From eb987d3a09f669787014b1553f032219522149e1 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Thu, 3 May 2018 08:26:39 -0400 Subject: Harmonize vec/pool_get_aligned object sizes and alignment requests Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.
