From src/bytecode.c:
#ifdef BYTE_CODE_METER
DEFVAR_LISP ("byte-code-meter", &Vbyte_code_meter,...
...
#endif
In the comments in the same file:
define BYTE_CODE_METER to enable generation of a byte-op usage
histogram.
So if you are interested, why not define it, re-build and see what
happens?
I have no idea what it does, but since it is not on by default since
1991, and is not documented anywhere, I don't see it as a bug if it
doesn't do whatever it is supposed to do. At the worst it is dead code
that could be deleted.
