Reading same location from multiple threads is perfectly fine

Depends. The compiler may not be able to determine whether some unrelated write access has aliased to the tables.


this is not a task for the compiler, but for the programmer. if you're obsessed, cache-align your tables (or use dumb padding)

initialized data is usually grouped in a separate section, so unless your tables are generated on the fly, the probability should be literally zero
