2010-03-04Fix memcheck-found leaks: one false positive from using new[], and one trueJeffrey Yasskin
positive where pointers would be leaked on llvm_shutdown. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97759 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87034 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-12Make FixedStackPseudoSourceValue a first-class PseudoSourceValue byDavid Greene
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87019 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-01Add PseudoSourceValue::mayAlias. It returns true if the object can ever ↵Evan Cheng
alias any LLVM IR value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85762 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27pseudosourcevalue is also still using getGlobalContext(), so it isn'tChris Lattner
thread safe either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85253 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-25Remove includes of Support/Compiler.h that are no longer needed after theNick Lewycky
VISIBILITY_HIDDEN removal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85043 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-25Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.Nick Lewycky
Chris claims we should never have visibility_hidden inside any .cpp file but that's still not true even after this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85042 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-18Spill slots cannot alias.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84432 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-18-Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixedEvan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Revert 84315 for now. Re-thinking the patch.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84321 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Rename getFixedStack to getStackObject. The stack objects represented are notEvan Cheng
necessarily fixed. Only those will negative frame indices are "fixed." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84315 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Introduce and use convenience methods for getting pointer typesDuncan Sands
where the element is of a basic builtin type. For example, to get an i8* use getInt8PtrTy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-23Give MachineMemOperand an operator<<, factoring out code fromDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82599 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Push LLVMContexts through the IntegerType APIs.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78948 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
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"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-23Now that errs() is properly non-buffered, there's no need toDan Gohman
explicitly flush it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67526 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Have PseudoSourceValue override Value::dump, so that it worksDan Gohman
on PseudoSourceValue values. This also fixes a FIXME in lib/VMCode/AsmWriter.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60507 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Remove the std::ostream form of PseudoSourceValue's print,Dan Gohman
which isn't needed anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55419 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-24simplify PseudoSourceValue printing a bit. Unnest all of ↵Chris Lattner
PseudoSourceValue.cpp from the llvm namespace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55293 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-24Print PseudoSourceValue.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55291 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-25Enable rematerialization of constants using ↵Dan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54000 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14Fix edito in the PseudoSourceValue name list.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53562 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-11Include a frame index in the "fixed stack" pseudo source valueDan Gohman
instead of using the frame index for the SVOffset, which was inconsistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53486 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-25A quick nm audit turned up several fixed tables and objects that wereDan Gohman
marked read-write. Use const so that they can be allocated in a read-only segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48800 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-11From Chris' review: fix 80 column violationsDan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46961 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Follow Chris' suggestion; change the PseudoSourceValue accessorsDan Gohman
to return pointers instead of references, since this is always what is needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46857 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-06Re-apply the memory operand changes, with a fix for the staticDan Gohman
initializer problem, a minor tweak to the way the DAGISelEmitter finds load/store nodes, and a renaming of the new PseudoSourceValue objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46827 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-31Revert 46556 and 46585. Dan please fix the PseudoSourceValue problem and ↵Evan Cheng
re-commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46623 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30Add a new PseudoSourceValue class, which will be used to help trackDan Gohman
memory reference information in the backend. Most of this was written by Florian Brander, cleanup and updating to TOT by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46556 91177308-0d34-0410-b5e6-96231b3b80d8
