Evan Cheng f02bb9af8b * 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.

 2005-12-04 08:18:16 +00:00
Evan Cheng e8531381e2 * Added instruction property hasCtrlDep for those which r/w control-flow 
chains.
* Added DAG node property SDNPHasChain for nodes which r/w control-flow
  chains.
* Renamed SDTVT to SDTOther.
* Added several new SDTypeProfiles for BR, BRCOND, RET, and WRITEPORT.
* Added SDNode definitions for BR, BRCOND, RET, and WRITEPORT.

Chris Lattner ecfc7e56c5 Fix test/Regression/ExecutionEngine/2005-12-02-TailCallBug.ll and PR672. 
This also fixes 177.mesa, the only program that fails with --enable-x86-fastcc
turned on.  Given a clean nightly tester run, we should be able to turn it
on by default!

Chris Lattner 0142afd6c1 Don't remove two operand, two result nodes from the binary ops map. These 
should come from the arbitrary ops map.

Chris Lattner ef2d8ca0b6 If a module has a main, but it is defined externally, refuse to run it. 
Attempting to run it will find lli's main, which isn't the desired effect.

Chris Lattner 9d0d715e83 This is a bugfix for SelectNodeTo. In certain situations, we could be 
selecting a node and use a mix of getTargetNode() and SelectNodeTo.  Because
SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert
its result into the CSE maps, we would sometimes miss a CSE opportunity.

This is extremely rare, but worth fixing for completeness.

Evan Cheng d94aa71e1a Use a getCopyToReg() variant to generate a flaggy CopyToReg node. 
llvm-svn: 24558
 2005-12-01 00:41:50 +00:00
Evan Cheng fed83adbe3 Teach tblgen to accept register source operands in patterns, e.g. 
def SHL8rCL  : I<0xD2, MRM4r, (ops R8 :$dst, R8 :$src),
                 "shl{b} {%cl, $dst|$dst, %CL}",
                 [(set R8:$dst, (shl R8:$src, CL))]>, Imp<[CL],[]>;

This generates a CopyToReg operand and added its 2nd result to the shl as
a flag operand.

Nate Begeman cdf2c67888 Stop checking the ValueType of the CodeGenInstruction. Instead, use the 
ValueType from the RegisterClass or Operands.  This step is necessary to
allow RegisterClasses to have multiple ValueTypes.
