Alexander Alekhin	0595ab3eef	ocl: fix usage of invalid OpenCL cache on mixed 64/32-bit platforms Observed during launch of 32/64-bit applications on Windows. Added '32-bit' prefix for 32-bit OpenCL devices. No prefix on 64-bit configurations.	7 years ago
Sayed Adel	6fe6436162	core:ppc Fixed compilation with xlc, clang. - Use EXPECT_TRUE instead of EXPECT_EQ for comparing NULL in xlc - Added support for int64 to vec_promote in xlc, clang - Fixed v_rotate_right in xlc	7 years ago

Alexander Alekhin	0ed3209b00	ocl: avoid unnecessary loading/initializing OpenCL subsystem If there are no OpenCL/UMat methods calls from application. OpenCL subsystem is initialized: - haveOpenCL() is called from application - useOpenCL() is called from application - access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled (independent from OpenCL linkage type)	7 years ago

Simon Guo	2610a47c89	core:ppc Fix 2 interleave logic errors in vsx_utils.hpp When elements are 64 bits, the vec_st_interleave()/vec_ld_deinterleave() doesn't interleave 4 elements correctly. For vec_st_interleave(), following is saved into mem: a0 b0 a1 b1 c0 d0 c1 d1 -> we expected: a0 b0 c0 d0 a1 b1 c1 d1 for vec_ld_deinterleave(), following is loaded into a b c d for memory string { 1 2 3 4 5 6 7 8 }: a: 1 3 b: 2 4 c: 5 7 d: 6 8 -> we expected: a: 1 5 b: 2 6 c: 3 7 d: 4 8 This patch corrects this behavior.

Sayed Adel	def444d99f	core: Several improvements to Power/VSX - changed behavior of vec_ctf, vec_ctu, vec_cts in gcc and clang to make them compatible with XLC - implemented most of missing conversion intrinsics in gcc and clang - implemented conversions intrinsics of odd-numbered elements - ignored gcc bug warning that caused by -Wunused-but-set-variable in rare cases - replaced right shift with algebraic right shift for signed vectors to shift in the sign bit. - added new universal intrinsics v_matmuladd, v_rotate_left/right - avoid using floating multiply-add in RNG	7 years ago

Mattia Rizzolo	d026d7dcfb	Fix build for non-linux architectures but still glibc-based Exampls of these are gnu/kfreebsd and gnu/hurd, both available as unofficial Debian ports. They don't define __linux__ (as they are non-linux…) but still define __GLIBC__, so check on that. Signed-off-by: Mattia Rizzolo <mattia@mapreri.org>	7 years ago
