The int128 implementation of simde_mm_testz_si128() is incorrect, caught in vectoscan CI with SIMDe backend: https://buildbot-ci.vectorcamp.gr/#/builders/119/builds/14 After investigation I found that for x86 the int128 implementation was used and only these tests were failing. The othe...
Hi, I would like to ask how much improvement I can get by replacing _mm_loadu_si128 by _mm_lddqu_si128 on a 64-bit machine. I wrote a simple program
