| /* TODO |
| * - support for symbols' types is still partly missing |
| * + C++ support |
| * + we should store the underlying type for an enum in the symt_enum struct |
| * + for enums, we store the names & values (associated to the enum type), |
| * but those values are not directly usable from a debugger (that's why, I |
| * assume, that we have also to define constants for enum values, as |
| * Codeview does BTW. |
| * + SymEnumTypes should only return *user* defined types (UDT, typedefs...) not |
| * all the types stored/used in the modules (like char*) |
| * - SymGetLine{Next|Prev} don't work as expected (they don't seem to work across |
| * functions, and even across function blocks...). Basically, for *Next* to work |
| * it requires an address after the prolog of the func (the base address of the |
| * func doesn't work) |
| * - most options (dbghelp_options) are not used (loading lines...) |
| * - in symbol lookup by name, we don't use RE everywhere we should. Moreover, when |
| * we're supposed to use RE, it doesn't make use of our hash tables. Therefore, |
| * we could use hash if name isn't a RE, and fall back to a full search when we |
| * get a full RE |
| * - msc: |
| * + we should add parameters' types to the function's signature |
| * while processing a function's parameters |
| * + add support for function-less labels (as MSC seems to define them) |
| * + C++ management |
| * - stabs: |
| * + when, in a same module, the same definition is used in several compilation |
| * units, we get several definitions of the same object (especially |
| * struct/union). we should find a way not to duplicate them |
| * + in some cases (dlls/user/dialog16.c DIALOG_GetControl16), the same static |
| * global variable is defined several times (at different scopes). We are |
| * getting several of those while looking for a unique symbol. Part of the |
| * issue is that we don't give a scope to a static variable inside a function |
| * + C++ management |

| * Since, we're also allow to load ELF (pure) libraries and Wine ELF libraries |
| * containing PE (and NE) module(s), here's how we handle it: |
| * - we load every module (ELF, NE, PE) passed in SymLoadModule |
| * - in fInvadeProcess (in SymInitialize) is TRUE, we set up what is called ELF |

| * our internal ELF modules representation (loading / unloading). This way, |
| * we'll pair every loaded builtin PE module with its ELF counterpart (and |
| * access its debug information). |
| * - if fInvadeProcess (in SymInitialize) is FALSE, we check anyway if the |
| * hProcess refers to a running process. We use some heuristics here, so YMMV. |
| * If we detect a live target, then we get the same handling as if |
| * fInvadeProcess is TRUE (except that the modules are not loaded). Otherwise, |
| * we won't be able to make the peering between a builtin PE module and its ELF |
| * counterpart. Hence we won't be able to provide the requested debug |
| * information. We'll however be able to load native PE modules (and their |
| * debug information) without any trouble. |
| * Note also that this scheme can be intertwined with the deferred loading |
| * mechanism (ie only load the debug information when we actually need it). |
