2008-01-19Added FoldingSet style 'profiling' support for APInt.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46188 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-19Made 'FoldingSetNodeID' a proper class instead of a nested class inTed Kremenek
'FoldingSetNodeImpl' (previously 'FoldingSetNodeID' was a typedef of 'FoldingSetNodeImpl::NodeID'). Why? Clients can now easily forward declare 'FoldingSetNodeID' without having to include FoldingSet.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46187 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-19Made 'profiling' of objects in a FoldingSet trait-based using FoldingSetTraitTed Kremenek
instead of always assuming that the stored objects had a method called 'Profile'. The default behavior is to dispatch to a 'Profile' method (as before), but via template specialization this behavior can now be overridden by clients. Added templated class 'FoldingSetNodeWrapper', a generic wrapper class that allows one to insert objects into a FoldingSet that do not directly inherit from FoldingSetNode. This is useful for inserting objects that do not always need to pay the overhead of inheriting from FoldingSetNode, or were designed with that behavior in mind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46186 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-18Fix a latent bug exposed by my truncstore patch. We compiled stfiwx-2.ll to:Chris Lattner
_test: fctiwz f0, f1 stfiwx f0, 0, r4 blr instead of: _test: fctiwz f0, f1 stfd f0, -8(r1) nop nop lwz r2, -4(r1) stb r2, 0(r4) blr The former is not correct (stores 4 bytes, not 1). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46161 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-18Reverted implementation of ImmutableMap::find() to return a TreeTy* instead ofTed Kremenek
an iterator, since the implementation returned an iterator that pointed to a different node! Renamed this implementation to SlimFind() so that users do not expect it to return an iterator (it is a more efficient implementation than returning an iterator if the user just wants to find the value of a key). Added a FIXME to implement ImmutableMap::find() that returns an iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46150 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-17Forward progress: crtbegin.c now compiles successfully!Scott Michel
Fixed CellSPU's A-form (local store) address mode, so that all globals, externals, constant pool and jump table symbols are now wrapped within a SPUISD::AFormAddr pseudo-instruction. This now identifies all local store memory addresses, although it requires a bit of legerdemain during instruction selection to properly select loads to and stores from local store, properly generating "LQA" instructions. Also added mul_ops.ll test harness for exercising integer multiplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46142 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17This commit changes:Chris Lattner
1. Legalize now always promotes truncstore of i1 to i8. 2. Remove patterns and gunk related to truncstore i1 from targets. 3. Rename the StoreXAction stuff to TruncStoreAction in TLI. 4. Make the TLI TruncStoreAction table a 2d table to handle from/to conversions. 5. Mark a wide variety of invalid truncstores as such in various targets, e.g. X86 currently doesn't support truncstore of any of its integer types. 6. Add legalize support for truncstores with invalid value input types. 7. Add a dag combine transform to turn store(truncate) into truncstore when safe. The later allows us to compile CodeGen/X86/storetrunc-fp.ll to: _foo: fldt 20(%esp) fldt 4(%esp) faddp %st(1) movl 36(%esp), %eax fstps (%eax) ret instead of: _foo: subl $4, %esp fldt 24(%esp) fldt 8(%esp) faddp %st(1) fstps (%esp) movl 40(%esp), %eax movss (%esp), %xmm0 movss %xmm0, (%eax) addl $4, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46140 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17new testcase.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46139 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17Implemented "FIXME" in ImutAVLTree: isEqual() now also compares the *data* valueTed Kremenek
and not just the key value when comparing trees. To do this we added data_type and data_type_ref to the ImutContainerInfo trait classes. For values stored in the tree that do not have separate key and data components, data_type is simply a typedef of bool, and isDataEqual() always evaluates to true. This allows us to support both ImmutableSet and ImmutableMap using the same underlying logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46130 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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

2008-01-16My previous commit had an incomplete message, it should have been:Chris Lattner
make the 'fp return in ST(0)' optimization smart enough to look through token factor nodes. THis allows us to compile testcases like CodeGen/X86/fp-stack-retcopy.ll into: _carg: subl $12, %esp call L_foo$stub fstpl (%esp) fldl (%esp) addl $12, %esp ret instead of: _carg: subl $28, %esp call L_foo$stub fstpl 16(%esp) movsd 16(%esp), %xmm0 movsd %xmm0, 8(%esp) fldl 8(%esp) addl $28, %esp ret Still not optimal, but much better and this is a trivial patch.
