See build error log from https://github.com/ROCm/composable_kernel/issues/2271#issuecomment-3150218542 This PR make vector element access constexpr-safe by avoiding operator[] on ext_vector_type(2) and replace those sites in the pk_fp4 conversions so they can be used in constant expressions, as The operator[] on ext_vector_type(2) isn't allowed in constant expressions, which caused "constexpr function never produces a constant expression" with a note at x[0]. Using `bit_cast` to a trivial array representation keeps it constexpr-compatible. Signed-off-by: Hollow Man <hollowman@opensuse.org>
ck_tile/core
ck_tile/core contains every basic functions and structures to create a GPU kernel using ck_tile. User should only include ck_tile/core.hpp this single header to use all the functionality. Everything is under ck_tile namespace. The coding style under this folder should be similar to std (snake_case for structure/function, Camel for template types...)
algorithm/
coordinate transform and some other reusable algorithm
arch/
contains some basic device building block like mma, buffer addressing, etc...
container/
contains basic container data structure, array/sequence/tuple/...
numeric/
data type, and data type related math
tensor/
tensor descriptors and tile level API
utility/
other utility function for both host/device
