Commit ID 876f07cbeea5b583ca75685cefa0fd4be1e904a4
Author Joost VandeVondele
Date 2016-11-06 10:48:07 UTC
Fix undefined behaviour with unaligned loads in syzygy code Casting a pointer to a different type with stricter alignment requirements yields to implementation dependent behaviour. Practicaly everything is fine for common platforms because the CPU/OS/compiler will generate correct code, but anyhow it is better to be safe than sorry. Testing with dbg_hit_on() shows that the unalignment accesses are very rare (below 0.1%) so it makes sense to split the code in a fast path for the common case and a slower path as a fallback. No functional change (verified with TB enabled).
