Jerome Robert d346c533b1 Fix z/ctrmv stack allocation on AMD bulldozer and barcelona target

Werner Saar 41000c8443 added directory for optimized lapack fortan codes and added dlaqr5.f 2016-05-31 12:53:07 +02:00
John Biddiscombe 053044ae4d Replace CMAKE_SOURCE_DIR/CMAKE_BINARY_DIR with PROJECT_SOURCE_DIR/PROJECT_BINARY_DIR 
If OpenBLAS is built using add_subdirectory(OpenBlas) as part of another project
then the paths set by CMAKE_XXX_DIR are relative to the parent project
and not the OpenBLAS project.

Jerome Robert 32f793195f Use stack allocation in zgemv and zger 
For better performance with small matrices
Ref #727
 2016-02-08 11:24:21 +01:00
Jerome Robert 1fe3aab047 Use GEMM_MULTITHREAD_THRESHOLD as a number of ops 
...not a matrix size. For GEMM_MULTITHREAD_THRESHOLD=4
(the default value) this does not change anything but
for other values it make the GEMM and GEMV thresholds
changing in the same way.

Close #742

Jerome Robert 1a1935507b [z]ger: increase multithread threshold 
The ones given in 3ae30cd was by far to low because I
mixed m and m*n in my measures. Note that the new ones
are closed to the [z]gemv ones which is comforting
that both are right.

Martin Koehler 711ca33bc6 Improved Ximatcopy when lda==ldb. 
The Ximatcopy functions create a copy of the input matrix
although they seem to work inplace. The new routines
XIMATCOPY_K_YY perform the operations inplace if the leading
dimension does not change.

Zhang Xianyi 9798481979 Refs #478, #482. Fix segfault bug for gemv_t with MAX_ALLOC_STACK flag. 
For gemv_t, directly use malloc to create the buffer.

Zhang Xianyi cdefdb21cd Refs #492. Fixed c/zsyr bug with negative incx. 2015-02-26 06:37:03 +08:00
Hank Anderson 0d8e227ea7 Changed strategy for setting preprocessor definitions. 
Instead of generating separate object files for each permutation of
defines for a source file, GenerateNamedObjects now writes an entirely
new source file and inserts the defines as #define c statements.

This solves a problem I ran into with ar.exe where it was refusing to
link objects that had the same filename despite having different paths.

Hank Anderson b2284647a3 More complex objects. 2015-02-23 07:51:05 -06:00
Hank Anderson a6116e5859 Added some more complex-only objects. 2015-02-22 17:49:28 -06:00
Hank Anderson 67e39bd8fb Added mangled complex filenames to interface and lapack CMakeLists.txt. 2015-02-17 13:12:30 -06:00
Hank Anderson 9eb1499095 Added another param to GenerateNamedObjects to mangle complex source names. 
There are a lot of sources for complex float types that are the same
names as the real sources, except with z prepended.

Martin Koehler 39cc6b21d3 Add ATLAS-style ?geadd function 2015-02-16 13:46:20 +01:00
Hank Anderson 4662a0b13a Changed generate functions to iterate through a list of float types. 
This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.

Hank Anderson e74462a3f5 Moved declarations to start of functions to satisfy MSVC C89 implementation. 2015-02-11 11:16:57 -06:00
Hank Anderson e8c39138c6 Removed return value from GenerateNamedObjects. 
It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.
 2015-02-09 12:28:09 -06:00
Hank Anderson 58cff2fed8 Added CBLAS define/naming convention to GenerateNamedObjects. 2015-02-04 11:30:15 -06:00
Hank Anderson 5690cf3f0e Added override for function names in GenerateNamedObjects. 
The BLAS interface folder should now be generated the correct objects
for the DOUBLE case.
 2015-02-04 10:52:19 -06:00
Hank Anderson a0aeda6187 Added function to set defines for the object names (e.g. -DNAME=dgemm). 2015-02-04 10:37:34 -06:00
Hank Anderson 20e593a44a Added cblas_ objects to interface CMakeLists. 
Naming isn't right, though, not seeing cblas_xxxx exports in the
resulting library.

Hank Anderson 9e154aba58 Added LAPACK object files to interface CMakeLists. 2015-02-02 12:31:15 -06:00
