2007-10-15Move CreateStackTemporary out to SelectionDAGChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42995 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15One xform performed by LegalizeDAG is transformation of "store of fp" to ↵Chris Lattner
"store of int". Make two changes: 1) only xform "store of f32" if i32 is a legal type for the target. 2) only xform "store of f64" if either i64 or i32 are legal for the target. 3) if i64 isn't legal, manually lower to 2 stores of i32 instead of letting a later pass of legalize do it. This is ugly, but helps future changes I'm about to commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42980 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-14If a target doesn't have HasMULHU or HasUMUL_LOHI, ExpandOp would returnChris Lattner
without lo/hi set. Fall through to making a libcall instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42969 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-13Add a simple optimization to simplify the input toChris Lattner
truncate and truncstore instructions, based on the knowledge that they don't demand the top bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42952 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-12Add support to SplitVectorOp for powi, where the second operandDan Gohman
is a scalar integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42906 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12PPC long double. Implement a couple more conversions.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42888 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-11Codegen support for vector intrinsics.Dan Gohman
Factor out the code that expands the "nasty scalar code" for unrolling vectors into a separate routine, teach it how to handle mixed vector/scalar operands, as seen in powi, and use it for several operators, including sin, cos, powi, and pow. Add support in SplitVectorOp for fpow, fpowi and for several unary operators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42884 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-11Implement ppc long double->uint conversion.Dale Johannesen
Make ppc long double constants print. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42882 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-11Next PPC long double bits. First cut at constants.Dale Johannesen
No compile-time support for constant operations yet, just format transformations. Make readers and writers work. Split constants into 2 doubles in Legalize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42865 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-10Next PPC long double bits: ppcf128->i32 conversion.Dale Johannesen
Surprisingly complicated. Adds getTargetNode for 2 outputs, no inputs (missing). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42822 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-08Migrate X86 and ARM from using X86ISD::{,I}DIV and ARMISD::MULHILO{U,S} toDan Gohman
use ISD::{S,U}DIVREM and ISD::{S,U}MUL_HIO. Move the lowering code associated with these operators into target-independent in LegalizeDAG.cpp and TargetLowering.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42762 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07convertFromInteger, as originally written, expected sign-extendedNeil Booth
input. APInt unfortunately zero-extends signed integers, so Dale modified the function to expect zero-extended input. Make this assumption explicit in the function name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42732 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-06Next powerpc long double bits. Comparisons work,Dale Johannesen
although not well, and shortening FP converts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42672 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-05First round of ppc long double. call/return andDale Johannesen
basic arithmetic works. Rename RTLIB long double functions to distinguish different flavors of long double; the lib functions have different names, alas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42644 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-30Constant fold int-to-long-double conversions;Dale Johannesen
use APFloat for int-to-float/double; use round-to-nearest for these (implementation-defined, seems to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42484 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42359 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-24Use the correct result value type instead of using getValueType(0)Dan Gohman
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort in the included testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42264 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-21Change APFloat::convertFromInteger to take the incomingDale Johannesen
bit width instead of number of words allocated, which makes it actually work for int->APF conversions. Adjust callers. Add const to one of the APInt constructors to prevent surprising match when called with const argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42210 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-14Remove the assumption that FP's are either float orDale Johannesen
double from some of the many places in the optimizers it appears, and do something reasonable with x86 long double. Make APInt::dump() public, remove newline, use it to dump ConstantSDNode's. Allow APFloats in FoldingSet. Expand X86 backend handling of long doubles (conversions to/from int, mostly). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41967 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-12Revise previous patch per review comments.Dale Johannesen
Next round of x87 long double stuff. Getting close now, basically works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41875 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-11Add APInt interfaces to APFloat (allows directlyDale Johannesen
access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41858 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-11Fold the adjust_trampoline intrinsic intoDuncan Sands
init_trampoline. There is now only one trampoline intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41841 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-30Change LegalFPImmediates to use APFloat.Dale Johannesen
Add APFloat interfaces to ConstantFP, SelectionDAG. Fix integer bit in double->APFloat conversion. Convert LegalizeDAG to use APFloat interface in ConstantFPSDNode uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41587 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-09long double 9 of N. This finishes up the X86-32 bitsDale Johannesen
(constants are still not handled). Adds ConvertActions to control fp-to-fp conversions (these are currently defaulted for all other targets, so no changes there). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40958 91177308-0d34-0410-b5e6-96231b3b80d8
