The `clz` instruction pretty much implements getting the most significant bit in hardware, so use it instead of the software implementation. This reults in both a reduction in code size as in a speedup: master: text data bss dec hex filename 14816 136 2424 17376 43e0 tests/bitarithm_timings/bin/same54-xpro/tests_bitarithm_timings.elf + bitarithm_msb: 3529411 iterations per second this patch: text data bss dec hex filename 14768 136 2424 17328 43b0 tests/bitarithm_timings/bin/same54-xpro/tests_bitarithm_timings.elf + bitarithm_msb: 9230761 iterations per second |
