*	x86/emulator: workaround for AMD erratum 573	Jan Beulich	2011-12-16	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The only cases where we might end up emulating fsincos (as any other x87 operations without memory operands) are - when a HVM guest is in real mode (not applicable on AMD) - between two half page table updates in PAE mode (unlikely, and not doing the emulation here does affect only performance, not correctness) - when a guest maliciously (or erroneously) modifies an (MMIO or page table update) instruction under emulation (unspecified behavior) Hence, in order to avoid the erratum to cause harm to the entire host, don't emulate fsincos on the affected AMD CPU families.

*	x86/emulator: add emulation of SIMD FP moves	Jan Beulich	2011-12-01	1	-0/+54
\| \| \| \| \| \| \| \| \| \|	Clone the existing movq emulation to also support the most fundamental SIMD FP moves. Extend the testing code to also exercise these instructions. Signed-off-by: Jan Beulich <jbeulich@suse.com> Acked-by: Keir Fraser <keir@xen.org>
*	x86/emulator: generalize movq emulation (SSE2 and AVX variants)	Jan Beulich	2011-12-01	1	-0/+187
\| \| \| \| \| \| \| \| \| \| \| \|	Extend the existing movq emulation to also support its SSE2 and AVX variants, the latter implying the addition of VEX decoding. Fold the read and write cases (as most of the logic is identical), and add movntq and variants (as they're very similar). Extend the testing code to also exercise these instructions.

*	x86-64/test_x86_emulate: fix blowfish test	Jan Beulich	2011-11-16	1	-1/+1
\| \| \| \| \| \| \| \|	Incorrect register usage in the _start() wrapper caused the 64-bit execution emulation to fail. Signed-off-by: Jan Beulich <jbeulich@suse.com> Committed-by: Keir Fraser <keir@xen.org>
*	build: Make XEN_ROOT an absolute path.	Keir Fraser	2011-03-17	2	-2/+2
\| \| \| \| \| \| \| \|	Otherwise make can search the path relative to certain standard paths such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in Config.mk suffers from this). Signed-off-by: Keir Fraser <keir@xen.org>
