83f3bff643 add a bit of style 2008-09-27 00:15:45 -07:00

6efb930e19 gcc: Version 4.3 is pretty anal about shadowing types, placate it. 
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.

ce3d8c2b03 atomicio: provide atomic read and write functions. 
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.

f066db7fcd inifile: Whack preprocessor access. 
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.

496d3f2789 style: This file hugely violated the M5 style.

58c63ea8b1 Get rid of outputStream... wasn't really being used 
(except for warn()) and new -r/-e options make it
not worth fixing.

fe8aeff362 Add -r/-e options to redirect stdout/stderr. 
Better than using shell since it automatically uses -d directory
for output files (creating it as needed).

50ef39af82 sockets: Add a function to disable all listening sockets. 
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.

aa2bb4f7b9 Get rid of useless m5_assert macro. 
Its only purpose was to print the cycle number but that already
happens in the SIGABRT handler.  No one used it anyway.

a4a7a09e96 Remove delVirtPort() and make getVirtPort() only return cached version. 2008-07-01 10:25:07 -04:00
Ali Saidi
c5fbbf376a Change everything to use the cached virtPort rather than created their own 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.

87d03d00cd inet: initialization fixes. 
Make sure variables are properly initialized and also make sure that
truth testing works properly.

e71a5270a2 Make sure that output files are always checked success before they're used. 
Make OutputDirectory::resolve() private and change the functions using
resolve() to instead use create().

f6e5b92d63 ELF Loader: Use physical addresses instead of virtual ones. 
This works in SE mode because the virtual and physical addresses specified for
segments are the same. In Alpha, the LoadAddrMask is still necessary because
the virtual and physical addresses are the same and apparently rely on the
super page mechanism. All of the regressions pass.
