I did some of the flags and assertions wrong. Thanks to Brad Beckmann
for pointing this out. I should have run the opt regressions instead
of the fast. I also screwed up some of the logical functions in the Flags
class.
|
|
In many cases it might be preferable to use bitset, but this object
allows the user more easily manipulate groups of flags because the
underlying type (e.g. uint64_t) is exposed.

In DEBUG mode, this does a dynamic_cast and asserts that the result is
non null. Otherwise, it just does a static_cast. Again, this is only
intended for cases where the cast should always succeed and what's
desired is a debugging check to make sure.

Would have saved me much debugging time if these
had been in there previously.

The major thrust of this change is to limit the amount of code
duplication surrounding the code for these functions. This code also
adds two new message types called info and hack. Info is meant to be
less harsh than warn so people don't get confused and start thinking
that the simulator is broken. Hack is a way for people to add runtime
messages indicating that the simulator just executed a code "hack"
that should probably be fixed. The benefit of knowing about these
code hacks is that it will let people know what sorts of inaccuracies
or potential bugs might be entering their experiments. Finally, I've
added some flags to turn on and off these message types so command
line options can change them.

Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off. Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.

In the future, it would be nice to put the O3CPU into its own
namespace so that we don't end up hardcoding pointers to the global
namespace.

These functions keep trying to read and write until all data has been
transferred, or an error occurrs. In the case where an end of file
hasn't been reached, but all of the bytes have not been read/written,
try again. On EINTR, try again.

We haven't used the preprocessor feature of the inifile stuff in a
very long time, so let's get rid of it since it would otherwise take
effort to maintain.

Better than using shell since it automatically uses -d directory
for output files (creating it as needed).

When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb. Expose a function to disable those ports, and have the
regression scripts disable them. There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.

Its only purpose was to print the cycle number but that already
happens in the SIGABRT handler. No one used it anyway.

each time.
This appears to work, but I don't want to commit it until it gets tested a lot more.
I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.

Make sure variables are properly initialized and also make sure that
truth testing works properly.

Make OutputDirectory::resolve() private and change the functions using
resolve() to instead use create().

Also some bug fixes in MIPS ISA uncovered by g++ warnings
(Python string compares don't work in C++!).
