== Project Description ==
Many Fedora packages contain assembley code for performance optimization or platform-specific support. Assembley code is very processor-specific. When assembley code is not present for a specific architecture, either the package will not build on that architecture, or other code (typically C) which is not processor-specific is used instead.

This project involves analyzing Fedora packages to determine which ones contain assembly code, and determining whether the package will probably build on the upcoming ARMv8 64-bit architecture.

Expected outcome: An analysis of part of the Fedora package set to predict ARMv8 build outcomes.

Maximum number of students: 6 (each taking part of the Fedora package set)

Skills required: packaging, scripting, writing

Resources: Chris Tyler (ctyler), Jon Masters (jonmasters)

== Project Plan ==

Tracking mechanism (bugzilla, trac, github, ...):

Key contacts:
<!-- Add links to any mentors or key participants in the community. -->

Goals for each release and plans for reaching those goals:
<!-- Note: each contributor is expected to have unique goals. These goals may be ''related'' to other students' work, but must be ''distinct'' and ''attainable'' regardless of the state of the other students' work. For example, under the umbrella of one project title, one student may work on packaging a piece of software and another may work on documentation, or one may work on solving one bug and another on solving another bug, but two students must not work on the same bug or depend on the other students' work in order to be able to complete their own project. -->
* 0.1
** Build initial script to identify assembly code inside fedora packages
** Make a basic database with the initial data
* 0.2
** Generate script that will distinguish between Arch and Platform specific assembly code
** Get/make koji connector to get additional data
** Make a better databse with the newer set dataset
* 0.3
** Predict the list of Fedora packages that may or may not build on ARMv8
