[Qemu-devel] [PATCH 06/13] RFC comment out restore_fpu_state (sparc)


From: riku . voipio
Subject: [Qemu-devel] [PATCH 06/13] RFC comment out restore_fpu_state (sparc)
Date: Wed, 23 Apr 2014 16:11:57 +0300

From: Riku Voipio <address@hidden>

A function never called from anywhere, half-complete code
never finished. ifdef completly out. Alternatively we could
just kick it out as the half-ready code could be digged from
git if needed.
