Sprints

Whiteboard

Possible items for phase 2:
investigate test suite failures on ARM (and fix them): TODO
Enhance the testsuite: TODO
Enhance DWARF support [4]: TODO

[1] this might be trickier since it touches various pieces in the common code and we don't want to break things on other architectures

[2] simplifies cross compiling, should be easy

[4] this is a lot of work since libunwind currently understands DWARF2 only (if at all)
 - DWARF has evolved a lot (turing complete)
 - does the GCC really use sophisticated DWARF in case of unwinding?
  (computations of optimized values don't apply here)

(?)

Work Items

Work items:
ARM extbl parser - handling of the thumb marker: TODO
DWARF parser - handling of the thumb marker[1]: TODO
Handle (save and restore) floating point registers: TODO
Reduce the use of target specific header files[2]: TODO
