* New DAG node properties SNDPInFlag, SNDPOutFlag, and SNDPOptInFlag to replaceEvan Cheng2006-01-091-2/+0
| | | | | | hasInFlag, hasOutFlag. llvm-svn: 25155
* Added field noResults to Instruction.Evan Cheng2005-12-261-0/+1
| | | | | | | | | | | | 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. llvm-svn: 25017
* * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.Evan Cheng2005-12-231-0/+2
| | | | | | | | * Added a pseudo instruction (for each target) that represent "return void". This is a workaround for lack of optional flag operand (return void is not lowered so it does not have a flag operand.) llvm-svn: 24997
* Added support to specify predicates.Evan Cheng2005-12-141-0/+14
| | | | llvm-svn: 24715
* * Added instruction property hasCtrlDep for those which r/w control-flowEvan Cheng2005-12-041-0/+1
| | | | | | | | | | | 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. llvm-svn: 24586

| | | | | | work. This change has no effect on generated code. llvm-svn: 24563
* Add the majority of the vector machien value types we expect to support,Nate Begeman2005-11-291-1/+7
