2006-02-23Fix an endianness problem on big-endian targets with expanded operandsChris Lattner
to inline asms. Mark some methods const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26334 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-22Don't return registers from register classes that aren't legal.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26317 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-22Change a whole bunch of code to be built around RegsForValue instead ofChris Lattner
a single register number. This fully implements promotion for inline asms, expand is close but not quite right yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26316 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-20Fix a problem Nate and Duraid reported where simplifying nodes can causeChris Lattner
them to get ressurected, in which case, deleting the undead nodes is unfriendly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26291 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-20Fix a problem on itanium with memset. The value to set has been promoted toChris Lattner
i64 before this code, so zero_ext doesn't work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26290 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-18Add a fold for add that exchanges it with a constant shift if possible, soNate Begeman
that the shift may be more easily folded into other operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26286 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-18Add checks to make sure we don't create bogus extend nodes, and fix a bugNate Begeman
where we were doing exactly that which was causing failures on x86 and alpha. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26284 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17Fix a tricky issue in the SimplifyDemandedBits code where CombineTo wasn'tChris Lattner
exactly the API we wanted to call into. This fixes the crash on crafty last night. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26269 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-17Don't expand sdiv by power of two before legalize, since it will likelyNate Begeman
generate illegal nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26261 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBCNate Begeman
and SUBE nodes that actually expose what's going on and allow for significant simplifications in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26255 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17Fix another miscompilation exposed by lencode, where we lowered i64->f32Chris Lattner
conversions to __floatdidf instead of __floatdisf on targets that support f32 but not i64 (e.g. sparc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26254 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-16Dumb bug. Code sees a memcpy from X+c so it increments src offset. But itEvan Cheng
turns out not to point to a constant string but it forgot change the offset back. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26242 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-16Rework the SelectionDAG-based implementations of SimplifyDemandedBitsNate Begeman
and ComputeMaskedBits to match the new improved versions in instcombine. Tested against all of multisource/benchmarks on ppc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26238 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-16If the false case is the current basic block, then this is a self loop.Evan Cheng
We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra instruction in the loop. Instead, invert the condition and emit "Loop: ... br!cond Loop; br Out. Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26231 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-14now that libcalls don't suck, we can remove this hackChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26164 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-14Fix a latent bug in the call sequence handling stuff. Some targets (e.g. x86)Chris Lattner
create these nodes with flag results. Remember that we legalized them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26156 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-13Rename to better reflect usage (current and planned.)Jim Laskey
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26145 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-13Completely rewrite libcall insertion by the legalizer, providing theChris Lattner
following handy-dandy properties: 1. it is always correct now 2. it is much faster than before 3. it is easier to understand This implementation builds off of the recent simplifications of the legalizer that made it single-pass instead of iterative. This fixes JM/lencod, JM/ldecod, and CodeGen/Generic/2006-02-12-InsertLibcall.ll (at least on PPC). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26144 91177308-0d34-0410-b5e6-96231b3b80d8

to SelIDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26115 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-09Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gccEvan Cheng
problem where it inline the map insertion call too aggressively. Before this change it was producing a frame size of 24k for Select_store(), now it's down to 10k (by calling this method rather than calling the map insertion operator). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26094 91177308-0d34-0410-b5e6-96231b3b80d8
