Package: libxsimd-dev
Version: 14.0.0-2
Severity: serious
Justification: debci
X-Debbugs-Cc: [email protected]
User: [email protected]
Usertags: ppc64el
Control: forwarded -1 https://github.com/xtensor-stack/xsimd/issues/1257
Control: affects -1 src:llvm-toolchain-21
xsimd 14.0.0 tests on ppc64el are passing with gcc 15 but failing with
clang 21.
If gcc is fine, is there a clang option we should apply,
or should it be consider a bug in clang?

Closes: 1127626
Changes:
xsimd (14.2.0-1) unstable; urgency=medium
.
* Team upload.
* New upstream release
- applies debian patch fix_arm64_PR1241.patch
* update debian patch clang_ppc64el.patch to upstream PR#1337.
Fixes clang handling of vsx on ppc64el.
debian/tests: reenable clang tests on ppc64el.
Closes: #1127626
* debian patch support_xtl_standards.patch hardcodes the required
CXX standard to match the one (cxx_std_17) required by xtl for
complex number support. Otherwise there is a breaking discrepancy
with the default standard (cxx_std_14) and the installed xsimd
cmake config files if an application does not explicitly request
-DENABLE_XTL_COMPLEX=On. In particular required in
tests/CMakeFiles.txt. See Bug#1135592 (upstream issue#1338)
