* Don't mark scalar integer multiplication as Expand on x86, since x86Dan Gohman2008-02-181-0/+8
| | | | | | | | | | | | | | has plain one-result scalar integer multiplication instructions. This avoids expanding such instructions into MUL_LOHI sequences that must be special-cased at isel time, and avoids the problem with that code that provented memory operands from being folded. This fixes PR1874, addressesing the most common case. The uncommon cases of optimizing multiply-high operations will require work in DAGCombiner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47277 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach LegalizeTypes how to expand and promote CTLZ,Duncan Sands2008-02-131-12/+11
| | | | | | | | | | | | | | | | | | | CTTZ and CTPOP. The expansion code differs from that in LegalizeDAG in that it chooses to take the CTLZ/CTTZ count from the Hi/Lo part depending on whether the Hi/Lo value is zero, not on whether CTLZ/CTTZ of Hi/Lo returned 32 (or whatever the width of the type is) for it. I made this change because the optimizers may well know that Hi/Lo is zero and exploit it. The promotion code for CTTZ also differs from that in LegalizeDAG: it uses an "or" to get the right result when the original value is zero, rather than using a compare and select. This also means the value doesn't need to be zero extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47075 91177308-0d34-0410-b5e6-96231b3b80d8
* In SDISel, for targets that support FORMAL_ARGUMENTS nodes, lower thisChris Lattner2008-02-131-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | node as soon as we create it in SDISel. Previously we would lower it in legalize. The problem with this is that it only exposes the argument loads implied by FORMAL_ARGUMENTs after legalize, so that only dag combine 2 can hack on them. This causes us to miss some optimizations because datatype expansion also happens here. Exposing the loads early allows us to do optimizations on them. For example we now compile arg-cast.ll to: _foo: movl $2147483647, %eax andl 8(%esp), %eax ret where we previously produced: _foo: subl $12, %esp movsd 16(%esp), %xmm0 movsd %xmm0, (%esp) movl $2147483647, %eax andl 4(%esp), %eax addl $12, %esp ret It might also make sense to do this for ISD::CALL nodes, which have implicit stores on many targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47054 91177308-0d34-0410-b5e6-96231b3b80d8

This improves code somewhat because we now avoid using reg+reg addressing when it can be avoided. It also simplifies the address selection logic, which was the main point for doing this. Also, for various global variables that would be loaded using SPU's A-form addressing, prefer D-form offs[reg] addressing, keeping the base in a register if the variable is used more than once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46483 91177308-0d34-0410-b5e6-96231b3b80d8
