| | | | | * added FLLMTag which can be used to register memory tags outside of core * changed `UE_MEMSCOPE` -> `ZEN_MEMSCOPE` for consistency * instrumented some subsystems with dynamic tags
* Insights-compatible memory tracking (#214)Stefan Boberg2024-11-251-0/+1
| | | | | | | | | | | | | This change introduces support for tracing of memory allocation activity. The code is ported from UE5, and Unreal Insights can be used to analyze the output. This is currently only fully supported on Windows, but will be extended to Mac/Linux in the near future. To activate full memory tracking, pass `--trace=memory` on the commandline alongside `--tracehost=<ip>` or `-tracefile=<path>`. For more control over how much detail is traced you can instead pass some combination of `callstack`, `memtag`, `memalloc` instead. In practice, `--trace=memory` is an alias for `--trace=callstack,memtag,memalloc`). For convenience we also support `--trace=memory_light` which omits call stacks. This change also introduces multiple memory allocators, which may be selected via command-line option `--malloc=<allocator>`: * `mimalloc` - mimalloc (default, same as before) * `rpmalloc` - rpmalloc is another high performance allocator for multithreaded applications which may be a better option than mimalloc (to be evaluated). Due to toolchain limitations this is currently only supported on Windows. * `stomp` - an allocator intended to be used during development/debugging to help track down memory issues such as use-after-free or out-of-bounds access. Currently only supported on Windows. * `ansi` - fallback to default system allocator
