Subject: [PATCH 7/7] Reduce memory waste due to non-power-of-2 allocs
2011/9/17 Dodji Seketeli do...@redhat.com:
OK, so the patch below extracts a public ggc_alloced_size_for_request
function from the different implementations of the ggc allocator's
interface, and lets new_linemap use that.

memory allocator. That is, I'd like to see the memory allocator have
an interface that returns the actual size of memory it has allocated.
This would help client code like this
