Don't dump the function! git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_22@46699 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17When a live virtual register is being clobbered by an implicit def, it is ↵Evan Cheng
spilled and the spill is its kill. However, if the local allocator has determined the register has not been modified (possible when its value was reloaded), it would not issue a restore. In that case, mark the last use of the virtual register as kill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46111 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17Replace std::vector<bool> with BitVector.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46104 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Fixes a nasty dag combiner bug that causes a bunch of tests to fail at -O0.Evan Cheng
It's not safe to use the two value CombineTo variant to combine away a dead load. e.g. v1, chain2 = load chain1, loc v2, chain3 = load chain2, loc v3 = add v2, c Now we replace use of v1 with undef, use of chain2 with chain1. ReplaceAllUsesWith() will iterate through uses of the first load and update operands: v1, chain2 = load chain1, loc v2, chain3 = load chain1, loc v3 = add v2, c Now the second load is the same as the first load, SelectionDAG cse will ensure the use of second load is replaced with the first load. v1, chain2 = load chain1, loc v3 = add v1, c Then v1 is replaced with undef and bad things happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46099 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Do not mark EH tables no-dead-strip unless theDale Johannesen
associated function is so marked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46088 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Fix a ppc long double regression I introduced yesterday due to aChris Lattner
simplification. This fixes automotive-basicmath on PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46072 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16merge a few pieces of code that do the store/load to stack Chris Lattner
pattern to use EmitStackConvert now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46066 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16rename ExpandBIT_CONVERT to EmitStackConvert, generalizing Chris Lattner
it to allow it to emit different load and store kinds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46065 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16simplify a bunch of code by using SelectionDAG::CreateStackTemporary Chris Lattner
instead of inlining its body. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46062 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Change legalizeop of FP_ROUND and FP_EXTEND to not fall throughChris Lattner
into the ANY_EXTEND/ZERO_EXTEND/SIGN_EXTEND code to simplify it. Unmerge the code for FP_ROUND and FP_EXTEND from each other to make each one simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46061 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Factor the ReachesChainWithoutSideEffects out of dag combiner into Chris Lattner
a public SDOperand::reachesChainWithoutSideEffects method. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46050 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Fix and enable EH for x86-64 Darwin. AddsDale Johannesen
ShortenEHDataFor64Bits as a not-very-accurate abstraction to cover all the changes in DwarfWriter. Some cosmetic changes to Darwin assembly code for gcc testsuite compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46029 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Move some calls to getVRegDef higher in the callgraph, so they don't get ↵Owen Anderson
executed as frequently in performance sensitive code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46027 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15The type of the 'abort' node should be pointer type (becauseChris Lattner
it's a function pointer) not MVT::Other. This fixes builtin_trap lowering on ppc, alpha, ia64 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46018 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Remove DefInst from LiveVariables::VarInfo. Use the facilities on ↵Owen Anderson
MachineRegisterInfo instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46016 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Add support for targets that have a legal ISD::TRAP.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46014 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Oops. Forgot to commit this.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46002 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15For PR1839: add initial support for __builtin_trap. llvm-gcc part is missedAnton Korobeynikov
as well as PPC codegen git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46001 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15ByVal stack slot alignment should be at least as large as pointer ABI alignment.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45995 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14don't create the post-ra scheduler unless it is enabled.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45972 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14remove dead #includeChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45971 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-13Remove the assumption that byval has been applied toDuncan Sands
a pointer to a struct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45939 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-12implement support for sinking a load out the bottom of a block thatChris Lattner
has no stores between the load and the end of block. This works great and sinks hundreds of stores, but we can't turn it on because machineinstrs don't have volatility information and we don't want to sink volatile stores :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45894 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Simplify the side effect stuff a bit more and make licm/sinkingChris Lattner
both work right according to the new flags. This removes the TII::isReallySideEffectFree predicate, and adds TII::isInvariantLoad. It removes NeverHasSideEffects+MayHaveSideEffects and adds UnmodeledSideEffects as machine instr flags. Now the clients can decide everything they need. I think isRematerializable can be implemented in terms of the flags we have now, though I will let others tackle that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45843 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Clamp down on sinking of lots of instructions.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45841 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Output sinl for a long double FSIN node, not sin.Duncan Sands
Likewise fix up a bunch of other libcalls. While there I remove NEG_F32 and NEG_F64 since they are not used anywhere. This fixes 9 Ada ACATS failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45833 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-10Emit unused EH frames for weak definitions on Darwin,Dale Johannesen
because assembler/linker can't cope with weak absolutes. PR 1880. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45811 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Get rid of all uses of LiveVariables::VarInfo::DefInst in favor of the ↵Owen Anderson
equivalent API from MachineRegisterInfo. Once all clients are switched over, the former will be going away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45805 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Add more comments explaining the basics of how the decision of when to ↵Owen Anderson
rename and when to insert copies is made. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45799 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Get rid of the isKillInst predicate. LiveVariables already provides this ↵Owen Anderson
information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45797 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Copies need to be inserted before the first terminator, not at the end of ↵Owen Anderson
the block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45791 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-09Clean up StrongPHIElimination a bit, and add some more comments to the ↵Owen Anderson
internal structures. There's still more work to do on this front. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45783 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-08Make load->store deletion a bit smarter. This allows us to compile this:Chris Lattner
void test(long long *P) { *P ^= 1; } into just: _test: movl 4(%esp), %eax xorl $1, (%eax) ret instead of code like this: _test: movl 4(%esp), %ecx xorl $1, (%ecx) movl 4(%ecx), %edx movl %edx, 4(%ecx) ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45762 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner
Make MachineInstr::getDesc return a reference instead of a pointer, since it can never be null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45695 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07Rename all the M_* flags to be namespace qualified enums, and switch Chris Lattner
all clients over to using predicates instead of these flags directly. These are now private values which are only to be used to statically initialize the tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45692 91177308-0d34-0410-b5e6-96231b3b80d8
