2006-03-01- Added VConstant as an abstract version of ConstantVec.Evan Cheng
- All abstrct vector nodes must have # of elements and element type as their first two operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26432 91177308-0d34-0410-b5e6-96231b3b80d8

Patch by Martin Partel! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26313 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBCNate Begeman

2006-01-29Make ConstantFP legalize into TargetConstantFP like other leaf nodes do. AllowChris Lattner
targets to register custom legalizers for ConstantFP in case there isn't a fixed list of constants that can be generated. On some architectures (ia64?) all fp immediates are legal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25769 91177308-0d34-0410-b5e6-96231b3b80d8

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

2005-11-22Check 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
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24306 91177308-0d34-0410-b5e6-96231b3b80d8
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
