These files aren't a collection of miscellaneous stuff, they're the
definition of the Logger interface, and a few utility macros for
calling into that interface (panic, warn, etc.).

This patch optimises the passing of StaticInstPtr by avoiding copying
the reference-counting pointer. This avoids first incrementing and
then decrementing the reference-counting pointer.

We currently use our own home-baked support for type-safe variadic
functions. This is confusing and somewhat limited (e.g., cprintf only
supports a limited number of arguments). This changeset converts all
uses of our internal varargs support to use C++11 variadic macros.
|

At least gcc 4.4.3 seems to get confused by the use of func both as a
template parameter and a member variable in the M5VarArgsFault
class. This causes the value of the member variable func to be
unpredictable in M5VarArgsFault objects. This changeset renames the
template parameter to remove this ambiguity.
|
|
These faults take varargs to their constructors which they print into a string
and pass to the M5DebugFault base class. They are basically faults wrapped
around panics, faults, warns, and warnonce-es so that they happen only at
commit.

These faults can panic/warn/warn_once, etc., instead of instructions doing
that themselves directly. That way, instructions can be speculatively
executed, and only if they're actually going to commit will their fault be
invoked and the panic, etc., happen.
