GSoC 2015

[Prateek Gupta]

As far as I percieve, the multiarchitecture support project is about making
a hierarchial set of the parsers to firstly compiling all general parser
required by every arch and then compiling only those that are required by
the arch that the user's system has.

My approach for the problem is to develop a cpu_config.h like header file
whose work would be to detect the set of features supported by the CPU by
hooking up a tool RPM (RedHat Packet Manager) for platform detection. Then
we can integrate this information with the build process by creating a
hierarchy of the parsers as universal and arch specific by code changes.

Need inputs on this idea..Hoping for a reply!

Prateek Gupta
