Eric Pouech d600115387 dbghelp: Improve the symbol loader.
When looking for a PDB file, no longer use SymFindFileInPath as it

Eric Pouech ade919c603 dbghelp: Cleanups for module loading (lookups on module name and image name are two different things)
- split up module_find_by_name in two different functions:
  + reused module_find_by_name which looks upon the module name
  + added module_is_already_loaded which looks upon the image name
- cleanup module loading using these functions (removed extra parameter
  to pe_load_module_from_pcs)

constant symbols into account for searches by address.
2006-12-06 11:38:43 +01:00
Eric Pouech a1a879363d dbghelp: Added a field to the hash table to store the number of elements in the hash table.

2006-09-26 11:48:39 +02:00
Eric Pouech e4441d7e6f dbghelp: Module info.
- now internally storing module info as a 64bit module structure
  (the interest in not in the 64 bit side of things, but because
  it allows storing lots of usefull information)
- fixed SymGetModuleInfo64W which wasn't returning the
  LoadedPdbName field
- now filling for MSC files with the extended information
  (instead of guessing it)
- reused the extended module info to store wine ELF module
  information (link for map link, stabs vs dwarf symbol info)
2006-06-27 11:17:34 +02:00
Eric Pouech e9910fee66 dbghelp: Dwarf & thunks.
- added the elf_is_in_thunk_area() function to locate an address
  within the known thunk area of Wine's builtin modules
- now passing this thunk information to the dwarf parser so that it
  can drop functions from the thunk areas (as dwarf symbols), so that
  those functions can be later on marked as thunks in dbghelp
  internals
2006-06-26 13:38:03 +02:00

Eric Pouech a49adbc49e dbghelp: Base and symbols.
- report the correct image base for a symbol which is
  seen as being in a builtin PE module, whilst its debug 
  information is gotten from an ELF module
- module_get_debug now returns a pair of modules
  (the requested that has to be presented back to the client
   and the effective one, which contains the debug info)
- reworked SymFromName in order to provide also the revelant
  module base address
2006-05-08 14:47:56 +02:00
