Authored by LukeCheeseman on Dec 17 2018, 9:47 AM.


  • Reapply changes intially introduced in r343089
  • The archtecture info is no longer loaded whenever a DWARFContext is created
  • The runtimes libraries (santiziers) make use of the dwarf context classes but do not intialise the target info
  • The architecture of the object can be obtained without loading the target info
  • Adding a method to the dwarf context to get this information and multiplex the string printing later on
