|
32 o added a compile-time switch to turn on simple sanity checking;
|
|
|
33 o put back the obsolete byte-codes for error-detection;
|
|
173
|
34 o added a new instruction, unbind_all, which I will use for
|
|
0
|
35 tail-recursion elimination;
|
|
|
36 o made temp_output_buffer_show be called with the right number
|
|
|
37 of args;
|
|
|
38 o made the new bytecodes be called with args in the right order;
|
|
|
39 o added metering support.
|
|
|
40
|
|
|
41 by Hallvard:
|
|
|
42 o added relative jump instructions;
|
|
|
43 o all conditionals now only do QUIT if they jump.
