Thank you very much Sven.
ROTM is actually used in LAPACK by some new routines.
I believe I will change the GOTO in DROTMG, and proceed to further change in
the BLAS (adding testing) for the next major Release.
Best,
Julie

Hi Julie,
drotmg and srotmg are part of the original BLAS (the we now call the Level 1
BLAS). drotm and srotm are also part of the original BLAS and do not seem to
be tested either. I imagine that because LAPACK does not use them, those
tests got eliminated.
If you go to the ACM Collected algorithms (www.netlib.org/toms/) you can find
original source of the BLAS as algorithm 539. There is a tester for the
modified Givens routines as part of algorithm 539.
At least two other routines, sdsdot and dsdot are also part of the original
BLAS and I think that they have been dropped completely from the LAPACK set.
But, again they are in the ACM collection and are tested there.
Hope that helps, best wishes,
Sven.
