Logs
To enable various logs, modify the defines in m3_config.h. These are only enabled when compiled in debug mode.
# define d_m3LogParse 0 // .wasm binary decoding info
# define d_m3LogModule 0 // Wasm module info
# define d_m3LogCompile 0 // wasm -> metacode generation phase
# define d_m3LogWasmStack 0 // dump the wasm stack when pushed or popped
# define d_m3LogEmit 0 // metacode-generation info
# define d_m3LogCodePages 0 // dump metacode pages when released
# define d_m3LogRuntime 0 // higher-level runtime information
# define d_m3LogNativeStack 0 // track the memory usage of the C-stack
Operation Profiling
To profile the interpreter's operations enable d_m3EnableOpProfiling in m3_config.h. This profiling option works in either release or debug builds.
When a runtime is released or m3_PrintProfilerInfo () is called, a table of the executed operations and
their instance counts will be printed to stderr.
