| 31 | |
| 32 hacked on by jwz@jwz.org 1991-06 | |
| 33 o added a compile-time switch to turn on simple sanity checking; | |
| 34 o put back the obsolete byte-codes for error-detection; | |
| 35 o added a new instruction, unbind_all, which I will use for | |
| 36 tail-recursion elimination; | |
| 37 o made temp_output_buffer_show be called with the right number | |
| 38 of args; | |
| 39 o made the new bytecodes be called with args in the right order; | |
| 40 o added metering support. | |
| 41 | |
| 42 by Hallvard: | |
| 43 o added relative jump instructions; | |
| 44 o all conditionals now only do QUIT if they jump. | |

| 735 loop (21.5.14 and before), but that interferes with collection of weakly | |
| 736 referenced objects. Although strictly speaking there's no promise that | |
| 737 weak references will disappear by any given point in time, they should | |
| 738 be collected at the first opportunity. Waiting until exit from the | |
| 739 function caused test failures because "stale" objects "above" the top of | |
| 740 the stack were still GCPROed, and they were not getting collected until | |
| 741 after exit from the (byte-compiled) test! | |
| 742 | |
| 743 Now the idea is to dynamically adjust the array of GCPROed objects to | |
| 744 include only the "active" region of the stack. | |
| 745 | |
| 746 We use the "GCPRO1 the array base and set the nvars member" method. It | |
| 747 would be slightly inefficient but correct to use GCPRO1_ARRAY here. It | |
| 748 would just redundantly set nvars. | |
| 749 #### Maybe it would be clearer to use GCPRO1_ARRAY and do GCPRO_STACK | |
| 750 after the switch? | |
| 751 | |
| 752 GCPRO_STACK is something of a misnomer, because it suggests that a | |
| 753 struct gcpro is initialized each time. This is false; only the nvars | |
| 754 member of a single struct gcpro is being adjusted. This works because | |
| 755 each time a new object is assigned to a stack location, the old object | |
| 756 loses its reference and is effectively UNGCPROed, and the new object is | |
| 757 automatically GCPROed as long as nvars is correct. Only when we | |
| 758 return from the interpreter do we need to finalize the struct gcpro | |
| 759 itself, and that's done at case Breturn. | |
