As suggested by Paolo:
That part of tcg/tcg-runtime.c probably should be moved to user-exec.c,
and user-exec.c should in turn be in accel/tcg.
in http://lists.nongnu.org/archive/html/qemu-devel/2017-07/msg03657.html
also update MAINTAINERS accordingly.
Regards,
Phil.
Philippe Mathieu-Daudé (4):
tcg: move user-exec
tcg: move tcg-runtime to accel/tcg/
tcg: move atomic_template.h to accel/tcg/
tcg: restrict i386 regs definitions

The header is only used by accel/tcg/cputlb.c so we can
move it to the accel/tcg/ folder, too.

Why to move under i386?
SmartOS pollutes namespace with these symbols on x86_64.

To make this better, the "#ifndef CONFIG_SOFTMMU" part at the
end of this should be moved to user-exec.c. Feel free to just
post a sixth patch for it.

> Why to move under i386?
I tracked the origin of these #defines in op-i386.c (7bfdb6d18c7b) and
thought the Exx naming was for i386 while the x86_64 uses the Rxx naming
(RAX .. RIP) so you'd only have them on i386 arch.
However it seems I didn't realize you can access x86_64 registers in
32-bit mode via the EAX .. EIP naming, as you see I'm not confident with
this CISC arch :S
So I guess it's best to ignore this patch?
