Support for DWARF Debugging Information Format
Implement support for an essential subset of the DWARF Debugging Information Format in HelenOS.
- Details
-
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.
- What Gains and Benefits will this bring?
-
Besides other possible benefits that depend on the supported features, one key benefit would be the ability to reliably generate stack traces on some architectures that are not stacktracing-friendly, such as mips32.
- Difficulty
-
Medium
- Required skills
-
A successful applicant will have good skills of programming in the C language and at least basic familiarity with binutils, gcc and linker scripts. This project may expose the candidate to mips32 assembly.
