Previously a loop was being done to check whether the
block was valid/secure or not. Variables have been
added to skip this loop and save and update sector
block state when sub-blocks are validated, invalidated
and secured.

This patch changes two members from being raw pointers to being STL
containers. The reason behind, other than cleanlyness and arguable OO
best practices is that containers have more intronspections capabilities
than naked pointers do, as the size is known.
Using STL containers adds little overhead and eases the automation of
process during debugging (gdb).

aarch64 floating point registers are now stored as vector type, but this

The size was not large enough for the 'G' packet on aarch64, which the
client sends to set registers.
This would lead to the stub not to be able to find the end of the input
packet and keep waiting forever.

The main change is to remove vector registers from the GDB stub.
Those registers were intended for SVE, which is a new architecture feature
and not yet treated by default on the GDB present in Ubuntu 18.04, and
possibly not even on GDB master.
As a result, aarch64 GDB stub connections would fail with:
Remote 'g' packet reply is too long
The correct way to support those registers is to send XML GDB target
description files to the client. This feature is not yet available for
any architecture, and should be implemented in future patches.
Other smaller fixes are:
* cpsr is uint32_t in aarch64 as well as arm
* use M5_ATTR_PACKED on the register structs since they are being cast and
sent as byte arrays

These versions don't support the std::put_time function. Since versions
of gcc older than 5.0 aren't going to be supported at all in the fairly
near future, this should only be temporary. The number of people using
both systemc and older versions of gcc should be very small, or even
zero.

Most tests were named *test where * was the base name of the file being
tested, but some were named differently based on, for instance, the
name of the class that file implemented.
This change makes all the test names consistently based off of the file
name they test, and also brings in the new .test convention to make
them easier to read.
Now, if you have a file like fiber.cc you want to test, you'd have a
unit test in a file called fiber.test.cc, and a test called fiber.test
which would generate a binary called fiber.test.opt, fiber.test.debug,
etc.

We were previously running them from the current directory to start
with, and then having the config script switch to the build directory.
That worked, except when output streams might be opened as part of the
global constructors which would run before the config script.
This change makes us start from the build directory directly, making
the switch in the config script unnecessary and ensuring that no files
leak outside of the build when running tests.

This will prevent some (but not all) output files the tests generate
from ending up outside the build directory. Because some output file
streams are constructed as global objects, their paths are resolved
relative to the CWD when gem5 starts, before the config script has a
chance to change it.
Subsequent changes will make verify.py should make gem5 start with the
correct working directory, cleaning up the remaining leaking files.

Neither assert(0) nor assert(false) give any hint as to why control
getting to them is bad, and their more descriptive versions,
assert(0 && "description") and assert(false && "description"), jury
rig assert to add an error message when the utility function panic()
already does that directly with better formatting options.
This change replaces that flavor of call to assert with panic, except
in the actual code which processes the formatting that panic uses (to
avoid infinitely recurring error handling), and in some *.sm files
since I don't know what rules those have to follow and don't want to

This function catches a couple types of exceptions the functions it
calls might throw, but if one that it doesn't catch is thrown, then
it will propogate that exception to its own callers, and not initialize
the value it was asked to convert.
This might be considered desirable behavior since it lets errors
propogate and avoids handling them in code that might not know the
context of when it's called. On the other hand, it upsets g++ since it
thinks that there might be an uninitialized value used elsewhere, even
though that value will only be uninitialized if an exception is
propogating, and the code that would use it is after a point where that
exception would have been caught and execution would have resumed.
To satisfy g++ and to also avoid silently hiding errors, this change
adds a catch all which will panic if an unexpected exception is raised.

Summary: Usage of const DynInstPtr& when possible and introduction of
move operators to RefCountingPtr.
In many places, scoped references to dynamic instructions do a copy of
the DynInstPtr when a reference would do. This is detrimental to
performance. On top of that, in case there is a need for reference
tracking for debugging, the redundant copies make the process much more
painful than it already is.
Also, from the theoretical point of view, a function/method that
defines a convenience name to access an instruction should not be
considered an owner of the data, i.e., doing a copy and not a reference
is not justified.
On a related topic, C++11 introduces move semantics, and those are
useful when, for example, there is a class modelling a HW structure that
contains a list, and has a getHeadOfList function, to prevent doing a
copy to an internal variable -> update pointer, remove from the list ->
update pointer, return value making a copy to the assined variable ->
update pointer, destroy the returned value -> update pointer.

Previously StridePrefetcher was only able to use random
replacement policy. This change allows all replacement
policies to be applied to the pc table.

Move the unordered_map outside of the PCTable, as it
belongs to the StridePrefetcher. By doing so we are
moving towards a table that ressembles the ones of
the Tags classes.
Some functions have been moved from the prefetcher to
the PCTable, as they didn't belong there. As such, they
have been renamed to remove the unnecessary prefix.

Return a pointer to the entry instead of returning a
boolean and passing a pointer reference. As a side
effect, change the name of the function to be more
descriptive of the functionality.
