[Octave-bug-tracker] [bug #57033] Replace CXSPARSE with SPQR

[Rik]

Follow-up Comment #32, bug #57033 (project octave):

Regarding issue #1, duplicate BIST tests: it was my understanding that using
SPQR is not just higher performance, it actually gets the correct answer.  If
this is the case then one choice would be to drop support for CXSPARSE and
only support SPQR.  If that change is made then we can easily change the BIST
tests to


%!testif HAVE_SPQR


If that is not possible then we can still just use one BIST test, but we can't
use a static test for a library because the syntax for %!testif only supports
ANDing of multiple libraries.  In that case, we can change to a runtime
configuration test.


%!testif ; __have_feature__ ("SPQR") || __have_feature__ ("CXSPARSE")
