Secondly, if I follow your sentences correctly, we might be able to
introduce
AssemblerEmittingMode for X64 assembler instruction, for example,
enum AssemblerEmittingMode {
ARCHITECTURE_DEPENDENT,
ALWAYS_64_BIT,
ALWAYS_32_BIT
}
and introduce move instruction with a default mode as
ARCHITECTURE_DEPENDENT.
It
will address most of the movq usage in the X64 code. When we have to use
64-bit
or 32-bit, we use ALWAYS_64_BIT or ALWAYS_32_BIT. What do you think?
Please ignore this part. We could use template to distinguish movl, movq and
move (or movp as you suggested). I uploaded a CL
https://codereview.chromium.org/91333002/ for your reference. If you are OK
with
this, I will change movq extensively in the X64 port.
