| 87 of hash tables for all info but that fails in the presence of | |
| 88 recursive functions because they can modify values out from under | |
| 89 you. The algorithm here is that we record the total_ticks and | |
| 90 total_consing, as well as the current values of `total-timing' and | |
| 91 `total-gc-usage' for the OBJ -- that's because recursive functions, | |
| 92 which get called later and exit early, will go ahead and modify the | |
| 93 `total-timing' and `total-gc-usage' for the fun, even though it's | |
| 94 not "correct" because the outer function is still running. However, | |
| 95 if we ask for profiling info at this point, at least we're getting | |
| 96 SOME info. | |
| 97 | |
| 98 So ... On entry, we record these four values. On exit, we compute | |
| 99 an offset from the recorded value to the current value and then | |
| 100 store it into the appropriate hash table entry, using the recorded | |
| 101 value in the entry rather than the actual one. (Inner recursive | |
| 102 functions may have added their own values to the total-counts, and | |
| 103 we want to subsume them, not add to them.) | |

| 853 | 116 (No information is stored concerning how to restore the state of |
| 117 the condition-handler list; this is handled implicitly through | |
| 118 an unwind-protect. unwind-protects are on the specbind stack, | |
| 119 which is reset to its proper value by `throw'. In the process of | |
| 120 that, any intervening bindings are reset and unwind-protects called, | |
| 121 which fixes up the condition-handler list. | |
| 428 | 122 |
| 123 catchtag structures are chained together in the C calling stack; | |
| 124 the `next' member points to the next outer catchtag. | |
| 125 | |
| 126 A call like (throw TAG VAL) searches for a catchtag whose `tag' | |
| 853 | 127 member is TAG, and then unbinds to it. A value of Vcatch_everything_tag |
| 128 for the `tag' member of a catchtag is special and means "catch all throws, | |
| 129 regardless of the tag". This is used internally by the C code. The `val' | |
| 130 member is used to hold VAL while the stack is unwound; `val' is returned | |
| 131 as the value of the catch form. The `actual_tag' member holds the value | |
| 132 of TAG as passed to throw, so that it can be retrieved when catches with | |
| 133 Vcatch_everything_tag are set up. | |
