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 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

Jerome Robert b17ccb4c5c Fix a segfault in gemv when MAX_STACK_ALLOC is set
* stack_alloc_size is needed after the implementation call
but it may be overwritten if it's optimized to a register,
because some gemv implementation (ex: dgemv_n.S) do not
restore all register (ex: r10).
* do the same in ger.c for the same reasons even if the bug
has not been observed.
2015-01-29 09:55:57 +01:00
Hank Anderson 5eefe18ae4 Added CMakeLists.txt for the first of the BLAS folders.
It only does the double precision compile currently.

I realized I didn't finish converting Makefile.system yet, so I made
a note of that.
2015-01-27 16:17:17 -06:00
Jerome Robert e9d9a8eae3 Allow to do gemv and ger buffer allocation on the stack
ger and gemv call blas_memory_alloc/free which in their turn
call blas_lock. blas_lock create thread contention when matrices
are small and the number of thread is high enough. We avoid
call blas_memory_alloc by replacing it with stack allocation.
This can be enabled with:
make -DMAX_STACK_ALLOC=2048
The given size (in byte) must be high enough to avoid thread contention
and small enough to avoid stack overflow.
