The problem is mostly that variadic output instruction
aren't handled, so it is rejected for having an inconsistent
number of operands, and then the right number of operands
isn't emitted.

It appears to ignore or find ambiguous MachineInstrBuilder's conversion
operators that allow conversion to MachineInstr* and
MachineBasicBlock::bundle_iterator.
As a workaround, add an explicit way to get the MachineInstr.

We need to figure out how to track ptrtoint values all the
way until result is converted back to a pointer in order
to correctly rewrite the pointer type.

Every target we support has support for assembly that looks like
a = b - c
.long a
What is special about MachO is that the above combination suppresses the
production of a relocation.
With this change we avoid producing the intermediary labels when they don't
add any value.

The generic code trying to use findCommutedOpIndices won't
understand that it needs to swap the modifier operands also,
so it should fail if they are set.
llvm-svn: 220064
The SelectDS1Addr1Offset complex pattern always tries to store constant
lds pointers in the offset operand and store a zero value in the addr operand.
Since the addr operand does not accept immediates, the zero value
needs to first be copied to a register.
This newly created zero value will not go through normal instruction
selection, so we need to manually insert a V_MOV_B32_e32 in the complex
pattern.
This bug was hidden by the fact that if there was another zero value
in the DAG that had not been selected yet, then the CSE done by the DAG
would use the unselected node for the addr operand rather than the one
that was just created. This would lead to the zero value being selected
and the DAG automatically inserting a V_MOV_B32_e32 instruction.

Currently this only functions to match simple cases
where ds_read2_* / ds_write2_* instructions can be used.
In the future it might match some of the other weird
load patterns, such as direct to LDS loads.
Currently enabled only with a subtarget feature to enable
easier testing.

LLVM assumes INSERT_SUBREG will always have register operands, so
we need to legalize non-register operands, like FrameIndexes, to
avoid random assertion failures.
llvm-svn: 219420
The main reason for this is that the MCAsmInfo class,
which we were previously using as the base class, sets
PrivateGlobalPrefix to "L", which causes all global
functions that start with L to be treated as local symbols.
MCAsmInfoELF sets PrivateGlobalPrefix to ".L", which is what
we want, and it is probably a good idea to use this as the
base class anyway, since we are emitting ELF binaries.

Added a FIXME coment instead, we need to handle the case where the
two DS instructions being compared have different numbers of operands.

No tests for omod since nothing uses it yet, but
this should get rid of the remaining annoying trailing
zeros after some instructions.

Instead of moving the first SGPR that is different than the first,
legalize the operand that requires the fewest moves if one
SGPR is used for multiple operands.
This saves extra moves and is also required for some instructions
which require that the same operand be used for multiple operands.
llvm-svn: 218532
Disable the SGPR usage restriction parts of the DAG legalizeOperands.
It now should only be doing immediate folding until it can be replaced
later. The real legalization work is now done by the other
SIInstrInfo::legalizeOperands

The base implementation of commuteInstruction is used
in some cases, but it turns out this has been broken for a
long time since modifiers were inserted between the real operands.
The base implementation of commuteInstruction also fails on immediates,
which also needs to be fixed.
llvm-svn: 218530
e.g. v_cndmask_b32 requires the condition operand be an SGPR.
If one of the source operands were an SGPR, that would be considered
the one SGPR use and the condition operand would be illegally moved.
