| 28 | /* This module provides the function mdebug_build_psymtabs. It reads |
| 29 | ECOFF debugging information into partial symbol tables. The |
| 30 | debugging information is read from two structures. A struct |
| 31 | ecoff_debug_swap includes the sizes of each ECOFF structure and |
| 32 | swapping routines; these are fixed for a particular target. A |
| 33 | struct ecoff_debug_info points to the debugging information for a |
| 34 | particular object file. |
| 35 | |
| 36 | ECOFF symbol tables are mostly written in the byte order of the |
| 37 | target machine. However, one section of the table (the auxiliary |
| 38 | symbol information) is written in the host byte order. There is a |
| 39 | bit in the other symbol info which describes which host byte order |
| 40 | was used. ECOFF thereby takes the trophy from Intel `b.out' for |
| 41 | the most brain-dead adaptation of a file format to byte order. |
| 42 | |
| 43 | This module can read all four of the known byte-order combinations, |
| 44 | on any type of host. */ |

| 999 | addition of the stStruct, stUnion, and stEnum symbol |
| 1000 | types.) The way you can tell is if/when you see a variable |
| 1001 | or field of that type. In that case the variable's type |
| 1002 | (in the AUX table) says if the type is struct, union, or |
| 1003 | enum, and points back to the stBlock here. So you can |
| 1004 | patch the tag kind up later - but only if there actually is |
| 1005 | a variable or field of that type. |
| 1006 | |
| 1007 | So until we know for sure, we will guess at this point. |
| 1008 | The heuristic is: |
| 1009 | If the first member has index==indexNil or a void type, |
| 1010 | assume we have an enumeration. |
| 1011 | Otherwise, if there is more than one member, and all |
| 1012 | the members have offset 0, assume we have a union. |
| 1013 | Otherwise, assume we have a struct. |
| 1014 | |
| 1015 | The heuristic could guess wrong in the case of of an |
| 1016 | enumeration with no members or a union with one (or zero) |
| 1017 | members, or when all except the last field of a struct have |
| 1018 | width zero. These are uncommon and/or illegal situations, |
| 1019 | and in any case guessing wrong probably doesn't matter |
| 1020 | much. |
| 1021 | |
| 1022 | But if we later do find out we were wrong, we fixup the tag |
| 1023 | kind. Members of an enumeration must be handled |
| 1024 | differently from struct/union fields, and that is harder to |
| 1025 | patch up, but luckily we shouldn't need to. (If there are |

| 2337 | |
| 2338 | For ECOFF in ELF, we skip the creation of the minimal symbols. |

| 2340 | section information of the elf symbols will be more accurate. |
| 2341 | FIXME! What about Irix 5's native linker? |
| 2342 | |
| 2343 | By default, Elf sections which don't exist in ECOFF |
| 2344 | get put in ECOFF's absolute section by the gnu linker. |
| 2345 | Since absolute sections don't get relocated, we |
| 2346 | end up calculating an address different from that of |
| 2347 | the symbol's minimal symbol (created earlier from the |
| 2348 | Elf symtab). |
| 2349 | |
| 2350 | To fix this, either : |
| 2351 | 1) don't create the duplicate symbol |
| 2352 | (assumes ECOFF symtab is a subset of the ELF symtab; |
| 2353 | assumes no side-effects result from ignoring ECOFF symbol) |
| 2354 | 2) create it, only if lookup for existing symbol in ELF's minimal |
| 2355 | symbols fails |
| 2356 | (inefficient; |
| 2357 | assumes no side-effects result from ignoring ECOFF symbol) |
| 2358 | 3) create it, but lookup ELF's minimal symbol and use it's section |
| 2359 | during relocation, then modify "uniqify" phase to merge and |
| 2360 | eliminate the duplicate symbol |
| 2361 | (highly inefficient) |
| 2362 | |
