Note: issue (1) was fixed in previous commit
Message from David
(1) Line 147 of SRC/zgetrf2.f contains the following code:
EXTERNAL ZGEMM, ZSCAL, ZLASWP, ZTRSM, ZERBLA
Inspection of the zgetrf2.f code suggests that ZERBLA on line 147 should in fact be replaced by XERBLA.
--> [JULIE] This was fixed in our SVN on Dec 7th, 2015, revision 1664
(2) Lines 444 to 447 of TESTING\EIG\cdrvbd.f contains the following code:
EXTERNAL ALASVM, XERBLA, CBDT01, CBDT05, CGESDD, CGESVD,
$ CGESVJ, CGEJSV, CGESVDX, CLACPY, CLASET, CLATMS,
$ CUNT01, CUNT03
Since the length of line 445 is 73 characters the comma at the end of that line is truncated and a symbol CLATMSCUNT01 is erroneously defined. Then during linking an error is generated because this erroneously defined symbol cannot be found.
** Recommendation ** The developers reformat all code to ensure strict adherence to the standard 72 column formatting of fixed format source files. As is well known violation of this formatting rule can result in subtle undetected errors.
(3) Similar formatting errors to that in (2) have been detected in:
TESTING\EIG\zdrvbd.f (line 445)
TESTING\EIG\dchkbd.f (line 548)
TESTING\EIG\ddrvbd.f (line 407)
TESTING\EIG\derrbd.f (line 92)

EXTERNAL CHKXER, CGEES, CGEESX, CGEEV, CGEEVX, CGEJSV

There is a comma missing from the end of line 103. This does not result in a compilation error. Rather an invalid symbol CGEJSVCGESDD is defined which ultimately causes an error during linking.

Commit interface inconsistencies fix proposed by David Vowles on Jan 18th 2016 - sent directly to Julie
Confirmed by Julie on Jan 18th 2016
Routines: [cz]unbdb[1234].f, [SD]ORBDB[1234].f
== First Email from David ==
I have encountered some additional errors when compiling Lapack v3.6.0 with Compaq Visual Fortran. Interestingly, these errors did not occur when compiling with Intel Visual Fortran.
File: “SRC\cunbdb1.f” Lines: 310-312
C = SQRT( SCNRM2( P-I, X11(I+1,I+1), 1, X11(I+1,I+1),
$ 1 )**2 + SCNRM2( M-P-I, X21(I+1,I+1), 1, X21(I+1,I+1),
$ 1 )**2 )
The interface to the BLAS SCNRM2 function is SCNRM2(N,X,INCR) whereas the interfaces to the SCNRM2 function calls in “SRC\cunbdb1.f” are of the form SCNRM2(N, X1, INC1, X2, INC2).
Similar interface inconsistencies are found in the following files:
File: “SRC\cunbdb2.f” Lines: 299-300
File: “SRC\cunbdb3.f” Lines: 299-300
File: “SRC\cunbdb4.f” Lines: 347-349
The above inconsistencies between the interface of the function definition and the function call causes compilation failure of the test-function “xeigtstc.exe”
It is unclear if function calls of the form SCNRM2(N, X1, INC1, X2, INC2) should be replaced by SCNRM2(N, X1, INC1) or if some other correction is required.
== Second Email from David: ==
By the way, I found similar interface inconsistencies in the SRC\cunbdb<n>.f subroutines for <n> = 1 to 4;
and in the SRC\<t>ORBDB<n>.f subroutines for <t> = D and S and <n> = 1 to 4.
A total of 16 subroutines are affected – the four mentioned in my previous email and the twelve mentioned here.
After changing the calls in the affected files from *NRM2(N,X1,INC1,X2,INC2) to *NRM2(N,X1,INC1)
my build for Windows x86 with Compaq Visual Fortran (CVF) completed successfully and all tests passed.
But I do await your verdict as to whether the proposed modification to the function calls is correct.
If I understand correctly STDCALL is the default calling mechanism for the CVF compiler whereas for
the (Intel Visual Fortran) IVF compiler it is the C calling convention. I wonder if this difference
in calling convention explains why the affected test programs compile and link with IVF but fail to link with CVF.

email of Martin Köhler below
(1) add a quick return for N=0
(2) add a quick return for N=1
(3) no one reviewed this fix, feel free to comment
Dear LAPACK people,
I found a bug concerning the following function:
The xGETC2 is the level-2 BLAS implementation of an LU decomposition
with complete pivoting. Thereby, a "comparison depending on an
uninitialized value" appears if the input is an one-by-one matrix.
Namely the code in line 202 (LAPACK 3.5.0):
IF( ABS( A( N, N ) ).LT.SMIN ) THEN
accesses SMIN which is set in the previous DO loop. This loop is
only called if N > 1 and so SMIN is not set to a well defined value
if N = 1. But the documentation claims that all matrix N>=0 are
allowed. Furthermore if calling with N = 0 the quick return
statement is missing and the evaluation of ABS(A(N,N)) then yields
an out-of-bound memory violation.
These bug affect the real and the double precision code as well
as their complex counterparts from LAPACK 3.0 up to the current
LAPACK 3.6.
regards,
Martin Köhler

Correct workspace computation for [CZ]GESVDX when a workspace query is done
This is a bug report and a bug fix from Lawrence Mulholland from NAG.
Thanks Lawrence!
Also add a variable ITEMPR to index the real workspace RWORK as opposed to
using ITEMP. ITEMP is for complex workspace WORK, while ITEMPR is for the real
workspace RWORK. Sounds good.
Thanks Lawrence!

Fix upper case issue in CMakeLists reported by Julien Shueller on Nov 17th to Julie
In CBLAS/CMakeLists.txt:
configure_file(${CMAKE_CURRENT_SOURCE_DIR}/CMAKE/cblas-config-version.cmake.in
${LAPACK_BINARY_DIR}/cblas-config-version.cmake @ONLY)
configure_file(${CMAKE_CURRENT_SOURCE_DIR}/CMAKE/cblas-config-build.cmake.in
${LAPACK_BINARY_DIR}/cblas-config.cmake @ONLY)
The /CMAKE subdirectory should be lowercase, I guess some work on OSX which (still!) has a case-insensitive file-system.

Commit fix proposed by Julien Schueller
Sent to LAPACK mailing list on Nov 16th 2015
spotted a minor inconsistency in the lapacke cmake config files install directory location.
in CMakeLists.txt:
install(FILES
${LAPACK_BINARY_DIR}/CMakeFiles/lapack-config.cmake
${LAPACK_BINARY_DIR}/lapack-config-version.cmake
DESTINATION ${LIBRARY_DIR}/cmake/lapack-${LAPACK_VERSION}
)
in LAPACKE/CMakeLists.txt:
install(FILES
${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles/lapacke-config.cmake
${LAPACK_BINARY_DIR}/lapacke-config-version.cmake
DESTINATION lib/cmake/lapacke-${LAPACK_VERSION}
)
So lapack-config.cmake and lapacke-config-version.cmake could be installed in different directories in cases where CMAKE_INSTALL_LIBDIR is not set to "lib", eg Fedora or RHEL.
I propose to fix LAPACKE/CMakeLists.txt:
sed -i "s|DESTINATION lib/cmake/lapacke|DESTINATION \${LIBRARY_DIR}/cmake/lapacke|g" LAPACKE/CMakeLists.txt

Mistake in computation of workspace for ZGGEV3. When calling ZHGEQZ the
penultimate argument should be RWORK and not WORK. Easy to fix, not a big big
deal but some compilers might legitimatley complain.

Committing patch submitted by Christopher Conrad on Sept 25th 2015
From Christopher:
I noticed the following errors in the documentation and attached
patches for all of them:
- Sometimes the function name in the docstring \brief does not match the
actual function name (ex: xSYGV*).
- According to the documentation, xLAHRD is obsolete but not deprecated.
- The parameter N in xLA(R)SCL2 is not the number of columns of D.
Also, I updated the Doxyfile (doxygen -u DOCS/Doxyfile) and removed
the missing DOT_FONTNAME to get rid of the Doxygen warnings.

Thanks to Lawrence Mulholland (NAG) for reporting the problem. While the array
E should really be of size N-1, xSYCONV() is not ready for this and so, in the
comment at the header level, we now require E to be of size N. Also xSYTRS2()
is using E(N) = ZERO, so if we make E of size N-1 in xSYCONV(), then we need to
see the impact on xSYTRS2(). This is long term cleaning, so for now, we revert
back to requesting an array E of size N. Thanks Lawrence for noticing this.
