Jojo R	12b8d542b7	norm.cpp(normL2Sqr_): improve performance of pipeline The most of target machine use one type cpu unit resource to execute some one type of instruction, e.g. all vx_load API use load/store cpu unit, and v_muladd API use mul/mula cpu unit, we interleave vx_load and v_muladd to improve performance on most targets like RISCV or ARM.	4 years ago

Vadim Pisarevsky	2ee9d21dae	Merge pull request #18571 from vpisarev:add_lapack Added clapack * bring a small subset of Lapack, automatically converted to C, into OpenCV * added missing lsame_ prototype * * small fix in make_clapack script * trying to fix remaining CI problems * fixed character arrays' initializers * get rid of F2C_STR_MAX * * added back single-precision versions for QR, LU and Cholesky decompositions. It adds very little extra overhead. * added stub version of sdesdd. * uncommented calls to all the single-precision Lapack functions from opencv/core/src/hal_internal.cpp. * fixed warning from Visual Studio + cleaned f2c runtime a bit * * regenerated Lapack w/o forward declarations of intrinsic functions (such as sqrt(), r_cnjg() etc.) * at once, trailing whitespaces are removed from the generated sources, just in case * since there is no declarations of intrinsic functions anymore, we could turn some of them into inline functions * trying to eliminate the crash on ARM * fixed API and semantics of s_copy * * CLapack has been tested successfully. It's now time to restore the standard LAPACK detection procedure * removed some more trailing whitespaces * * retained only the essential stuff in CLapack * added checks to lapack calls to gracefully return "not implemented" instead of returning invalid results with "ok" status * disabled warning when building lapack * cmake: update LAPACK detection Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>	4 years ago
