Knowledge about each performed memory allocation enables the following: + +- Memory usage graph (like in massif, but fully interactable). +- List of active allocations at program exit (leak list). +- Visualization of memory map. +- Ability to rewind view of active allocations and memory map to any point of program execution. +- Information about memory statistics of each zone. + +To mark memory events, use the `TracyAlloc( ptr, size )` and `TracyFree( ptr )` macros. Typically you would do that in overloads of `operator new` and `operator delete`. + #### Lua support To profile Lua code using tracy, include the `tracy/TracyLua.hpp` header file in your Lua wrapper and execute `tracy::LuaRegister( lua_State* )` function to add instrumentation support. In your Lua code, add `tracy.ZoneBegin()` and `tracy.ZoneEnd()` calls to mark execution zones. Double check if you have included all return paths! Use `tracy.ZoneBeginN( name )` to set zone name. Use `tracy.ZoneText( text )` to set zone text. Use `tracy.Message( text )` to send messages.
