9fb341a9f8 set parameters for CORE_ATHLON 
else dgemm_p is set to zero leading to a segfault in alloc_mmap due to
allocsize being zero

97f68f7f3a Merge pull request #169 from juliantaylor/sanity-check-cpu 
add a sanity check on the detected cpu type
 2012-12-15 06:46:48 -08:00
Julian Taylor
1138817dd2 add a sanity check on the detected cpu type 
if we have 64 bit pointers we can't have a 32 bit cpu, so fall back to
the 64bit cpu fallback (prescott)
E.g. the cpu detection fails in amd qemu64 emulation (family 6 model 2)
causing it to use the uninitialized gotoblas_ATHLON

bdf8d9411e Refs #163. Obtain the build configure on runtime. 
openblas_get_config function returns the configure string.
So far, it supports USE64BITINT, NO_CBLAS, NO_LAPACK, NO_LAPACKE,
DYNAMIC_ARCH, NO_AFFINITY.

Example:
 #include <stdio.h>
extern char * openblas_get_config();
void main()
{
  printf("%s\n",openblas_get_config());
  return;
}

5f0117385e Refs #154. Fixed a SEGFAULT bug of dgemv_t when m is very large. 
It overflowed the internal buffer. Thus, we split vector x into blocks when m is very large.

Thank @wangqian for this patch.

aggregate structures larger than 8 bytes.
