If store's chain operand is load, then use load's chain operand instead. If
it isn't (likely a TokenFactor), then do not allow the folding.

Another folding problem: if a node r/w chain or flag, don't fold it if it
...
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.

instruction to produce a result. e.g MUL8m, the instruction does not

Added field noResults to Instruction.
...
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

This ugly patch works around a GCC bug where it is compiling SelectCode to
...
use too much stack space, overflowing the stack for large functions. Instead
of emitting new SDOperands in each match block, we emit some common ones at
the top of SelectCode then reuse them when possible.
This reduces the stack size of SelectCode from 28K to 21K. Note that GCC
compiles it to 512 bytes :-/
I've filed GCC PR 25505 to track this.

Added a break that I meant to include originally, for efficiency. Basically
...
it keeps it from trying to add the same node to the node set
over and over if it matches multiple given patterns. Also in cases where there
are a lot of patterns to be matched, and it matches an early one, this
will make the script run slightly faster. It's more there because it logically
should be, than anything else, I mean, Python is never going to be fast ;-)

This is a script to extract nodes and edges associated with those nodes
...
from a dot file that is the output of DSA. Nodes to extract
are specified by giving the name of the node seen in the graphical
representation, i.e. in the .ps if the node is specified %xyz
asking for just x, xy, or xyz will retain it in the output file.
Because it operates on substrings underspecifying may result
in additional unexpected nodes. Be as specific as possible.
Obviously, however, if you ask for %xyz and there is a
getelementptr of %xyz you will get both nodes. Some manual
editing may still be necessary because of this, but this script
can pare down 10,000 line files to 20 line files, making like easier.

At top of generated isel SelectCode() is this:
...
if (!N.Val->hasOneUse()) {
std::map<SDOperand, SDOperand>::iterator CGMI = CodeGenMap.find(N);
if (CGMI != CodeGenMap.end()) return CGMI->second;
}
Suppose a DAG like this:
X
^ ^
/ \
USE1 USE2
Suppose USE1 is being selected first and during which X is selected and
returned a new node. After this, USE1 is no longer an use of X. During USE2
selection, X will be selected again since it has only one use!
The fix is to always query CodeGenMap.

* Commit the fix (by Chris) for a tblgen type inferencing bug.
...
* Enhanced tblgen to handle instructions which have chain operand and writes a
chain result.
* Enhanced tblgen to handle instructions which produces no results. Part of
the change is a temporary hack which relies on instruction property (e.g.
isReturn, isBranch). The proper fix would be to change the .td syntax to
separate results dag from ops dag.

Implement a couple of new (important) features.
...
1. If an operation has to be int or fp and the target only supports one
int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
for patterns involving those operators, since we do not emit the code to
check for them yet. This prevents PPC from generating FP ops currently.
Also move some code around into more logical places.

Currently we check that immediate values live on the RHS of commutative

def ORI : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
"ori $dst, $src1, $src2",
[(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;
results in:
