Project Name
To Thumb? or Not to Thumb?
Project Description
Fedora-ARM does not use thumb. The purpose of this project is to discover whether thumb provides any significant savings in terms of code size, whether programs compiled to thumb execute more quickly or more slowly than non-thumb programs on common ARM processors, whether a thumb compilation takes more or less time than non-thumb, and whether there are any other factors that would influence the decision to support thumb. Ultimately, this project should make a recommendation on the use of the thumb instruction set for the Fedora-ARM secondary architecture.
Project Leader(s)

What I need to learn
Pretty much everything from the scratch. It seems like this project requires lots of background information such as RISC, CISC, Instruction set, Register set, different versions of ARM architecture versions, armv5tel and newer ( and better) models and etc.
Project Plan
Goals for each release:
- 0.1
- 0.2
- 0.3
