[Qemu-devel] [PATCH 3/6] ARM: linux-user: Expose VFP registers to signal handlers

2010-11-24 Thread Peter Maydell
For ARM linux-user mode signal handlers, fill in the ucontext with VFP register contents in the same way that the kernel does. We only do this for v2 format sigframe (2.6.12 and above); this is actually bug-for-bug compatible with the older kernels, which don't save and restore VFP registers either
