Fish ad7ae63e92 Remove unmapped/freed memory regions from the object property list. This commit fixes the following issues: - Any unmapped/free'd memory regions (MemoryRegion instances) are not removed from the object property linked list of its owner (which is always qdev_get_machine(uc)). This issue makes adding new memory mapping by calling mem_map() or mem_map_ptr() slower as more and more memory pages are mapped and unmapped - yes, even if those memory pages are unmapped, they still impact the speed of future memory page mappings due to this issue. - FlatView is not reconstructed after a memory region is freed during unmapping, which leads to a use-after-free the next time a new memory region is mapped in address_space_update_topology().		2016-10-20 03:48:58 -07:00

Clean/simple/lightweight/intuitive architecture-neutral API
Implemented in pure C language, with bindings for Perl, Rust, Ruby, Python, Java, MSVC, .NET, Go, Delphi/Free Pascal and Haskell.
Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
High performance via Just-In-Time compilation
Support for fine-grained instrumentation at various levels
Thread-safety by design
Distributed under free software license GPLv2
