Fix a segfault in gemv when MAX_STACK_ALLOC is set
 2015-01-29 18:23:50 +08:00
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.

8ede4a8da4 getarch now compiles and sets config.h defines properly. 
Still isn't parsed into CMake variables, and getarch_2 needs to
get the same treatment.

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.

d2d15e522f Started converting lib target to CMake. 
The main part of this target is looping through the BLAS subfolders
and calling make on them. Need to add CMakeLists.txt for each of these
subfolders.

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.

Fix #478
