* Do some cleanups suggested by Chris.David Greene2009-11-121-0/+4
| | | | llvm-svn: 87034
* Make FixedStackPseudoSourceValue a first-class PseudoSourceValue byDavid Greene2009-11-121-23/+2
| | | | | | | | making it visible to clients and adding LLVM-style cast capability. This will be used by AsmPrinter to determine when to emit spill comments for an instruction. llvm-svn: 87019
* Add PseudoSourceValue::mayAlias. It returns true if the object can ever ↵Evan Cheng2009-11-011-0/+17
| | | | | | alias any LLVM IR value. llvm-svn: 85762
* pseudosourcevalue is also still using getGlobalContext(), so it isn'tChris Lattner2009-10-271-0/+1
| | | | | | thread safe either. llvm-svn: 85253
* Remove includes of Support/Compiler.h that are no longer needed after theNick Lewycky2009-10-251-1/+0
| | | | | | VISIBILITY_HIDDEN removal. llvm-svn: 85043
* Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.Nick Lewycky2009-10-251-2/+1
| | | | | | | Chris claims we should never have visibility_hidden inside any .cpp file but that's still not true even after this commit. llvm-svn: 85042
* Spill slots cannot alias.Evan Cheng2009-10-181-4/+7
| | | | llvm-svn: 84432
* -Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixedEvan Cheng2009-10-181-0/+19
| | | | | | | | | | | stack slots and giving them different PseudoSourceValue's did not fix the problem of post-alloc scheduling miscompiling llvm itself. - Apply Dan's conservative workaround by assuming any non fixed stack slots can alias other memory locations. This means a load from spill slot #1 cannot move above a store of spill slot #2. - Enable post-alloc scheduling for x86 at optimization leverl Default and above. llvm-svn: 84424
* Revert 84315 for now. Re-thinking the patch.Evan Cheng2009-10-171-11/+8
| | | | llvm-svn: 84321
* Rename getFixedStack to getStackObject. The stack objects represented are notEvan Cheng2009-10-171-8/+11
| | | | | | necessarily fixed. Only those will negative frame indices are "fixed." llvm-svn: 84315
* Introduce and use convenience methods for getting pointer typesDuncan Sands2009-10-061-1/+1
| | | | | | | where the element is of a basic builtin type. For example, to get an i8* use getInt8PtrTy. llvm-svn: 83379
* Give MachineMemOperand an operator<<, factoring out code fromDan Gohman2009-09-231-7/+3
| | | | | | | | | | | | two different places for printing MachineMemOperands. Drop the virtual from Value::dump and instead give Value a protected virtual hook that can be overridden by subclasses to implement custom printing. This lets printing be more consistent, and simplifies printing of PseudoSourceValue values. llvm-svn: 82599
* Push LLVMContexts through the IntegerType APIs.Owen Anderson2009-08-131-1/+6

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-1/+1
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-1/+2
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Now that errs() is properly non-buffered, there's no need toDan Gohman2009-03-231-1/+1

* Have PseudoSourceValue override Value::dump, so that it worksDan Gohman2008-12-031-0/+4
| | | | | | | on PseudoSourceValue values. This also fixes a FIXME in lib/VMCode/AsmWriter.cpp. llvm-svn: 60507
* Remove the std::ostream form of PseudoSourceValue's print,Dan Gohman2008-08-271-3/+0
| | | | | | which isn't needed anymore. llvm-svn: 55419

* Enable rematerialization of constants using ↵Dan Gohman2008-07-251-0/+20
| | | | | | | | | | AliasAnalysis::pointsToConstantMemory, and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow constants to be rematerialized in PIC mode -- the extra indirection is a complication. llvm-svn: 54000
* Fix edito in the PseudoSourceValue name list.Dan Gohman2008-07-141-1/+1
| | | | llvm-svn: 53562
* Include a frame index in the "fixed stack" pseudo source valueDan Gohman2008-07-111-8/+29
| | | | | | | instead of using the frame index for the SVOffset, which was inconsistent. llvm-svn: 53486
* A quick nm audit turned up several fixed tables and objects that wereDan Gohman2008-03-251-1/+1
| | | | | | | marked read-write. Use const so that they can be allocated in a read-only segment. llvm-svn: 48800
* From Chris' review: fix 80 column violationsDan Gohman2008-02-111-5/+10
| | | | llvm-svn: 46961
* Follow Chris' suggestion; change the PseudoSourceValue accessorsDan Gohman2008-02-071-5/+5
| | | | | | | to return pointers instead of references, since this is always what is needed. llvm-svn: 46857
* Re-apply the memory operand changes, with a fix for the staticDan Gohman2008-02-061-0/+41
