Package: sse3-support,isa-support
Version: 14
Severity: grave
Justification: Completely fails to serve its purpose
Hi,
on my Thinkpad X250 with an "Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz"
CPU, sse3-support version 14 fails to install where version 13 installs
fine, despite sse3-support's changelog entry for version 14 claims that
only the package description was changed -- which according to "git diff
debian/13..HEAD" (the "debian/14" tag seems missing) is not true as a
lot of Perl code changed as well.

│ Alas, your machine doesn't support the sse3 instruction set. It is needed by
software that depends on this dummy package. Sorry. │

This machine doesn't support sse3, sorry.
Aborting.

Additionally the package description claims "It is available on almost
any 64-bit-capable processor except for some early AMD models
(Sledgehammer and Clawhammer). This CPU is neither an AMD one nor an
early 64-bit CPU, being only about 7 years old.

power management:
This makes installation of libqt6webenginecore6 fail, where the the
debian/changelog entry of version 6.3.1+dfsg2-8 claims that the
maintainers added "the sse3-support dependency to libqt6webenginecore6
to ensure that x86 CPUs support SSE3 as Chromium 89+ requires it".
But chromium 105.0.5195.102-1 works totally fine on that Thinkpad, which
is another hint that sse3-support/14 isn't properly checking for sse3
support anymore but alerting without necessity.
So I digged a bit into the differences between sse3-support and
isa-support .debs of version 13 and 14. Here's what I found:
* preinst of sse3-support version 13 and 14 are identical. Especially
this line is identical:
5 FILE="/usr/libexec/x86_64-linux-gnu/isa-support/test-sse3"
* But isa-support 14 does not have such a file anymore, instead there is
now a file /usr/libexec/x86_64-linux-gnu/isa-support/test-SSE3. Note
the different capitalization.
* The same probably counts for sse4.1-support and sse4.2-support as
well:
Only in isa-support_13/usr/libexec/x86_64-linux-gnu/isa-support: test-sse3
Only in isa-support_13/usr/libexec/x86_64-linux-gnu/isa-support: test-sse4.1
Only in isa-support_13/usr/libexec/x86_64-linux-gnu/isa-support: test-sse4.2
Only in isa-support_14/usr/libexec/x86_64-linux-gnu/isa-support: test-SSE3
Only in isa-support_14/usr/libexec/x86_64-linux-gnu/isa-support: test-SSE4.1
Only in isa-support_14/usr/libexec/x86_64-linux-gnu/isa-support: test-SSE4.2
