413 | 2. not pxdbed and doc | |

419 | - DEBUG and HEADER sections are there | |
420 | - header is XDB_header type | |
421 | - pxdbed flag is set to 0 | |
422 | ||
423 | NOTE: the pxdbed flag is meaningful also in the not | |
424 | already pxdb processed version of the header, | |
425 | because in case on non-already processed by pxdb files | |
426 | that same bit in the header would be always zero. | |
427 | Why? Because the bit is the leftmost bit of a word | |
428 | which contains a 'length' which is always a positive value | |
429 | so that bit is never set to 1 (otherwise it would be negative) | |
430 | ||
431 | Given the above, we have two choices : either we ignore the | |
432 | size of the header itself and just look at the pxdbed field, | |
433 | or we check the size and then we (for safety and paranoia related | |
434 | issues) check the bit. | |
435 | The first solution is used by DDE, the second by PXDB itself. | |
436 | I am using the second one here, because I already wrote it, | |
437 | and it is the end of a long day. | |
438 | Also, using the first approach would still involve size issues | |
439 | because we need to read in the contents of the header section, and | |

4601 | * example is when we're processing the symbol table record | |
4602 | * for a data symbol (a SVAR or DVAR record). That has | |
4603 | * a "type" field specifying the type of the data symbol. That | |
4604 | * "type" field is either an "immediate" type specification (for the | |
4605 | * fundamental types) or a DNTT pointer (for more complicated types). | |
4606 | * For the more complicated types, we may or may not have already | |
4607 | * processed the pointed-to type. (Multiple data symbols can of course | |
4608 | * share the same type). | |
4609 | * The job of hpread_type_lookup() is to process this "type" field. | |
4610 | * Most of the real work is done in subroutines. Here we interpret | |
4611 | * the immediate flag. If not immediate, chase the DNTT pointer to | |
4612 | * find our way to the SOM record describing the type, switch on | |
4613 | * the SOM kind, and then call an appropriate subroutine depending | |
4614 | * on what kind of type we are constructing. (e.g., an array type, | |
