2002-05-22Move debug options out of header files so that the header does not haveChris Lattner
to #include CommandLine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2712 91177308-0d34-0410-b5e6-96231b3b80d8

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
2002-04-09Clean up the ownership model a bit so that nodes actually get deleted moreChris Lattner
frequently. This still leaks edges quite a bit, but it leaks no nodes (I think). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2190 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-07Change references to the Method class to be references to the FunctionChris Lattner
class. The Method class is obsolete (renamed) and all references to it are being converted over to Function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2144 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-24Use deterministic iterator for SchedGraphs. This is actually notVikram S. Adve
useful right now when we only do local scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1975 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

2002-02-05Minor change: Methods that return ValueSet's that are guaranteed to be validChris Lattner
return references instead of pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1719 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

2001-11-12Eliminate most uses of the machine instruction vector for each LLVM instr,Vikram S. Adve
since some m. instr. may be generated by LLVM instrs. in other blocks. Handle non-SSA (anti and output) edges and true edges uniformly by working with machine instructions alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1269 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
2001-11-11Only add true dep. edges from an earlier to a later instruction.Vikram S. Adve
This wasn't a problem until we started putting copies for Phi values that produced cycles in the SchedGraph! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1254 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
2001-11-08Major change to how defs are found when adding dependences (theyVikram S. Adve
are now found as part of the initial walk of the machine code). Also memory load/store instructions can be generated for non-memory LLVM instructions, which wasn't handled before. It is now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1199 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
2001-11-05Modified graph construction to use one pass to find all defs.Vikram S. Adve
Avoids having to handle some special cases that cause complex interactions with instr. selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1138 91177308-0d34-0410-b5e6-96231b3b80d8
2001-10-28Allow combinations of True/Anti/Output flags for each edge toVikram S. Adve
support, e.g., dependences on Call instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1009 91177308-0d34-0410-b5e6-96231b3b80d8
2001-10-28Add edges between call instructions and (a) load/store instructions, andVikram S. Adve
(b) any instructions that use or set CC registers. Whether or not the latter are needed really should be machine-dependent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1008 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
2001-10-17Separate VM instruction that generates the instructions that compute a valueVikram S. Adve
from the value itself (the one causing an edge) because the latter may be a temporary used within the instruction sequence for the VM instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@858 91177308-0d34-0410-b5e6-96231b3b80d8
