src/tests/lib/libnvmm: h_mem_assist.c h_mem_assist_asm.S
Log Message:
Improvements:
- Emulate the instructions by executing them directly on the host CPU.
This is easier and probably faster than doing it in software
manually.
- Decode SUB from Primary, CMP from Group1, TEST from Group3, and add
associated tests.
- Handle correctly the cases where an instruction that always implicitly
reads the register operand is executed with the mem operand as source
(eg: "orq (%rbx),%rax").
- Fix the MMU handling of 32bit-PAE. Under PAE CR3 is not page-aligned,
so there are extra bits that are valid.
With these changes in place I can boot Windows XP on Qemu+NVMM.
