[Valgrind-users] Massif and VALGRIND_MEMPOOL_ALLOC/FREE

[Milian W. <ma...@mi...>]

Hey all,

what do you think about handling VALGRIND_MEMPOOL_ALLOC/FREE like normal 
allocations in massif? This works nicely for pool allocators that use mmap 
directly, instead of using malloc. For pools that use malloc, it will break as 
it will then in the worst-case report the duplicate memory consumption (once 
the block allocation, then all individual allocations in that block).

Still, I think that would be a good idea to have, at least optionally with an 
off-by-default cli switch. I have it tested locally, it is trivial to patch 
Valgrind's massif to do that and I'd be happy to spent more time on making it 
configurable if there's interest.

What do you think?
