This was introduced in ROCm-5.3, see https://github.com/ROCm/ROCR-Runtime/blob/rocm-5.3.x/src/inc/hsa_ext_amd.h#L333. The `dynamic_hsa/` version is a copy of this header for use when the system version is not provided. If the system fails to find HSA, then it will use the dynamic version. The problem here is that you _have_ HSA, but it's too old. I don't know how much backward compatibility we really provide here, unfortunately the HSA headers really don't give you much versioning to work with, so we can't do `ifdef` on this stuff. https://github.com/llvm/llvm-project/pull/95484 ___ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits

It can be used just by saving it as `llvm-bug95484` and running it by doing
either:
- `./llvm-bug95484`
to fetch and attempt a clean build of `release/18.x` in a way it reproduces
the bug,
- `./llvm-bug95484 17`
to fetch and reproduce the bug with `release/17.x`.
It will fail this way:
```

The error I see comes from the fact there is no old HSA around to workaround an LLVM bug. There is no `hsa/hsa.h` in the tree, the default `dynamic_hsa` is not used. The `hsa/hsa.h` file is from ROCm, not from LLVM. Without such patch, LLVM requires ROCm to be installed and configured to be in default includes for `src/rtl.cpp` to build if `hsa.cpp` is not built. This patch is to make LLVM use `dynamic_hsa` for building `src/rtl.cpp` because it is the default. This patch is needed to build both `release/17.x` and `release/18.x`, the `main` branch changed the code layout so the patch will not work. I assume a full LLVM build will not trigger the build problem because something else will include `dynamic_hsa` and will make it findable by `src/rtl.cpp` by luck. But when building a not-full LLVM, just what's needed by some applications, `dynamic_hsa` is not added to the include directories while being required by `src/rtl.cpp`. https://github.com/llvm/llvm-project/pull/95484 ___ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits

We could special-case null pointers, but they're already covered by the
diagnostic, which asks for global variables or functions – which NULL isn't.
For auth/sign, we don't have that sort of constraint on the pointer: it really
is NULL and NULL alone that's special.
Now, the more interesting question is whether we should allow null pointers at
all here. Since defining these original builtins we have taught the qualifier
to have a mode that signs/authenticates null, for some specific use-cases where
replacing a signed value with NULL (which is otherwise never signed or
authenticated) would bypass signing in a problematic way.
We haven't had the chance or need to revisit the builtins to allow sign/auth of
NULL, but it's reasonable to add that support in the future. We'd have to
consider how to expose that in the builtins, because it's probably still
something that's almost always a mistake; more builtins would be an easy
solution but maybe not a sophisticated one.

It should then always be included or the build will fail if only `src/rtl.cpp`

[llvm-branch-commits] [llvm] AMDGPU: Fix buffer load/store of pointers (PR #95379)
krzysz00 wrote:
On the other hand, it's a lot easier to handle ugly types down in instruction
selection, where you get to play much more fast and loose with types.
And there are buffer uses that don't fit into the fat pointer use use case
where we'd still want them to work.
For example, both `str
uct.ptr.bufferload.v6f16` and `struct.ptr.buffer.load.v3f32` should be a
`buffer_load_dwordx3`, but I'm pretty sure 6 x half isn't a register type.
The load and store intrinsics are already overloaded to handle various {8, 16,
..., 128}-bit types, and it seems much cleaner to let it support any type of
those lengths. It's just a load/store with somewhat weird indexing semantics,
is all.
And then, since we're there ... `load i256, ptr addrspace(1) %p` legalizes to
multiple instructions, and `{raw,struct}.ptr.buffer.load(ptr addrspace(8) %p,
i32 %offset, ...)` should too. It's just a load, after all.

Subject: [PATCH] [SystemZ] Bugfix in getDemandedSrcElements(). (#88623)
For the intrinsic s390_vperm, all of the elements are demanded, so use
an APInt with the value of '-1' for them (not '1').
Fixes https://github.com/llvm/llvm-project/issues/88397
(cherry picked from commit 7e4c6e98fa05f5c3bf14f96365ae74a8d12c6257)

I’m leaning towards the block count heuristic now. I think the 1M and 4x1K exec
count block case is likely pretty common – I imagine functions with loops would
look a lot like this. Having some blocks matched exactly would suggest to me
that there would likely be a reasonable amount of similarity between the
profiled function and existing function relationally, which block coldness
likely doesn’t have an outsized bearing on. I think having a reasonably high
threshold for matched blocks would conservatively allow us to drop functions in
high discrepancy – I’ll test this on a production binary.

krzysz00 wrote: Yeah, makes sense. ... what prevents a match-bitwidth operator from existing? Context from where I'm standing is that you should be able to `raw.buffer.load/store` any (non-aggregate, let's say, since that could be better handled in `addrspace(7)` handling) type you could `load` or `store`. That is, `raw.ptr.buffer.load.i15` should work (as an i16 load that truncates) as should `raw.ptr.buffer.store.v8f32` (or `raw.ptr.buffer.store.i256`). Sure, the latter are two instructions long, but regular loads can regularize to multiple instructions just fine. My thoughts on how to implement that second behavior were to split the type into legal chunks and add in the offsets, and then merge/bitcast the values back. https://github.com/llvm/llvm-project/pull/95379 ___ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits

arsenm wrote: That's what we've traditionally done and I think we should stop. We currently skip inserting the casts if the type is legal. It introduces extra bitcasts, which have a cost and increase pattern match complexity. We have a bunch of patterns that don't bother to look through the casts for a load/store https://github.com/llvm/llvm-project/pull/95379 ___ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
[llvm-branch-commits] [llvm] AMDGPU: Fix buffer load/store of pointers (PR #95379)
krzysz00 wrote: So, general question on this patch series: Wouldn't it be more reasonable to, instead of having separate handling for all the possible register types, always do loads as `i8`, `i16`, `i32` `<2 x i32>`, `<3 x i32>, or `<4 x i32>` and then `bitcast`/`merge_values`/... the results back to their type? Or at least to have that fallback path - if we don't know what a type is, load/store it as its bits? (Then we wouldn't need to, for example, go back and add a `<16 x i8>` case if someone realizes they want that) https://github.com/llvm/llvm-project/pull/95379 ___ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits

[llvm-branch-commits] [compiler-rt] [TySan] Fixed false positive when accessing offset member variables (PR #95387)
llvmbot wrote:
@llvm/pr-subscribers-compiler-rt-sanitizer
Author: None (gbMattN)
Changes
This patch fixes a bug the current TySan implementation has. Currently if you
access a member variable other than the first, TySan reports an error. TySan
believes you are accessing the struct type with an offset equal to the offset
of the member variable you are trying to access.
With this patch, the type we are trying to access is amended to the type of the
member variable matching the offset we are accessing with. It does this if and
only if there is a member at that offset, however, so any incorrect accesses
are still caught. This is checked in the struct-members.c test.

Yes. Threshold of course need to be tuned based on the heuristic chosen. I just
feel that block count based threshold could be a better proxy of how confident
we are about the graph match and whether stale profile matching should
proceed.. But I don't have very strong opinion.

It's a tricky question how to define the cutoff in terms of sufficient matching.
I first thought of defining a block count based cutoff (if we matched >5% of
blocks, proceed with matching), but then what if these are cold blocks covering
<1% of exec count? In this case we'd end up guessing/propagating most samples.
For block-based matching, the threshold should be higher than 5%, perhaps
closer to a half? For exec count based matching, I'd feel comfortable with 5%
as threshold.

Trying to understand the rationale behind using dynamic counts to determine
whether profile inference is safe.
The way I see it is, we have two graph that we try to match, if we have many
nodes in the graph that we have exact match, chances are higher that we can
infer the correct match for the rest of the nodes. With that, we care about
more how many nodes we can match statically.
Say if we have 5 blocks with count distribution of 1M, 1K, 1K, 1k, 1K, if we
have exact match for the 4 1K node (80% exact match), we should feel reasonably
confident about inferring the remaining 1 node, even though if we look at
counts, we have exact match for only <1%.
WDYT?
