If you wish to withdraw\nyour ack, please let me know but I believe the 2 additions are consistent\nwith previous.\n\nv8:\n * squish patch including rte_bitops.h in lib/pipeline into\n first patch.\n\nv7:\n * add 2 additional counting functions rte_popcount{32,64}\n including basic unit tests\n * fix patch 1 title link (CI complained too long)\n * add test_bitcount.c entry to MAINTAINERS file\n\nv6:\n * remove stray #include <stdio.h>\n\nv5:\n * fix implementation of msvc versions of rte_clz{32,64}\n incorrect use of _BitscanReverse{,64} index.\n * fix and expand unit test to exercise full range of counting\n over uint{32,64}_t input values. (which would have caught\n above mistake).\n * reduce commit title length\n * correct commit author\n\nv4:\n * combine unit test commit into function addition commit\n\nv3:\n * rename to use 32/64 instead of l/ll suffixes\n * add new functions to rte_bitops.h instead of new header\n * move other bit functions from rte_common.h to rte_bitops.h\n\nv2:\n * use unsigned int instead of unsigned (checkpatches)\n * match multiple include guard naming convention to rte_common.h\n * add explicit extern \"C\" linkage to rte_bitcount.h\n note: not really needed but checkpatches required\n * add missing space around '-'\n\nTyler Retzlaff (3):\n eal: move bit count functions to bitops header\n eal: provide abstracted bit count functions\n maintainers: add bitcount test under EAL API and common code\n\n MAINTAINERS | 1 +\n app/test/meson.build | 2 +\n app/test/test_bitcount.c | 136 ++++++++\n app/test/test_common.c | 1 +\n lib/eal/common/rte_reciprocal.c | 1 +\n lib/eal/include/rte_bitops.h | 532 +++++++++++++++++++++++++++++++\n lib/eal/include/rte_common.h | 293 -----------------\n lib/pipeline/rte_swx_pipeline_internal.h | 1 +\n 8 files changed, 674 insertions(+), 293 deletions(-)\n create mode 100644 app/test/test_bitcount.c" }
