Ticket #310 – Description
initial v6 2 2 3 3 Details:: 4 The DWARF Debugging Information Format is a rich, processor architecture independent debugging format supported by the toolchain used to build HelenOS. It encodes information that may otherwise be hard or impossible to get during HelenOS run-time. The goal of this project is to identify aspects of the DWARF format that would improve the debugging capabilities and observability of both the HelenOS kernel and applications, and bring support for those aspects to HelenOS. An example of such an aspect is the support for reliable call stack unwinding.4 The DWARF Debugging Information Format is a rich, processor architecture independent debugging format supported by the toolchain used to build HelenOS.
