* Refactor instance_traits_util and add unit tests tests * Address reviewer comments. Just adds some TODOs to indicate deprecated layouts in our reflection. Our strategy is to leave the reflection code broad (covering deprecated features), but keep the builder concepts narrow. Once we've removed deprecated features from all instances, we can remove them from reflection. Also add a comment to the cmake to explain the unit test target test_conv_builder. * Addressed more reviewer comments. * Remove duplicate PassThrough::name Accidentally added this field to the end of the struct, too. The `name` field should be a the start of the struct for consistency.
Builder
This directory contains the experimental builder feature for composable_kernel.
- Status: In development (October - November 2025)
Overview
The builder provides a high-level, semantically-clear interface for constructing composable kernel operations, with an initial focus on convolution kernels for MIOpen. It leverages modern C++20 features (such as POD structs as non-type template parameters, concepts, and designated initializers) to simplify kernel instantiation and improve developer experience.
This project is a prototype for a more general builder pattern for all of composable_kernel (CK) and CKTile, but is currently limited to formalizing the interface between MIOpen and CK.

CMake Configuration
To enable the experimental builder, configure your build with:
cmake \
-D CMAKE_PREFIX_PATH=/opt/rocm \
-D CMAKE_CXX_COMPILER=/opt/rocm/bin/hipcc \
-D CMAKE_BUILD_TYPE=Release \
-D GPU_TARGETS="gfx942;gfx950" \
-D CK_EXPERIMENTAL_BUILDER=ON \
-D CMAKE_CXX_STANDARD=20 \
-G Ninja \
..
Building and testing
During development, build and test from the CK build directory with
ninja test_conv_builder && bin/test_conv_builder
