper diagnostics
instead of just printing messages to errs(). Other clients may also want to
register their own error handlers with the LLVMContext, and the same handler
should work for warnings in the same way as the existing emitError methods.

Back when this exception was added, it was skipping a lot more code, but
now it just looks like a premature optimization.

The representation of the Operands array is going to change soon so it
can be allocated from a BumpPtrAllocator.

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.

llvm-svn: 170797

llvm-svn: 170796

llvm-svn: 170771

into the DwarfUnits class.

llvm-svn: 170770

llvm-svn: 170766

llvm-svn: 170716

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.

Accordingly, add MVT::getVT.

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.

llvm-svn: 170505

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