b14f34e97c [CK] Work around staging compiler lifetime warning (#4419)
## Motivation
The staging compiler enables lifetime-safety warnings and we already
worked around a few of them.
This works around a few more instances that came up recently on gfx950
builds.
The initial PR that resolved most issues:
https://github.com/ROCm/composable_kernel/pull/3640

## Technical Details
This follows the pattern to locally ignore the newly added
lifetime-safety warnings that were moved from experimental to production
in upstream LLVM.
As a result, CK turned them on and treats them as errors, which prevents
the staging compiler from building CK.

## Test Plan

## Test Result

d0b17aab8b [CK] Optimize multi-dimensional static for loop decomposition (#4447)
## Motivation
Recursive template implementations might initially seem attractive to
minimize necessary coding.

Unfortunately, this style is often affects readability and requires
significant resources from the compiler to generate instantiation
chains. In "high-traffic" code (e.g., used in many places + compilation
units), this generally does not scale well and can bloat the overall
compile times to unnecessary lengths.

The aim of this PR is to take some of most high-traffic utility code and
try our best to eliminate recursive templates in favor of fold
expansions and constexpr function helpers.

In local tests with clang build analyzer,
device_grouped_conv2d_fwd_xdl_ngchw_gkcyx_ngkhw_f16_16x16_instance.cpp
showed high hit-rates on slow template instantiations in static_for,
dimensional static_for (static_ford), which are subsequently affected by
implementation of the Sequence class and associated transforms.

Example:
**** Templates that took longest to instantiate:
70111 ms: ck::detail::applier<int, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 1... (372 times, avg 188 ms) // **70 seconds!**

The above is part of the implementation of static_for which uses
Sequence classes..


## Technical Details

### Summary of Optimization Techniques

| Technique | Used In | Benefit |
 |-----------|---------|---------| 
| __Constexpr for-loop computation__ | sequence_reverse_inclusive_scan,
sequence_map_inverse | Moves O(N) work from template instantiation to
constexpr evaluation |
| __Pack expansion with indexing__ | sequence_reverse, Sequence::Modify
| Single template instantiation instead of recursive |
| __Flat iteration + decomposition__ | ford, static_ford | O(1) template
depth instead of O(N^D) |
| __Pre-computed strides__ | index_decomposer | Enables O(1)
linear-to-multi-index conversion |

### Impact on Compile Time

These optimizations reduce template instantiation depth from O(N) or
O(N^D) to O(1), which:

1. Reduces compiler memory usage
2. Reduces compile time exponentially for deep instantiation chains
3. Enables larger iteration spaces without hitting template depth limits


## Test Plan

* Existing tests for Sequence are re-used to affirm correctness
* Unit tests for ford and static_ford are added (dimensional looping)
* 8 new regression tests specifically verify the fixes for the PR
feedback:

  - `NonTrivialOrder3D_201` - Tests Orders<2,0,1> for static_ford
  - `NonTrivialOrder3D_201_Runtime` - Tests Orders<2,0,1> for ford
- `ConsistencyWithNonTrivialOrder_201` - Verifies static_ford and ford
consistency
  - `NonTrivialOrder3D_120` - Tests Orders<1,2,0> for static_ford
  - `NonTrivialOrder3D_120_Runtime` - Tests Orders<1,2,0> for ford
  - `NonTrivialOrder4D` - Tests 4D with Orders<3,1,0,2> for static_ford
  - `NonTrivialOrder4D_Runtime` - Tests 4D with Orders<3,1,0,2> for ford
- `AsymmetricDimensionsWithOrder` - Tests asymmetric dimensions with
non-trivial ordering


## Test Result

#### Commits in Range (8 commits)

1. `fd4ca17f48` - Optimize sequence_reverse_inclusive_scan and
sequence_reverse
2. `7a7e3fdeef` - Optimize sequence_map_inverse
3. `92855c9913` - Optimize ford and static_ford calls to eliminate
nested template recursion
4. `88a564032b` - Add unit tests for ford and static_ford
5. `1a0fb22217` - Fix clang-format
6. `8a0d26bddf` - Increase template recursion depth to 1024
7. `dc53bb6e20` - Address copilot feedback and add regression tests
8. `477e06861d` - Increase bracket depth to 1024

#### Build Timing Results

| File | Base (8b72bc8759d9 | HEAD(a0438bd398) | Improvement | 
|------|------|------|-------------| 
| grouped_conv2d_fwd (f16) -j1 | 313.31s | 272.93s | __12.9% faster__ | 
| grouped_conv1d_fwd (bf16) -j1 | 79.33s | 68.61s | __13.5% faster__ | 
| grouped_conv1d_bwd_weight (f16) -j1| 15.77s | 14.31s | __9.2% faster__
|
| device_grouped_conv2d_fwd_instance -j64 | s | s | __% faster__ |


#### Key Optimizations

1. __sequence_reverse_inclusive_scan/sequence_reverse__: O(N) → O(1)
template depth
2. __sequence_map_inverse__: O(N) → O(1) template depth
3. __ford/static_ford__: O(N^D) → O(1) template depth using flat
iteration with index decomposition
4. __Copilot feedback fixes__: Corrected New2Old mapping for non-trivial
orderings

6ed0dde669 [CK] Optimize vector type build times (#4471)
**Supercedes https://github.com/ROCm/rocm-libraries/pull/4281 due to CI
issues on import**

## Proposed changes

Build times can be affected by many different things and is highly
attributed to the way we write and use the code. Two critical areas of
the builds are **frontend parsing** and **backend codegen and
compilation**.

### Frontend Parsing
The length of the code, the include header tree and macro expansions all
affect the front-end parsing time.
This PR seeks to reduce the parsing time of the dtype_vector.hpp
vector_type class by reducing redundant code by generalization.
* Partial specializations of vector_type for native and non-native
datatypes have been generalized to one single class, consolidating all
of the data initialization and AsType casting requirements into one
place.
* The class nnvb_data_t_selector (e.g., Non-native vector base dataT
selector) class has been removed and replaced with scalar_type
instantiations as they have the same purpose. Scalar type class' purpose
is already to map generalized datatypes to native types compatible with
ext_vector_t.

### Backend Codegen
Template instantiation behavior can also affect build times. Recursive
instantiations are very slow versus concrete instantiations. The
compiler must make multiple passes to expand template instantiations so
we need to be careful about how they are used.
* Previous vector_type classes declared a union storage class, which
aliases StaticallyIndexedArray<T,N>.
```
template <typename T>
struct vector_type<T, 4, typename ck::enable_if_t<is_native_type<T>()>>
{
    using d1_t = T;
    typedef T d2_t __attribute__((ext_vector_type(2)));
    typedef T d4_t __attribute__((ext_vector_type(4)));

    using type = d4_t;

    union
    {
        d4_t d4_;
        StaticallyIndexedArray<d1_t, 4> d1x4_;
        StaticallyIndexedArray<d2_t, 2> d2x2_;
        StaticallyIndexedArray<d4_t, 1> d4x1_;
    } data_;
   ...
};
```
* Upon further inspection, StaticallyIndexedArray is built on-top of a
recursive Tuple concatenation.
```
template <typename T, index_t N>
struct StaticallyIndexedArrayImpl
{
    using type =
        typename tuple_concat<typename StaticallyIndexedArrayImpl<T, N / 2>::type,
                              typename StaticallyIndexedArrayImpl<T, N - N / 2>::type>::type;
};
```
This union storage has been removed from the vector_type storage class. 

* Further references to StaticallyIndexedArray have been replaced with
StaticallyIndexedArray_v2, which is a concrete implementation using
C-style arrays.
```
template <typename T, index_t N>
struct StaticallyIndexedArray_v2
{
    ...

    T data_[N];
};
```

### Fixes
* Using bool datatype with vector_type was previously error prone. Bool,
as a native datatype would be stored into bool ext_vector_type(N) for
storage, which is a packed datatype. Meaning that for example,
sizeof(bool ext_vector_type(4)) == 1, which does not equal
sizeof(StaticallyIndexedArray<bool ext_vector_type(1), 4> == 4. The
union of these datatypes has incorrect data slicing, meaning that the
bits location of the packed bool do not match with the
StaticallyIndexedArray member. As such, vector_type will use C-Style
array storage for bool type instead of ext_vector_type.
```
template <typename T, index_t Rank>
using NativeVectorT = T __attribute__((ext_vector_type(Rank)));

sizeof(NativeVectorT<bool, 4>) == 1  (1 byte per 4 bool - packed)
element0 = bit 0 of byte 0
element1 = bit 1 of byte 0
element2 = bit 2 of byte 0
element3 = bit 3 of byte 0

sizeof(StaticallyIndexedArray[NativeVectorT<bool, 1>, 4] == 4  (1 byte per bool)
element0 = bit 0 of byte 0
element1 = bit 0 of byte 1
element1 = bit 0 of byte 2
element1 = bit 0 of byte 3

union{
    NativeVectorT<bool, 4> d1_t;
    ...
    StaticallyIndexedArray[NativeVectorT<bool,1>, 4] d4x1;
};

// union size == 4 which means invalid slicing!
```
* Math utilities such as next_power_of_two addressed for invalid cases
of X < 2
* Remove redundant implementation of next_pow2

### Additions
* integer_log2_floor to math.hpp
* is_power_of_two_integer to math.hpp

9b81070cf3 [Conv] Add NumGroupsToMerge to BwdWeight type string (#4271)
## Proposed changes

Add parameter to bwd weight V3 type string showing the number of groups
to merge. This is required for MIOpen to be properly tuned since it uses
type strings for performance database entries.

In order to not break existing tuning databases, the parameter is added as a named suffix and only when group merging is enabled.

470f031e58 [Compiler] Addressing new compiler warnings (#3640)
* [Compiler] Addressing new compiler warnings

Clang enables new lifetime warnings in production and we see build
errors due to this with the staging compiler.

The attributes added in this PR are suggested by the compiler. However,
I'm not very familiar with the code base, so the changes may be
incorrect.

* Update some more instances

* Adds file-level ignores via clang diagnostic pragma

The number of instances was large, so I decided to use file-level scope
to disable the warning via pragma clang diagnostic ignored.

It also showed this warning coming from the gtest dependency. For that,
I did add the respective command line flag to the CMake variables. I
don't know if this is acceptable or not.

* This adds the remaining instances

For a build on gfx90a.

* fix clang format

* Adding couple more instances from gfx1200 build

* Fixed another few instances

- grouped_conv2d_fwd_dynamic_op
- grouped_conv3d_fwd_dynamic_op
- grouped_conv3d_fwd_bilinear
- grouped_conv3d_fwd_convscale

- grouped_conv3d_fwd_scaleadd_scaleadd_relu

* Fix incomplete parsing of types from source names in add_instance_library() cmakelists function so we don't build f8 on RDNA3.

* Do not build f8 / bf8 only flavor tests on RDNA3

* Make sure we have proper generic instances for all instance lists related to the post-ces extra flavors, with scalarPerVector = 1. Then disable all but one generic instance per instance list to reduce compile time.

* Post rebase fix: Template parameters for Grouped Conv Fwd Device Impl got tweaked upstream.

* adding int8 and fp16 overloads to the elementwise operations

* fixed copilot nits

* Addressing review comments:

- removed unnecessary examples for dynamic op
- removed unnecessary conv specalizations for all the flavors
- removed spurious bilinear and scale source files

* clang-format

* reduced no of tests

97d6e59580 [CK_BUILDER] Integrate CKB validation with CK verification (#3649)
* ck-builder: tensor copy function

This function copies one tensor to another, so that the memory
layout can be changed between them.

* ck-builder: fix ck::bhalf literals

These types don't work properly.

* ck-builder: abstract compare_elements in gpu_verification.hpp and make builder use it

This reduces the amount of duplicated code a bit.

* ck-builder: add flat tensor iterator

This "iterator" type pretends to be a pointer, useful for passing
tensors to functions expecting pointer-like types.

* ck-builder: integrate validation with ck gpu verification

By templating the gpu_verify function over iterators, we can use
the new FlatTensorIterator to adapt the function to multi-
dimensional tensors without changing either implementation
too much.

* ck-builder: add check_by_accumulations

This changes the gpu_verification.hpp code to also accept "iterator"
types for the relevant gpu_verify and gpu_reduce_max functions.

* ck: fix test_gpu_verification GenerateRandomData for bhalf

is_integer_it<bhalf_t> yields true, but it is not actually
an integer.

* ck: make gpu_verification kernels be proper persistent kernels

Previously these were using a hardcoded value for the grid size. This
commit changes that so that the grid size is automatically derived
from the kernel's occupancy and the number of multiprocessors on
the GPU.

* ck: clean up gpu_verification.hpp using block_reduce

This implements a small generic block reduce function, and rewrites
the rest of gpu_verification.hpp using that function to clean it up
a bit.

* ck-builder: doc typos

* ck-builder: update testing readme with validation interface.

* ck-builder: rebase fixes + review comments

* ck-builder: fix device integer generation with float types

Passing bfloat here causes a nans due to type_convert performing
a bitcast.

* ck: another bhalf_t bug

CK expects that int-generation with ck::bhalf_t yields bhalf integers,
not unsigned integers. This makes the logic of FillUniformRandInteger
compatible with GeneratorTensor_2<InDataType>, however idiotic that
may be.

078912ec20 Add build time optimization documentation (#3608)
This document describes techniques for reducing C++ template instantiation
overhead in the Composable Kernel codebase, including:

- Replacing recursive templates with pack expansion (O(N) → O(1) depth)
- Using named functors instead of lambdas to share instantiations
- Replacing template recursion with constexpr loops
- Using fold expressions for accumulation operations

These techniques can significantly reduce build times for template-heavy code.

bebf8c3720 Optimize sequence metaprogramming utilities to reduce template instantiation depth (#3585)
This change significantly improves compile-time performance by reducing template
instantiation depth for sequence generation and merging operations:

Optimizations:
- sequence_gen: Reduce instantiation depth from O(log N) to O(1) by using
  __make_integer_seq to generate indices in a single step, then applying the
  functor via pack expansion
- uniform_sequence_gen: Similarly optimized to O(1) depth using __make_integer_seq
  with a helper that applies a constant value via pack expansion
- sequence_merge: Reduce depth from O(N) to O(log N) using binary tree reduction
  strategy. Added direct concatenation specializations for 1-4 sequences to
  avoid recursion in common cases, falling back to binary tree merging for 5+
  sequences

Documentation:
- Added extensive inline comments explaining why sequence_merge cannot achieve
  O(1) depth like sequence_gen (requires computing cumulative sequence lengths
  from heterogeneous inputs, inherently requiring recursion)
- Documented the binary tree reduction approach and why it's superior to fold
  expressions for this use case

Testing:
- Added comprehensive unit tests for uniform_sequence_gen with different values,
  sizes, and edge cases
- Added tests for sequence_gen with custom functors (double, square, identity,
  constant) to verify the new implementation works with arbitrary functors
- Added tests for sequence_merge with 4, 5, and many sequences to verify both
  the direct concatenation path and binary tree reduction path
- Added tests for empty sequence edge cases
