63639d44 | 21 | hacked on by jwz@lucid.com 17-jun-91 |
36f7ba0a JB |
22 | o added a compile-time switch to turn on simple sanity checking; |
23 | o put back the obsolete byte-codes for error-detection; | |
8e11578b | 24 | o added a new instruction, unbind_all, which I will use for |
36f7ba0a | 25 | tail-recursion elimination; |
63639d44 | 26 | o made temp_output_buffer_show be called with the right number |
36f7ba0a JB |
27 | of args; |
28 | o made the new bytecodes be called with args in the right order; | |
29 | o added metering support. | |
30 | ||
31 | by Hallvard: | |
3ffbe76b | 32 | o added relative jump instructions; |
36f7ba0a JB |
33 | o all conditionals now only do QUIT if they jump. |
