7186fc4c2d arch,kern,sim: Use a map to map syscall flags. 
Use a std::map to map target syscall flag bits to host flag bits. This
avoids having to track the number of elements in the map separately.

71460cb13e sim,misc: Rename Int namespace as as_int 
As part of recent decisions regarding namespace
naming conventions, all namespaces will be changed
to snake case.

sim_clock::Int became sim_clock::as_int.

"as_int" was chosen because "int" is a reserved
keyword, and this namespace acts as a selector of
how to read the internal variables.

Another possibility to resolve this would be to
remove the namespaces "Float" and "Int" and use
unions instead.

213c9186de arch,cpu: Make the decoder width a property of the decoder. 
In this context, the decoder width is the number of bytes that are fed
into the decoder at once. This is frequently the same as the size of an
instruction, but in instructions with occasionally variable instruction
sizes (ARM, RISCV), or extremely variable instruction sizes (x86) there
may be no relation.

Rather than determining the amount of data to feed to the decoder based
on a MachInst type defined by each ISA, this new interface adds some new
properties to the base InstDecoder class each arch specific decoder
inherits from. These are the size of the incoming buffer, a pointer to
wherever that data should end up, and a mask for masking a PC value so
it aligns with the instruction size.

These values are filled in by a templated InstDecoder constructor which
is templated based on what would have historically been the MachInst
type.

Because the "moreBytes" method would historically accept a parameter of
type MachInst, this parameter has also been eliminated. Now, the
decoder's parent object should use the pointer and size values to fill
in the buffer moreBytes reads. Then when moreBytes is called, it just
uses the buffer without having to show what its type is externally.

1a33023815 arch-x86: Work around a bug in g++ 6 and 7. 
These versions of g++ don't handle parameter pack expansion correctly
when there is a parameter pack defined at the class level and then one
which is defined by the constructor itself. Even though it knows what
the outter parameter pack contains, it still re-assigns it to be empty
and puts all arguments into the later parameter pack.

To work around this problem, we will explicitly put the class level
parameters into a tuple, which we then have to go through extra
acrobatics to explode and pass into base class constructors.

That also means that in all subclasses, the arguments which go into the
tuple need to be wrapped in {}s to group them into constructor arguments
for the tuple.

When a fault is generated, it needs to be returned, and nothing else

check over and over if there was a fault and if other parts of the

This simplifies the logic a bit which should speed up execution, and
also makes life easier for the compiler since behavior is obvious and
doesn't have to be deduced from possible data values and ifs.

a84a15ab17 arch-arm: Fix FEAT_VMID16 for Self Hosted debug 
The existing code was querying the vmidbits but it was not checking the
VTCR_EL2.VS bit, which dynamically enables/disables VMID16

157e7e2e3b fastmodel: Fix scx_get_parameter_list for ARM fastmodels. 
The first non-critical piece of this CL removes the unused self
from the Python function signature.

Then also includes "stl.h" from pybind11 to allow the
implicit conversion from std::map<std::string, std::string>
to a Python dict (otherwise there will be a runtime (not compile time)
error when calling the function.

As the current implementation always throws an error because of the
missing stl.h I don't believe anyone is using this function, and as such
it should be safe to just change the signature of
scx_get_parameter_list.

1cecc752d7 arch-arm: Implement ARMv8.1-VMID16, 16-bit VMID 
In an Armv8.1 implementation, when EL2 is using AArch64, the VMID size
is an IMPLEMENTATION DEFINED choice of 8 bits or 16 bits.
When implemented, this feature is supported only when EL2 is using AArch64.
The ID_AA64MMFR1_EL1.VMIDBits field identifies the supported VMID size.

Found by manually checking the files in:

And occasionally checking some .cc files through
a similar methodology.

particularly to the reg microops, but made other types a little more
