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

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

  data struct) to help differentiate

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
