Details: - Replaced all instances of bli_malloc() and bli_free() with one of: - bli_malloc_pool()/bli_free_pool() - bli_malloc_user()/bli_free_user() - bli_malloc_intl()/bli_free_intl() each of which can be configured to call malloc()/free() substitutes, so long as the substitute functions have the same function type signatures as malloc() and free() defined by C's stdlib.h. The _pool() function is called when allocating blocks for the memory pools (used for packing buffers, primarily), the _user() function is called when obj_t's are created (via bli_obj_create() and friends), and the _intl() function is called for internal use by BLIS, such as when creating control tree nodes or temporary buffers for manipulating internal data structures. Substitutes for any of the three types of bli_malloc() may be specified by #defining the following pairs of cpp macros in bli_kernel.h: - BLIS_MALLOC_POOL/BLIS_FREE_POOL - BLIS_MALLOC_USER/BLIS_FREE_USER - BLIS_MALLOC_INTL/BLIS_FREE_INTL to be the name of the substitute functions. (Obviously, the object code that contains these functions must be provided at link-time.) These macros default to malloc() and free(). Subsitute functions are also automatically prototyped by BLIS (in bli_malloc_prototypes.h). - Removed definitions for bli_malloc() and bli_free(). - Note that bli_malloc_pool() and bli_malloc_user() are now defined in terms of a new function, bli_malloc_align(), which aligns memory to an arbitrary (power of two) alignment boundary, but does so manually, whereas before alignment was performed behind the scenes by posix_memalign(). Currently, bli_malloc_intl() is defined in terms of bli_malloc_noalign(), which serves as a simple wrapper to the designated function that is passed in (e.g. BLIS_MALLOC_INTL). Similarly, there are bli_free_align() and bli_free_noalign(), which are used in concert with their bli_malloc_*() counterparts.
