2005-12-06Teach the SelectionDAG ISel how to turn ConstantPacked values intoNate Begeman
constant nodes with vector types. Also teach the asm printer how to print ConstantPacked constant pool entries. This allows us to generate altivec code such as the following, which adds a vector constantto a packed float. LCPI1_0: <4 x float> < float 0.0e+0, float 0.0e+0, float 0.0e+0, float 1.0e+0 > .space 4 .space 4 .space 4 .long 1065353216 ; float 1 .text .align 4 .globl _foo _foo: lis r2, ha16(LCPI1_0) la r2, lo16(LCPI1_0)(r2) li r4, 0 lvx v0, r4, r2 lvx v1, r4, r3 vaddfp v0, v1, v0 stvx v0, r4, r3 blr For the llvm code: void %foo(<4 x float> * %a) { entry: %tmp1 = load <4 x float> * %a; %tmp2 = add <4 x float> %tmp1, < float 0.0, float 0.0, float 0.0, float 1.0 > store <4 x float> %tmp2, <4 x float> *%a ret void } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24616 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-29Add support for a new STRING and LOCATION node for line number support, patchChris Lattner
contributed by Daniel Berlin, with a few cleanups here and there by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24512 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-22Check in code to scalarize arbitrarily wide packed types for some simpleNate Begeman
vector operations (load, add, sub, mul). This allows us to codegen: void %foo(<4 x float> * %a) { entry: %tmp1 = load <4 x float> * %a; %tmp2 = add <4 x float> %tmp1, %tmp1 store <4 x float> %tmp2, <4 x float> *%a ret void } on ppc as: _foo: lfs f0, 12(r3) lfs f1, 8(r3) lfs f2, 4(r3) lfs f3, 0(r3) fadds f0, f0, f0 fadds f1, f1, f1 fadds f2, f2, f2 fadds f3, f3, f3 stfs f0, 12(r3) stfs f1, 8(r3) stfs f2, 4(r3) stfs f3, 0(r3) blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24484 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-19Teach LLVM how to scalarize packed types. Currently, this only works onNate Begeman
packed types with an element count of 1, although more generic support is coming. This allows LLVM to turn the following code: void %foo(<1 x float> * %a) { entry: %tmp1 = load <1 x float> * %a; %tmp2 = add <1 x float> %tmp1, %tmp1 store <1 x float> %tmp2, <1 x float> *%a ret void } Into: _foo: lfs f0, 0(r3) fadds f0, f0, f0 stfs f0, 0(r3) blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24416 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-11added a chain outputAndrew Lenharth

2005-11-11Add support for a cycle counter intrinsic. As basically all processors haveAndrew Lenharth
this and have it in about the same form, I think this makes sense. on X86, you do a RDTSC (64bit result, from any ring since the P5MMX) on Alpha, you do a RDCC on PPC, there is a sequence which may or may not work depending on how things are setup by the OS. Or something like that. Maybe someone who knows PPC can add support. Something about the time base register. on Sparc, you read %tick, which in some solaris versions (>=8) is readable by userspace on IA64 read ar.itc So I think the ulong is justified since all of those are 64bit. Support is slighly flaky on old chips (P5 and lower) and sometimes depends on OS (PPC, Sparc). But for modern OS/Hardware (aka this decade), we should be ok. I am still not sure what to do about lowering. I can either see a lower to 0, to gettimeofday (or the target os equivalent), or loudly complaining and refusing to continue. I am commiting an Alpha implementation. I will add the X86 implementation if I have to (I have use of it in the near future), but if someone who knows that backend (and the funky multi-register results) better wants to add it, it would take them a lot less time ;) TODO: better lowering and legalizing, and support more platforms git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24299 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-09Switch the allnodes list from a vector of pointers to an ilist of nodes.Chris Lattner
This eliminates the vector, allows constant time removal of a node from a graph, and makes iteration over the all nodes list stable when adding nodes to the graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24262 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-08Change the ValueList array for each node to be shared instead of individuallyChris Lattner
allocated. Further, in the common case where a node has a single value, just reference an element from a small array. This is a small compile-time wi. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24250 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-08Switch the operandlist/valuelist from being vectors to being just an array.Chris Lattner
This saves 12 bytes from SDNode, but doesn't speed things up substantially (our graphs apparently already fit within the cache on my g5). In any case this reduces memory usage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24248 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26Change ConstantPoolSDNode to actually hold the Constant itself instead ofChris Lattner
putting it into the constant pool. This allows the isel machinery to create constants that it will end up deciding are not needed, without them ending up in the resultant function constant pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23081 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-17Add two new methods isTargetOpcode() which returns true if the node typeNate Begeman
is greater than the range of building selection dag node types, and getTargetOpcode(), which returns the node opcode less the value of isd::builtin_op_end, which specifies the end of the builtin types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22844 91177308-0d34-0410-b5e6-96231b3b80d8

subjected to folding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22812 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-16Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef)Chris Lattner
used to tack a register number onto the node. Instead of doing this, make a new node, RegisterSDNode, which is a leaf containing a register number. These three operations just become normal DAG nodes now, instead of requiring special handling. Note that with this change, it is no longer correct to make illegal CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this is bad, so don't do it. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22806 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-16Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nastyNate Begeman
fixme from the PowerPC backend. Emit slightly better code for legalizing select_cc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22805 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-10Add new node, SELECT_CC. This node is for targets that don't nativelyNate Begeman
implement SELECT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22755 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-09Eliminate the SetCCSDNode in favor of a CondCodeSDNode class. This pulls theChris Lattner
CC out of the SetCC operation, making SETCC a standard ternary operation and CC's a standard DAG leaf. This will make it possible for other node to use CC's as operands in the future... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22728 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-10Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.Chris Lattner

2005-07-10Introduce a new VTSDNode class with the ultimate goal of eliminating theChris Lattner
MVTSDNode class. This class is used to provide an operand to operators that require an extra type. We start by converting FP_ROUND_INREG and SIGN_EXTEND_INREG over to using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22364 91177308-0d34-0410-b5e6-96231b3b80d8
