/* 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

* - we load every module (ELF, NE, PE) passed in SymLoadModule
|
|
* - in fInvadeProcess (in SymInitialize) is TRUE, we set up what is called ELF
|
|
* synchronization: hProcess should be a valid process handle, and we hook
|
|
* ourselves on hProcess's loaded ELF-modules, and keep this list in sync with
|
|
* 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).
