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.
