Added new types support for load_predicated, store_predicated, halide_xtensa_interleave (for u16 also added Q8 support for native_vector_u16_x3). Improved convert f32 to u32 vectors with proper intrinsic.

similarly, use `std::unordered_set` for the lookups we need. (Note that Halide::Type implicitly converts to halide_type_t at no cost.) * Update mini_webgpu.h --- src/CodeGen_C.h | 2 +- src/CodeGen_Xtensa.cpp | 321 ++++++++++++++++++++++++----------------- src/CodeGen_Xtensa.h | 35 ++++- src/XtensaOptimize.cpp | 82 ----------- src/XtensaOptimize.h | 37 ----- 5 files changed, 225 insertions(+), 252 deletions(-) diff --git a/src/CodeGen_C.h b/src/CodeGen_C.h index a3218bd7587e..24e7559f9ccd 100644 --- a/src/CodeGen_C.h +++ b/src/CodeGen_C.h @@ -86,7 +86,7 @@ class CodeGen_C : public IRPrinter { std::string id;
