Fix PR3522. It's not safe to sink into landing pad BB's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64790 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-17Merge 64314 from mainline.Tanya Lattner
Make a transformation added in 63266 a bit less aggressive. It was transforming (x&y)==y to (x&y)!=0 in the case where y is variable and known to have at most one bit set (e.g. z&1). This is not correct; the expressions are not equivalent when y==0. I believe this patch salvages what can be salvaged, including all the cases in bt.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64782 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04Disable support for vicmp/vfcmp from the LLVM 2.5 release branch, like we ↵Tanya Lattner
did for LLVM 2.4. These are slated to be removed (PR3370) and we don't want to have to be backwards compatible with them in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@63788 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03rearrange how SRoA handles promotion of allocas to vectors.Chris Lattner
With the new world order, it can handle cases where the first store into the alloca is an element of the vector, instead of requiring the first analyzed store to have the vector type itself. This allows us to un-xfail test/CodeGen/X86/vec_ins_extract.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63590 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-01Fix PR3453 and probably a bunch of other potentialDuncan Sands
crashes or wrong code with codegen of large integers: eliminate the legacy getIntegerVTBitMask and getIntegerVTSignBit methods, which returned their value as a uint64_t, so couldn't handle huge types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63494 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-31Fix PR3401: when using large integers, the typeDuncan Sands
returned by getShiftAmountTy may be too small to hold shift values (it is an i8 on x86-32). Before and during type legalization, use a large but legal type for shift amounts: getPointerTy; afterwards use getShiftAmountTy, fixing up any shift amounts with a big type during operation legalization. Thanks to Dan for writing the original patch (which I shamelessly pillaged). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63482 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26Fix PR3393, which amounts to a bug in the expensiveDuncan Sands
checking logic. Rather than make the checking more complicated, I've tweaked some logic to make things conform to how the checking thought things ought to be, since this results in a simpler "mental model". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63048 91177308-0d34-0410-b5e6-96231b3b80d8

- Rename fcmp.ll test to fcmp32.ll, start adding new double tests to fcmp64.ll - Fix select_bits.ll test - Capitulate to the DAGCombiner and move i64 constant loads to instruction selection (SPUISelDAGtoDAG.cpp). <rant>DAGCombiner will insert all kinds of 64-bit optimizations after operation legalization occurs and now we have to do most of the work that instruction selection should be doing twice (once to determine if v2i64 build_vector can be handled by SelectCode(), which then runs all of the predicates a second time to select the necessary instructions.)

2009-01-25Teach 2addr pass to be do more commuting. If both uses of a two-address ↵Evan Cheng
instruction are killed, but the first operand has a use before and after the def, commute if the second operand does not suffer from the same issue. %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1028 %reg1030<def> = ADD8rr %reg1028<kill>, %reg1029<kill>, %EFLAGS<imp-def,dead> In this case, it might not be possible to coalesce the second MOV8rr instruction if the first one is coalesced. So it would be profitable to commute it: %reg1028<def> = EXTRACT_SUBREG %reg1027<kill>, 1 %reg1029<def> = MOV8rr %reg1028 %reg1029<def> = SHR8ri %reg1029, 7, %EFLAGS<imp-def,dead> insert => %reg1030<def> = MOV8rr %reg1029 %reg1030<def> = ADD8rr %reg1029<kill>, %reg1028<kill>, %EFLAGS<imp-def,dead> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62954 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-22Don't create ISD::FNEG nodes after legalize if they aren't legal.Dan Gohman
Simplify x+0 to x in unsafe-fp-math mode. This avoids a bunch of redundant work in many cases, because in unsafe-fp-math mode, ISD::FADD with a constant is considered free to negate, so the DAGCombiner often negates x+0 to -0-x thinking it's free, when in reality the end result is -x, which is more expensive than x. Also, combine x*0 to 0. This fixes PR3374. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62789 91177308-0d34-0410-b5e6-96231b3b80d8
