* MEGAPATCH checkin.Chris Lattner2002-06-251-16/+13
| | | | | | | For details, See: docs/2002-06-25-MegaPatchInfo.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2778 91177308-0d34-0410-b5e6-96231b3b80d8
* Add new optional getPassName() virtual function that a Pass can overrideChris Lattner2002-04-291-0/+9
| | | | | | | to make debugging output a lot nicer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2395 91177308-0d34-0410-b5e6-96231b3b80d8
* * Rename MethodPass class to FunctionPassChris Lattner2002-04-271-7/+7
| | | | | | | | | | | | | | | | - 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
* Don't pad spills and temp. stack areas for alignment.Vikram S. Adve2002-04-251-4/+5
| | | | | | | | Freeze auto vars and spill areas when their sizes are used for computing other offsets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2317 91177308-0d34-0410-b5e6-96231b3b80d8
* * Add a useful file commentChris Lattner2002-04-091-91/+7
| | | | | | | | | * Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp -> Among other things, this eliminates the need for the minstrVec static global array. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2195 91177308-0d34-0410-b5e6-96231b3b80d8

* Change references to the Method class to be references to the FunctionChris Lattner2002-04-071-37/+39
| | | | | | | | 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 The Method class is obsolete (renamed) and all references to it are being converted over to Function.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

| | | | | | | | | | 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

* Convert RegisterAllocator interface to opaque pass type, so that users do notChris Lattner2002-02-041-1/+1
| | | | | | | need to know _anything_ about RegAlloc to use it. Well in the end maybe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1681 91177308-0d34-0410-b5e6-96231b3b80d8
* * Minor cleanupsChris Lattner2002-02-041-0/+1
| | | | | | | | | | | * Reduce number of #includes * Remove blatently misleading qualifiers (how do you have an inlined pure virtual function?) * Remove unnecesary & ignored qualifiers (const int argument vs int argument) * SparcInternals.h now no longer #includes RegClass.h or SparcRegClassInfo.h * Pull inlined functions out of .h file if they are virtual and interfere with dependencies git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1677 91177308-0d34-0410-b5e6-96231b3b80d8

* Split RegisterAllocation stuff OUT of Sparc.cpp into a well defined passChris Lattner2002-02-041-27/+2
| | | | | | | that has a very minimal interface (like it should have). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1667 91177308-0d34-0410-b5e6-96231b3b80d8
* Move a ton of tables out of SparcInternals.h and move them to Sparc.cpp.Chris Lattner2002-02-041-0/+685
| | | | | | | | Eventually they will probably get moved again, but at least now they aren't having to be compiled by 7 different .cpp files... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1666 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | 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
