2002-04-29Add new optional getPassName() virtual function that a Pass can overrideChris Lattner
to make debugging output a lot nicer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2395 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-27* Rename MethodPass class to FunctionPassChris Lattner
- Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-09No need to reserve space, erasing does not change the size of the container.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2201 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-09* Add a file header with some informationChris Lattner
* Delete the DelaySlotInfo objects created by the SchedulingManager class. These leaked objects were accounting for 3/4 of the memory leaked by the backend, so this is a relatively major win. * Reorganize SchedulingManager::getDelaySlotInfoForInstr so that it has better code locality (making it easier to read). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2197 91177308-0d34-0410-b5e6-96231b3b80d8

2002-03-24Add option to disable scheduling.Vikram S. Adve
Destroy live-variable information after scheduling so it is recomputed before later phases (e.g., reg. allocation). Use deterministic iterator to enumerate sched graphs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1972 91177308-0d34-0410-b5e6-96231b3b80d8
2002-02-24* Silence signed/unsigned warningsChris Lattner
* Make it compile with GCC 3.0.4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1787 91177308-0d34-0410-b5e6-96231b3b80d8
2002-02-12* Pull BasicBlock::pred_* and BasicBlock::succ_* out of BasicBlock.h and intoChris Lattner
llvm/Support/CFG.h * Make pred & succ iterators for intervals global functions * Add #includes that are now neccesary because BasicBlock.h doesn't include InstrTypes.h anymore git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1750 91177308-0d34-0410-b5e6-96231b3b80d8
2002-02-05* Eliminate the LiveVarSet class, making applyTranferFuncForMInst a staticChris Lattner
function in the one .cpp file that uses it. Use ValueSet's instead. * Prepare to delete LiveVarSet.h & LiveVarSet.cpp * Eliminate the ValueSet class, making all old member functions into global templates that will eventually be moved to Support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1711 91177308-0d34-0410-b5e6-96231b3b80d8
2002-02-04* The itf exposed by InstrScheduling is now a single function to create the ↵Chris Lattner
right pass * InstructionScheduling is now a real pass * InstrSched _uses_ LiveVar analysis, instead of creating it's own copy many times through a loop. In this was LiveVarAnalysis is actually even SHARED by Register allocation. * SchedPriorities is now passed the live var information in git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1700 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1503 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-27Create a new #include "Support/..." directory structure to move thingsChris Lattner
from "llvm/Support/..." that are not llvm dependant. Move files and fix #includes git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1400 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-12Major improvement to how nodes are built for a BB.Vikram S. Adve
LLVM instruction is no longer recorded in each node, but BB is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1262 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-09Use node->getOpCode() instead of node->getMachineInstr()->getOpCode().Vikram S. Adve
Much nicer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1223 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-08MachineCodeForMethod is now an annotation on class Method.Vikram S. Adve
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1198 91177308-0d34-0410-b5e6-96231b3b80d8
2001-10-22Modify code that processes delay slots so that it preserves anyVikram S. Adve
useful instructions already inserted into delay slots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@945 91177308-0d34-0410-b5e6-96231b3b80d8
2001-10-10Don't insert useful instructions in delay slot of a RETURN.Vikram S. Adve
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@721 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-30Bug fixes:Vikram S. Adve
(1) Ensure that delay slot instructions are not moved out of place (this was happening for some CALL instructions). Basically, we need to move all delay slot instructions out of the graph and handle them along with the delayed control transfer instruction. (2) Mark scheduled instructions correctly when instructions are scheduled in more than one cycle in a single step (due to delay slots). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@678 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-18Add new entry/exit edges when removing delay slot nodes from the graph.Vikram S. Adve
Renamed some header files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@610 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-14Chris seems fond of #include <vector>. Fix these. Also convert use list inChris Lattner
Value to a vector instead of a list. Move SchedGraph.h & SchedPriorities.h into lib/CodeGen/InstrScheduling git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@572 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-14Split Target/Machine.h into three files:Chris Lattner
* Machine.h * InstInfo.h * SchedInfo.h TODO: Split out reg info stuff git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@567 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-14Make a new llvm/Target #include directory.Chris Lattner
Move files from lib/CodeGen/TargetMachine to lib/Target Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h} Prepare to split TargetMachine.h into several smaller files git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@566 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-14Checkin changes to:Chris Lattner
1. Clean up the TargetMachine structure. No more wierd pointers that have to be cast around and taken care of by the target. 2. Instruction Scheduling now takes the schedinfo as an argument. The same should be done with the instinfo, it just isn't now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@565 91177308-0d34-0410-b5e6-96231b3b80d8
2001-09-09I really don't like it when people break the build.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@510 91177308-0d34-0410-b5e6-96231b3b80d8

2001-08-28Implementation of instruction scheduling for LLVM.Vikram S. Adve
Currently schedules one basic block at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@396 91177308-0d34-0410-b5e6-96231b3b80d8
