ASan should support purgeable allocations on Mac #140

Closed ramosian-glider closed 9 years ago

ramosian-glider commented 9 years ago

Originally reported on Google Code with ID 139

For big allocations (at least several pages) allocated from malloc_default_purgeable_zone()
or made such via malloc_make_purgeable() ASan should mark the memory pages as purgeable
to prevent the kernel from swapping them (as requested by the user)
Because in this case any ASan data stored in those pages will be lost, we must not
store headers or stack traces in them.

Why should we bother?
