2006-04-17Prefer to allocate V2-V5 before V0,V1. This lets us generate code like this:Chris Lattner
vspltisw v2, -12 vrlw v2, v2, v2 instead of: vspltisw v0, -12 vrlw v2, v0, v0 when a function is returning a value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27771 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-17Pull some code out into a helper function.Chris Lattner
Effeciently codegen even splats in the range [-32,30]. This allows us to codegen <30,30,30,30> as: vspltisw v0, 15 vadduwm v2, v0, v0 instead of as a cp load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27750 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-16Implement a TODO: have the legalizer canonicalize a bunch of operations toChris Lattner
one type (v4i32) so that we don't have to write patterns for each type, and so that more CSE opportunities are exposed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27731 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-12Add a new way to match vector constants, which make it easier to bang bits ofChris Lattner
different types. Codegen spltw(0x7FFFFFFF) and spltw(0x80000000) without a constant pool load, implementing PowerPC/vec_constants.ll:test1. This compiles: typedef float vf __attribute__ ((vector_size (16))); typedef int vi __attribute__ ((vector_size (16))); void test(vi *P1, vi *P2, vf *P3) { *P1 &= (vi){0x80000000,0x80000000,0x80000000,0x80000000}; *P2 &= (vi){0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF}; *P3 = vec_abs((vector float)*P3); } to: _test: mfspr r2, 256 oris r6, r2, 49152 mtspr 256, r6 vspltisw v0, -1 vslw v0, v0, v0 lvx v1, 0, r3 vand v1, v1, v0 stvx v1, 0, r3 lvx v1, 0, r4 vandc v1, v1, v0 stvx v1, 0, r4 lvx v1, 0, r5 vandc v0, v1, v0 stvx v0, 0, r5 mtspr 256, r2 blr instead of (with two constant pool entries): _test: mfspr r2, 256 oris r6, r2, 49152 mtspr 256, r6 li r6, lo16(LCPI1_0) lis r7, ha16(LCPI1_0) li r8, lo16(LCPI1_1) lis r9, ha16(LCPI1_1) lvx v0, r7, r6 lvx v1, 0, r3 vand v0, v1, v0 stvx v0, 0, r3 lvx v0, r9, r8 lvx v1, 0, r4 vand v1, v1, v0 stvx v1, 0, r4 lvx v1, 0, r5 vand v0, v1, v0 stvx v0, 0, r5 mtspr 256, r2 blr GCC produces (with 2 cp entries): _test: mfspr r0,256 stw r0,-4(r1) oris r0,r0,0xc00c mtspr 256,r0 lis r2,ha16(LC0) lis r9,ha16(LC1) la r2,lo16(LC0)(r2) lvx v0,0,r3 lvx v1,0,r5 la r9,lo16(LC1)(r9) lwz r12,-4(r1) lvx v12,0,r2 lvx v13,0,r9 vand v0,v0,v12 stvx v0,0,r3 vspltisw v0,-1 vslw v12,v0,v0 vandc v1,v1,v12 stvx v1,0,r5 lvx v0,0,r4 vand v0,v0,v13 stvx v0,0,r4 mtspr 256,r12 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27624 91177308-0d34-0410-b5e6-96231b3b80d8
2006-04-12Rename get_VSPLI_elt -> get_VSPLTI_eltChris Lattner
Canonicalize BUILD_VECTOR's that match VSPLTI's into a single type for each form, eliminating a bunch of Pat patterns in the .td file and allowing us to CSE stuff more aggressively.
