Craig Donner	ba586c3d16	Ensure that the gotoblas lookup table is always initialized. It is possible to build a program that calls a non-GEMM OpenBLAS routine from a static initializer. Since the order of initialization is undefined, and even less defined when using __attribute__((constructor)) in one TU and a C++ static initializer in another TU, it can happen (and does, unfortunately) that gotoblas_init is not called before the first BLAS routine. This results in a segfault when trying to index into the gotoblas table. The solution I have here is indirection: rather than directly using the table use an inlined function to first check if it's been initialized. Since it will only not have been done once, hopefully the branch prediction still keeps things fast.	7 years ago
Martin Koehler	711ca33bc6	Improved Ximatcopy when lda==ldb. The Ximatcopy functions create a copy of the input matrix although they seem to work inplace. The new routines XIMATCOPY_K_YY perform the operations inplace if the leading dimension does not change.	10 years ago
