[PATCH v12 07/23] i386: move TCG cpu class initialization to tcg/ |
|
Date: |
Sat, 12 Dec 2020 16:55:14 +0100 |
to do this, we need to take code out of cpu.c and helper.c,
and also move some prototypes from cpu.h, for code that is
needed in tcg/xxx_helper.c, and which in turn is part of the
callbacks registered by the class initialization.
Therefore, do some shuffling of the parts of cpu.h that
are only relevant for tcg/, and put them in tcg/helper-tcg.h
For FT0 and similar macros, put them in tcg/fpu-helper.c
since they are used only there.
