Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
We have a lot of enumerations; by declaring fields as such, we make it
easier when debugging, since the debugger can display the enumerations
in cleartext. However, make sure exceptional values (like -1) are
included in the enumeration, since the compiler otherwise may not
include it in the valid range of the enumeration.
Get rid of magic open-coded register numbers. We now keep track of
a total of three different kinds of register numbers: the register
enumeration (regs.h), the x86 register value, and the register flags.
That has all the information we need.
Additionally, do massive revamping of the EA generation code and the
REX generation logic.
64-bit support for ndisasm. This is very much an initial attempt, and
there are guaranteed to be bugs in the code. However, some *very*
preliminary testing seems to indicate it's not completely off-base.
64-bit support required some major changes to regs.dat; clean some of
it up (re-introduce patterns, where appropriate) and allow a single
register to belong to multiple disassembly classes; also keep track
of the x86 register number again.
a) Automatically generate dependencies for all Makefiles;
b) Move register definitions to a separate .dat file;
c) Add support for "unimplemented but there in theory" registers.
