** Changed in: hipcub (Ubuntu)
Status: New => In Progress
** Description changed:
[ Impact ]
- hipcub 7.2.3 (libhipcub-dev) is a header-only C++ GPU algorithm library
wrapping
+ hipcub 7.2.4 (libhipcub-dev) is a header-only C++ GPU algorithm library
wrapping
rocPRIM on ROCm. This release brings one functional addition and one
test-side fix relative to 7.1.1:
1. Experimental SPIR-V back-end support — The build system now includes
optional
- SPIR-V compilation paths, allowing hipCUB to target SPIR-V-capable devices
- experimentally. No existing behaviour is altered; this path is disabled
unless
- explicitly requested at build time.

2. Memory leak fixes in unit tests — Several unit test binaries contained
improper

effect

Packaging changes in this upload (no user-visible behaviour change once
installed):
- d/rules: updated to use llvm22 toolchain paths.
- d/control, d/copyright, d/upstream/metadata, d/watch: updated for the 7.2.x
- monorepo layout.
+ monorepo layout.
The library is header-only; no object code or SONAME is shipped, so reverse
dependencies are unaffected at the binary level.
[ Test Plan ]
1. Build:
- - sbuild or dpkg-buildpackage succeeds.
- - dpkg --compare-versions confirms 7.2.3-0ubuntu1 > 7.1.1-0ubuntu1.
- - No .symbols file exists (hipcub is header-only); dpkg-gensymbols is not
- applicable.
+ - sbuild or dpkg-buildpackage succeeds.
+ - dpkg --compare-versions confirms 7.2.4-0ubuntu1 > 7.1.1-0ubuntu1.
+ - No .symbols file exists (hipcub is header-only); dpkg-gensymbols is not
+ applicable.
2. Installability:
- - apt install libhipcub-dev libhipcub-tests.
- - Confirm reverse dependencies remain installable without rebuild.
+ - apt install libhipcub-dev libhipcub-tests.
+ - Confirm reverse dependencies remain installable without rebuild.
3. Autopkgtest:
- - Run autopkgtest suite (command1:
/usr/libexec/rocm/libhipcub-tests/run-tests;
- Architectures: amd64, arm64).
- - All tests pass.
- Output:
- ```

[ Where problems could occur ]
* The d/rules update to llvm22 paths is an infrastructure-only change; any
- regression would manifest as a build failure rather than a library
misbehaviour.
