2006-04-06Support pattern matching vsldoi(x,y) and vsldoi(x,x), which allows the f.e. toChris Lattner
lower it and LLVM to have one fewer intrinsic. This implements CodeGen/PowerPC/vec_shuffle.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27450 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-04Fix some broken logic that would cause us to codegen ↵Chris Lattner
{2147483647,2147483647,2147483647,2147483647} as 'vspltisb v0, -1'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27413 91177308-0d34-0410-b5e6-96231b3b80d8
2006-04-04Ask legalize to promote all vector shuffles to be v16i8 instead of having toChris Lattner
handle all 4 PPC vector types. This simplifies the matching code and allows us to eliminate a bunch of patterns. This also adds cases we were missing, such as CodeGen/PowerPC/vec_splat.ll:splat_h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27400 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-31Implement an item from the readme, folding vcmp/vcmp. instructions withChris Lattner
identical instructions into a single instruction. For example, for: void test(vector float *x, vector float *y, int *P) { int v = vec_any_out(*x, *y); *x = (vector float)vec_cmpb(*x, *y); *P = v; } we now generate: _test: mfspr r2, 256 oris r6, r2, 49152 mtspr 256, r6 lvx v0, 0, r4 lvx v1, 0, r3 vcmpbfp. v0, v1, v0 mfcr r4, 2 stvx v0, 0, r3 rlwinm r3, r4, 27, 31, 31 xori r3, r3, 1 stw r3, 0(r5) mtspr 256, r2 blr instead of: _test: mfspr r2, 256 oris r6, r2, 57344 mtspr 256, r6 lvx v0, 0, r4 lvx v1, 0, r3 vcmpbfp. v2, v1, v0 mfcr r4, 2 *** vcmpbfp v0, v1, v0 rlwinm r4, r4, 27, 31, 31 stvx v0, 0, r3 xori r3, r4, 1 stw r3, 0(r5) mtspr 256, r2 blr Testcase here: CodeGen/PowerPC/vcmp-fold.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27290 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-28Use normal lvx for scalar_to_vector instead of lve*x. They do the exactChris Lattner
same thing and we have a dag node for the former. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27205 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-28Tblgen doesn't like multiple SDNode<> definitions that map to the sameenum ↵Chris Lattner
value. Split them into separate enums. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27201 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-27SelectionDAGISel can now natively handle Switch instructions, in the sameNate Begeman
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary search tree of basic blocks. The new approach has several advantages: it is faster, it generates significantly smaller code in many cases, and it paves the way for implementing dense switch tables as a jump table by handling switches directly in the instruction selector. This functionality is currently only enabled on x86, but should be safe for every target. In anticipation of making it the default, the cfg is now properly updated in the x86, ppc, and sparc select lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27156 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-25Codegen things like:Chris Lattner
<int -1, int -1, int -1, int -1> and <int 65537, int 65537, int 65537, int 65537> Using things like: vspltisb v0, -1 and: vspltish v0, 1 instead of using constant pool loads. This implements CodeGen/PowerPC/vec_splat.ll:splat_imm_i{32|16}. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27106 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-24Disable the i32->float G5 optimization. It is unsafe, as documented in theChris Lattner

2006-03-22When possible, custom lower 32-bit SINT_TO_FP to this:Chris Lattner
_foo2: extsw r2, r3 std r2, -8(r1) lfd f0, -8(r1) fcfid f0, f0 frsp f1, f0 blr instead of this: _foo2: lis r2, ha16(LCPI2_0) lis r4, 17200 xoris r3, r3, 32768 stw r3, -4(r1) stw r4, -8(r1) lfs f0, lo16(LCPI2_0)(r2) lfd f1, -8(r1) fsub f0, f1, f0 frsp f1, f0 blr This speeds up Misc/pi from 2.44s->2.09s with LLC and from 3.01->2.18s with llcbeta (16.7% and 38.1% respectively). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26943 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-20Add support for generating vspltw, instead of a vperm instruction with aChris Lattner
constant pool load. This generates significantly nicer code for splats. When tblgen gets bugfixed, we can remove the custom selection code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26898 91177308-0d34-0410-b5e6-96231b3b80d8
