Commit Message

James Greenhalgh Sept. 6, 2013, 1:24 p.m. UTC 
This patch splits the f_cvt attribute to:

 * f_cvt conversions between float representations.
 * f_cvti2f conversions from int to float.
 * f_cvtf2i conversions from float to int.

Then we update the pipeline descriptions to refelct this change.

Regression tested for aarch64-none-elf and arm-none-eabi and sanity
checked. Bootstrapped in series with other type splitting patches.

OK?

Thanks,
James
