Revert "Avoid taking root of negative number in symv_thread.c" 2019-10-01 23:50:41 +02:00
Sebastian Berg 6355c25dde Avoid taking root of negative number in symv_thread.c 
This is similar to fixes in gh-1929, but there was one remaining
occurance of this type of pattern in the driver/level2/*_thread.c
files.

Correct range_n limiting 
same bug as seen in #1388, somehow missed in corresponding PR #1389

Re-enable loop unrolling in trmv and remove the scary warning 
fixes #1748 as that half of the fix for #1332 appears to have been an overreaction on my part.

Allow optimization for small m, large n only if it can be made threadsafe 
otherwise the introduction of a static array in 8e5a108 to improve #532 breaks concurrent calls from multiple threads as seen in #1844

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.

Hank Anderson ab7043373f Fixed bug generating trmv complex source names. 2015-02-24 15:18:41 -06:00
Hank Anderson 0553476fba Added TRANS defines for complex sources in lapack. 2015-02-24 14:30:35 -06:00
Hank Anderson 2416d9dbac Fixed TRANSA defines for complex sources in driver/level2. 2015-02-24 13:18:07 -06:00
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.

Added loop to build objects with different KERNEL defines.

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 e8c39138c6 Removed return value from GenerateNamedObjects. 
It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.
