| | | | | | | | | | | | | | | | | | the return value is zero-extended if it isn't sign-extended. It may also be any-extended. Also, if a floating point value was returned in a larger floating point type, pass 1 as the second operand to FP_ROUND, which tells it that all the precision is in the original type. I think this is right but I could be wrong. Finally, when doing libcalls, set isZExt on a parameter if it is "unsigned". Currently isSExt is set when signed, and nothing is set otherwise. This should be right for all calls to standard library routines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47122 91177308-0d34-0410-b5e6-96231b3b80d8
* Change how FP immediates are handled. Nate Begeman2008-02-1411-44/+49
| | | | | | | | | | | | | | | 1) ConstantFP is now expand by default 2) ConstantFP is not turned into TargetConstantFP during Legalize if it is legal. This allows ConstantFP to be handled like Constant, allowing for targets that can encode FP immediates as MachineOperands. As a bonus, fix up Itanium FP constants, which now correctly match, and match more constants! Hooray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47121 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach LegalizeTypes how to expand and promote CTLZ,Duncan Sands2008-02-133-18/+108
| | | | | | | | | | | | | | | | | | | 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 Lattner2008-02-131-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
