Peter Oberndorfer debcf7fa32 dbghelp: Use elf load_offset passed to dwarf2_parse to relocate addresses.

Eric Pouech 75033503e8 dbghelp: Added ability to internal store / reload a symbol with a constant value.
Let dwarf and msc use this new feature.
As we also add global symbol without addresses, don't take those
constant symbols into account for searches by address.
2006-12-06 11:38:43 +01:00

2006-11-27 17:58:44 +01:00
Eric Pouech 31f4f1b003 dbghelp: Properly handle the void type in some declarations. 2006-11-27 17:58:22 +01:00

2006-11-27 17:58:11 +01:00
Eric Pouech 305621d5cf dbghelp: Extend support for inlined functions and handle them as generic blocks inside functions
(except for parameters which are converted into local variables).

Rewrote dwarf2_find_attribute so that it takes into account the
abstract origin information when available.

A+
2006-11-27 17:57:54 +01:00
Eric Pouech 497b2e4ea5 dbghelp: Be a bit more strict on where we do actually expect default names to be generated

Eric Pouech e48a46b2b5 dbghelp: Add ability to add a SymTagCustom element to a function.
Make use of it to store the frame information for a dwarf function
(either because frame's location is a location list, or because one of
the function's variables is not properly computed at parse time).
2006-11-27 17:56:17 +01:00
Eric Pouech 0d942b3aaa dbghelp: Function points location is now expressed as a struct location. 2006-11-27 17:55:44 +01:00
Eric Pouech d812f8b42c dbghelp: Added infrastructure to compute variable location at runtime (as opposed to debug info parse time).
Use it to send the variables depending on not known frame register at parse time.
Made just a stub for the location computation function for dwarf2.
2006-11-27 17:55:17 +01:00

Eric Pouech 6c4c64265d dbghelp: Variables & registers.
- more strickling differentiation variable location between 
  a register, and the dereferenced address defined by a
  register (and possibly an offset)

  data struct) to help differentiate
- fix all debug parsers to confer to this new scheme
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

traversing the data.
2006-06-20 11:54:17 +02:00
