f45d323 Andrew Adams 04 May 2021, 16:32:56 UTC Non-widening lowering of rounding shifts (#5956) This version lowers it without needing to widen, which is a large win on x86 for 16 and 32-bit types (3.8x faster and 2.8x faster respectively). It's a very slight slowdown for 8-bit because x86 doesn't have 8-bit shift instructions. Also drive-by typo fix. 04 May 2021, 16:32:56 UTC

1b3cbcb aankit-ca 26 April 2021, 17:55:12 UTC [Hexagon] Try vdelta/vrdelta before vlut for some shuffles. (#5935) The patch tries to generate vdelta/vrdelta instructions for non-ramp shuffles. Eg: shuffle(lut_expr, < 0, 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24, 25, 27, 28, 29, 30, 31, 32, 33, 34, 36, 37, 38, 39, 40, 41, 42, 43, 45, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, 70>) can be generated using vrdelta. The patch also fixes a bug where we bitcast vdelta/vrdelta with 16/32 bits elements to wrong type. User would see the below error: llvm-project/llvm/lib/IR/Instructions.cpp:2905: static llvm::CastInst *llvm::CastInst::Create(Instruction::CastOps, llvm::Value *, llvm::Type *, const llvm::Twine &, llvm::Instruction *): Assertion `castIsValid(op, S, Ty) && "Invalid cast!"' failed.

42092e3 Zalman Stern 01 April 2021, 19:13:01 UTC Fix an issue in Halide's float16 compilation support. Add tests. (#5872) In EmulateFloat16Math.cpp, conversion from 32-bit float to 16-bit float could produce a NaN value when and infinity is correct. This is because for numbers larger than the exact infinity value, the mantissa could be non zero. Add tests to cover this case, and float16 infinities in general. Couple small style/comment cleanups. 01 April 2021, 19:13:01 UTC
cb78a6b Steven Johnson 31 March 2021, 22:30:55 UTC Don't strip strict_float() from lets (#5871) * Don't strip strict_float() from lets Bug injected in #5856: the change in Simplify_Let.cpp was inadvertently stripping `strict_float()` calls that wrapped the RHS of a Let-expr, which can change results nontrivially in some cases. I don't think a new test for this fix is practical -- it would be a little fragile, as it would rely on the specifics of simplification that could change over time. As a drive-by, also added an explicit rule to Simplify_Call to ensure that strict_float(strict_float(x)) -> strict_float(x) in *all* cases. (The existing rule didn't do this in all cases.) 31 March 2021, 22:30:55 UTC

f2143bf Steven Johnson 30 March 2021, 19:29:32 UTC Add a way to set a GeneratorInput's type in code (#5868) * Add a way to set a GeneratorInput's type in code Currently, if you want to vary the type of a Generator's inputs or outputs, you have to specify the types in the makefile. This can be awkward for things with complex logic. This PR proposes adding a way to do this: a new `set_type()` method which can only be called from the rarely-used Generator::configure() method. It only allows setting the type for an input or output that has no type specified. I'm not 100% sure if this is a good idea, but for certain rare corner cases, it may be quite handy. (Note that extending this to allow specifying dimensions and/or array size in the same way might be handy, but is omitted from this PR.) * Update Generator.h * Also add set_dimensions, set_array_size 30 March 2021, 19:29:32 UTC
2dd7a6b Thales Sabino 30 March 2021, 19:00:21 UTC Add support for AVX-512 VNNI saturating dot products (#5807) * Add support for AVX-512 VNNI saturating dot products This commit adds support to Intel VNNI saturating dot product instructions vpdpbuds and vpdpwssd This was accomplished by adding a new VectorReduce operation to perform the saturating_add and exposing a new inline reduction saturaring_sum. Users can then write RDom r(0, 4); f(x) = saturating_sum(i32(0), i16(i8(g(x + r)) * u8(h(x + r)))) bool override_associativity_test = true; int vector_width = 4; Var xo, xi; f.update() .split(x, xo, xi, vector_width) .atomic(override_associativity_test) .vectorize(r) .vectorize(xi); To lower the expression into a call to vpdpbuds. Note that override_associativity_test is set to true or halide will fail to prove the associativity of the saturating_add operation Add support for VectorReduce::SaturatingAdd in CodeGen_LLVM Code is correctly generated when no intrinsic is available to perform a saturating dot product. Add vpdpbusds,vpdpwssd tests to simd_op_check Test if the saturating dot product instructions are being generated for AVX512_SapphireRapids targets * Improve code according to report from clang-tidy * Make init_val a const ref since it only used that way inside saturating_sum * clang-format * Revert removal of clang-format tag in CodeGen_X86.cpp * Add SaturatingAdd case Monotonic VectorReduce visit * Bail out in Bounds when dealing with a SaturatingAdd VectorReduce * Move saturating_mul to Simplify_Internal.h so it can be used in Simplify_Exprs.cpp * Remove init_val from the saturating_sum inline reduction * Unconditionally override the associativity test in the simd_op_check tests * Remove annonymous namespace from saturating_mul utility Co-authored-by: Thales Sabino <thales@codeplay.com> 30 March 2021, 19:00:21 UTC
