## Logs
|
||
|
|
|
||
|
|
To enable various logs, modify the defines in `m3_config.h`. These are only enabled when compiled in debug mode.
|
||
|
|
|
||
|
|
```C
|
||
|
|
# 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.
