# Progress #

* TCWG-333, ISA bit treatment in ARM thumb mode.
Got some comments from Maciej (MIPS) and need to address them.

* TCWG-518, ARM range stepping patches. [2/10]
Combine the path of "proceed" and "resume" so that we only change one
place instead of two to support range stepping. Patches are being
tested.

* TCWG-655, Workaround ARM linux kernel ptrace bug... [2/10]
by pining both program and debugger on the same core in the affected
test cases.

* Off on Wed to Fri. [6/10]
