Evan Cheng af7de1fba8 The node wrapped in PatLeaf<> should be treated as a leaf even if it isn't 
one, i.e. don't select it.

Evan Cheng 5ece6fa3e0 It should be ok for a xform output type to be different from input type.

Evan Cheng a84bdebfd2 Copy matching pattern's output type info to instruction result pattern. 
The instruction patterns do not contain enough information to resolve the
exact type of the destination if it of a generic vector type.

Evan Cheng c47620b5d8 Temporary hack to enable more (store (op (load ...))) folding. This makes 
it possible when a TokenFactor is between the load and store. But is still
missing some cases due to ordering issue.

Evan Cheng 0fab08eae3 Don't generate silly matching code like this: 
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.

Chris Lattner ecd162d5cd Adjust to new form of handling lexer dependencies, this way shouldn't have 
the problems the old way did.

Evan Cheng 5940bc210e Call InsertISelMapEntry rather than map insertion operator to prevent overly 
aggrssive inlining. This reduces Select_store frame size from 24k to 10k.

llvm-svn: 26095
 2006-02-09 22:12:27 +00:00
Evan Cheng 9ce762d51f Match getTargetNode() changes (now returns SDNode* instead of SDOperand).

Evan Cheng 6dc90ca172 Change Select() from 
SDOperand Select(SDOperand N);
to
void Select(SDOperand &Result, SDOperand N);

llvm-svn: 26067
 2006-02-09 00:37:58 +00:00
Evan Cheng 1630c2848f Hoist all SDOperand declarations within a Select_{opcode}() to the top level 
to reduce stack memory usage. This is intended to work around the gcc bug.

llvm-svn: 26026
 2006-02-07 00:37:41 +00:00
Chris Lattner 5c76b499aa Add support for modifier strings in machine instr descriptions. This allows 
us to avoid creating lots of "Operand" types with different printers, instead
we can fold several together and use modifiers.  For example, we can now use:

${target:call} to say that the operand should be printed like a 'call' operand.

Evan Cheng ebf05bea1b At the end of isel, select a replacement node for each handle that does not 
have one. This can happen if a load's real uses are dead (i.e. they do not
have uses themselves).

llvm-svn: 26014
 2006-02-06 08:12:55 +00:00
Evan Cheng 308d0090e6 Name change.

Evan Cheng aa26555b25 Handle HANDLENODE: just return itself. 
llvm-svn: 26011
 2006-02-05 08:46:14 +00:00
Evan Cheng 368f20e53d Allow more loads to be folded which were previously prevented from happening 
due to ordering issue. i.e. they were selected for chain use first.
Now at load select time, check if it is being selected for a chain use and if
it has only a single real use. If so, return a HANDLENODE (with the load as
its operand) in its place and record it.
When it is folded or the load is selected for a real use, the isel records it
as the replacement for the HANDLENODE. The replacement is done when all nodes
are selected.
This scheme exposed a couple of problems where cycles can happen. (See comments
in EmitMatchCode() for descriptions of the problems and their workaround /
solutions.) These problems have been resolved with a small compile time
penality.

Evan Cheng 7ab4579c68 Re-committing the last bit of change. It shouldn't break PPC this time. 
llvm-svn: 25982
 2006-02-05 05:22:18 +00:00
Chris Lattner 586b06281c Temporarily revert the last change, which breaks PPC and other targets that 
DO select things.

 2006-02-04 09:23:06 +00:00
Evan Cheng ce87cac555 Complex pattern's custom matcher should not call Select() on any operands. 
Select them afterwards if it returns true.
