Add dag combiner code to recognize rotl, rotr Add ppc code to match rotl Targets should add rotl/rotr patterns if they have them git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25222 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-11Fix calls that need to store values in stack slots, to not copy the stackChris Lattner
pointer. This allows us to emit stuff like this: li r10, 0 stw r10, 56(r1) or r3, r10, r10 or r4, r10, r10 or r5, r10, r10 or r6, r10, r10 or r7, r10, r10 or r8, r10, r10 or r9, r10, r10 bl L_bar$stub instead of this: or r2, r1, r1 ;; Extraneous copy. li r10, 0 stw r10, 56(r2) or r3, r10, r10 or r4, r10, r10 or r5, r10, r10 or r6, r10, r10 or r7, r10, r10 or r8, r10, r10 or r9, r10, r10 bl L_bar$stub wowness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25221 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-11Dead FP arguments still use an incoming FP reg. This fixesChris Lattner
Regression/CodeGen/PowerPC/2006-01-11-darwin-fp-argument.ll, which was distilled from a miscompilation in 252.eon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25217 91177308-0d34-0410-b5e6-96231b3b80d8

constant offsets from statics into the address arithmetic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24999 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-10Add support for TargetConstantPool nodes to the dag isel emitter, and useNate Begeman
them in the PPC backend, to simplify some logic out of Select and SelectAddr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24657 91177308-0d34-0410-b5e6-96231b3b80d8
2005-12-06Use new PPC-specific nodes to represent shifts which require the 6-bitChris Lattner
amount handling that PPC provides. These are generated by the lowering code and prevents the dag combiner from assuming (rightfully) that the shifts don't only look at 5 bits. This fixes a miscompilation of crafty with the new front-end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24615 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-17add an option to generate completely non-pic code, corresponding to whatChris Lattner
gcc -static produces on PPC. This is used for building kexts and other things. With this, materializing the address of a global looks like: lis r2, ha16(L_H$non_lazy_ptr) la r3, lo16(L_H$non_lazy_ptr)(r2) we're still emitting stubs for functions, which is wrong. That is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24399 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-17Fix a bug that resistor on IRC hit where we tried to create token factorChris Lattner
nodes of load results, not of their chain results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24398 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-17Enable global address legalization, fixing a todo and allowing the removalChris Lattner
of some code. This exposes the implicit load from the stubs to the DAG, allowing them to be optimized by the dag combiner. It also moves darwin specific stuff out of the isel into the legalizer, and allows more to be moved to the .td file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24397 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-17Use the right accessor to create this nodeChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24394 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-17Add an initial hack at legalizing GlobalAddress into the appropriate nodesChris Lattner
on Darwin to remove smarts from the isel. This is currently disabled by default (uncomment setOperationAction(ISD::GlobalAddress to enable it). tblgen needs to become smarter about tglobaladdr nodes and bigger patterns needed to be added to the .td file. However, we can currently emit stuff like this: :) li r2, lo16(L_x$non_lazy_ptr) lis r3, ha16(L_x$non_lazy_ptr) lwzx r2, r3, r2 The obvious improvements will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24390 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-17When lowering direct calls, lower them to use a targetglobaladress directlyChris Lattner
instead of a globaladdress. This has no effect on the generated code at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24386 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-25Correctly Expand or Promote FP_TO_UINT based on the capabilities of theNate Begeman
machine. This allows us to generate great code for i32 FP_TO_UINT now on targets with 64 bit extensions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23993 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23986 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-21Invert the TargetLowering flag that controls divide by consant expansion.Nate Begeman
Add a new flag to TargetLowering indicating if the target has really cheap signed division by powers of two, make ppc use it. This will probably go away in the future. Implement some more ISD::SDIV folds in the dag combiner Remove now dead code in the x86 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23853 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-20Move the target constant divide optimization up into the dag combiner, soNate Begeman
that the nodes can be folded with other nodes, and we can not duplicate code in every backend. Alpha will probably want this too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23835 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-18Add the ability to lower return instructions to TargetLowering. ThisNate Begeman
allows us to lower legal return types to something else, to meet ABI requirements (such as that i64 be returned in two i32 regs on Darwin/ppc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23802 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-18Do the right thing and enable 64 bit regs under the control of a subtargetNate Begeman
option. Currently the only way to enable this is to specify the 64bitregs mattr flag. It is never enabled by default on any config yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23779 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-18First bits of 64 bit PowerPC stuff, currently disabled. A lot of this isNate Begeman
purely mechanical. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23778 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-16More PPC32 -> PPC changes, as well as merging some classes that wereNate Begeman
redundant after the change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23759 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-14Rename PPC32*.h to PPC*.hChris Lattner
This completes the grand PPC file renaming git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23745 91177308-0d34-0410-b5e6-96231b3b80d8
