| 30 hacked on by jwz@jwz.org 1991-06 | |
| 31 o added a compile-time switch to turn on simple sanity checking; | |
| 32 o put back the obsolete byte-codes for error-detection; | |
| 33 o added a new instruction, unbind_all, which I will use for | |
| 34 tail-recursion elimination; | |
| 35 o made temp_output_buffer_show be called with the right number | |
| 36 of args; | |
| 37 o made the new bytecodes be called with args in the right order; | |
| 38 o added metering support. | |
| 39 | |
| 40 by Hallvard: | |
| 41 o added relative jump instructions; | |
| 42 o all conditionals now only do QUIT if they jump. | |

| 791 loop (21.5.14 and before), but that interferes with collection of weakly | |
| 792 referenced objects. Although strictly speaking there's no promise that | |
| 793 weak references will disappear by any given point in time, they should | |
| 794 be collected at the first opportunity. Waiting until exit from the | |
| 795 function caused test failures because "stale" objects "above" the top of | |
| 796 the stack were still GCPROed, and they were not getting collected until | |
| 797 after exit from the (byte-compiled) test! | |
| 798 | |
| 799 Now the idea is to dynamically adjust the array of GCPROed objects to | |
| 800 include only the "active" region of the stack. | |
| 801 | |
| 802 We use the "GCPRO1 the array base and set the nvars member" method. It | |
| 803 would be slightly inefficient but correct to use GCPRO1_ARRAY here. It | |
| 804 would just redundantly set nvars. | |
| 805 #### Maybe it would be clearer to use GCPRO1_ARRAY and do GCPRO_STACK | |
| 806 after the switch? | |
| 807 | |
| 808 GCPRO_STACK is something of a misnomer, because it suggests that a | |
| 809 struct gcpro is initialized each time. This is false; only the nvars | |
| 810 member of a single struct gcpro is being adjusted. This works because | |
| 811 each time a new object is assigned to a stack location, the old object | |
| 812 loses its reference and is effectively UNGCPROed, and the new object is | |
| 813 automatically GCPROed as long as nvars is correct. Only when we | |
| 814 return from the interpreter do we need to finalize the struct gcpro | |
| 815 itself, and that's done at case Breturn. | |
