2009-01-29Correct the algorithms for choosing spill and restore points so that we ↵Owen Anderson
don't try to insert loads/stores between call frame setup and the actual call. This fixes the last known failure for the pre-alloc-splitter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63339 91177308-0d34-0410-b5e6-96231b3b80d8

basic blocks have live-ins. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63323 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29In the case of an extractelement on an insertelement value,Dan Gohman
the element indices may be equal if either one is not a constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Revert r63273. This was already implemented by Dale. There's no need for myBill Wendling
change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63301 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Fix an issue where restores could be inserted after a terminator instruction,Owen Anderson
and an iterator invalidation issue. FreeBench/pifft no longer miscompiles with these fixes! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63293 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29Add support for aggressive load-use-store folding. This takes care of the Owen Anderson
vast majority of code size regressions introduced by pre-alloc-splitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63274 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29- Add DebugLoc to getTargetNode(). Bill Wendling
- Modify TableGen to add the DebugLoc when calling getTargetNode. (The light-weight wrappers are only temporary. The non-DebugLoc version will be removed once the whole debug info stuff is finished with.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63273 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63267 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Make x86's BT instruction matching more thorough, and add someDan Gohman
dagcombines that help it match in several more cases. Add several more cases to test/CodeGen/X86/bt.ll. This doesn't yet include matching for BT with an immediate operand, it just covers more register+register cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63266 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29A slight compile time optimization. If the caller knows there isn't a free ↵Evan Cheng

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63245 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Add DebugLoc-aware constructors for SDNode derivedDale Johannesen
classes (those that reasonably have a DebugLoc associated with them). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63236 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63233 91177308-0d34-0410-b5e6-96231b3b80d8

after the others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63227 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Fixed extract element when the result needs to be promoted and the input ↵Mon P Wang
widened. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63217 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Make isOperationLegal do what its name suggests, and introduce aDan Gohman
new isOperationLegalOrCustom, which does what isOperationLegal previously did. Update a bunch of callers to use isOperationLegalOrCustom instead of isOperationLegal. In some case it wasn't obvious which behavior is desired; when in doubt I changed then to isOperationLegalOrCustom as that preserves their previous behavior. This is for the second half of PR3376. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63212 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63198 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Fix PR3415 (infinite loop in EscapeAnalysis) byDuncan Sands
deleting the escape analysis pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63197 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28The memory alignment requirement on some of the mov{h|l}p{d|s} patterns are ↵Evan Cheng
16-byte. That is overly strict. These instructions read / write f64 memory locations without alignment requirement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63195 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63171 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Use ValueType::bitsLT to simplify some code.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63170 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Use ZERO_EXTEND instead of ANY_EXTEND when promotingDan Gohman
shift amounts, to avoid implicitly assuming that target architectures will ignore the high bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63169 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63161 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Add type DIE into appropriate context DIE.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63154 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Add a DebugLoc field and some simple accessors.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63152 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Treat [1 x i8] zeroinitializer as a C string, placing such stuff intoAnton Korobeynikov
mergeable string section. I don't see any bad impact of such decision (rather then placing it into mergeable const section, as it was before), but at least Darwin linker won't complain anymore. The problem in LLVM is that we don't have special type for string constants (like gcc does). Even more, we have two separate types: ConstatArray for non-null strings and ConstantAggregateZero for null stuff.... It's a bit weird :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63142 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63132 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Add an assertion to the form of SelectionDAG::getConstant that takesDan Gohman
a uint64_t to verify that the value is in range for the given type, to help catch accidental overflow. Fix a few places that relied on getConstant implicitly truncating the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63128 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63120 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63119 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Simplify findNonImmUse; return the result using the return valueDan Gohman
instead of via a by-reference argument. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63118 91177308-0d34-0410-b5e6-96231b3b80d8
