Use the validateTargetOperandClass() hook to match literal '#0' operands in
InstAlias definitions. Previously this required per-instruction C++ munging of the
operand list, but not is handled as a natural part of the matcher. Much better.

No additional tests are required, as the pre-existing tests for these instructions
exercise the new behaviour as being functionally equivalent to the old.

llvm-svn: 174488

For example, ARM has several instructions with a literal '#0' immediate in the syntax
that's not represented as an actual operand. The asm matcher is expected a token
operand, but the parser will have created an immediate operand. This is currently
handled by dedicated per-instruction C++ munging of the ParsedAsmOperand list, but
will be better handled by this hook.

Fix the 'operator==' and 'hasAttributes' queries to take into account

This is useful when parsing an object that references multiple attribute groups.

N.B. If both builders have alignments specified, then they should match!

Failure: undefined symbol 'Lline_table_start0'.
Root-cause: we use a symbol subtraction to calculate at_stmt_list, but
the line table entries are not dumped in the assembly.
Fix: use zero instead of a symbol subtraction for Compile Unit 0.

If an Apple llvmCore build is done without assertions, and a client uses
the llvmCore headers with assertions enabled, or vice versa, then things will
break because some of the structure sizes in the API are different.  Use the
unifdef tool to make the headers unconditionally match the way the llvmCore
libraries were built.

This unit test crashes on Darwon. It needs to be temporarily reverted
to unblock the test infrastructure.

The stuff we're handing are all enums (Attribute::AttrKind), integers and
strings. Don't convert them to Constants, which is an unnecessary step here. The
rest of the changes are mostly mechanical.

is a vararg function.

The original code was examining flag OutputArg::IsFixed to determine whether
CC_MipsN_VarArg or CC_MipsN should be called. This is not correct, since this
flag is often set to false when the function being analyzed is a non-variadic
function.

Reapply r174343, with a fix for a scary DAG combine bug where it failed to differentiate between the alignment of the
base point of a load, and the overall alignment of the load.  This caused infinite loops in DAG combine with the
original application of this patch.

ORIGINAL COMMIT LOG:
When the target-independent DAGCombiner inferred a higher alignment for a load,
it would replace the load with one with the higher alignment.  However, it did
not place the new load in the worklist, which prevented later DAG combines in
the same phase (for example, target-specific combines) from ever seeing it.

This patch corrects that oversight, and updates some tests whose output changed
due to slightly different DAGCombine outputs.

All targets are now adding return value registers as implicit uses on
return instructions, and there is no longer a need for the live out
lists.

llvm-svn: 174417

Now that return value registers are return instruction uses, there is no
need for special treatment of return blocks.
