I am using qemu to run VMs on my computer with amd chip on board.
However, my computer doesn't support amd-v, so the performance of the VM is
low.
I do have experiences in optimization of program using sse technique.
Is it possible to speed up the qemu for those x86 chips that do not support

In this rebased version I pushed the exception helper conversion first.
Helpers for cpu_{ld,st}_data are in common code.
Two new bonus patches last.

to Blue-Avi-Blue.
Inlining memory_region_section_addr is a bit premature, but doesn't
really matter. My feeling is that we should turn on LTO
Fold is_ram_rom and is_ram_rom_romd() into callers.
Change is_romd() and section_addr() to take MemoryRegion

For Linux to be able to work out how fast its clocks are going, so
that timer ticks come approximately at the right time, it needs to
be able to query the clock control module (CCM).
This is the start of a CCM implementation. It currently knows only about
