2009-02-26CPA: Add new object for gathering critical path annotations.Ali Saidi
2009-02-23stats: reorganize how parameters are stored and accessed.Nathan Binkert
2009-02-23stats: move the limits stuff into the types.hh fileNathan Binkert
2009-02-23stats: get rid of the convoluted 'database' code.Nathan Binkert
Just use the stuff directly and things ought to be more clear
2009-02-23stats: Try to make the names of things more intuitive.Nathan Binkert
Basically, this means renaming several things called data to info, which is information about the statistics. Things that are named data now are actual data stored for the statistic.
2009-02-23stats: fix text printout for distributionsNathan Binkert
2009-02-23debug: Move debug_break into src/baseNathan Binkert

2009-01-19tracing: Add help strings for some of the trace flagsNathan Binkert
2009-01-06INET: Add functions to header types to get offset in packet and start of ↵Ali Saidi
payload; add function to split packet at last known header
2008-12-06flags: Change naming of functions to be clearerNathan Binkert

2008-12-05Automated merge with ssh://m5sim.org//repo/m5Lisa Hsu
2008-12-05This brings M5 closer to modernity - the kernel being advertised is newer so ↵Lisa Hsu
it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs.
2008-12-03cprintf: support a configurable width and precision ("*" in printf)Nathan Binkert
2008-11-15Output: Include gzstream package to allow automatically-gzipped outputClint Smullen
The gzstream package provides an ostream-interface for writing gzipped files. The package comes from: http://www.cs.unc.edu/Research/compgeom/gzstream/ And is distributed under the LGPL license. Both the license and version information has been preservered, though all other files in the package have been purged. Minor modifications to the code have been made. The output module detects when a filename ends in .gz and constructs an ogzstream object instead of an ofstream object. This works for both the create(...) and find(...) commands. Additionally, since gzstream objects needs to be closed to ensure proper file termination, I have the output deconstructor deleting all ostream's that it manages on behalf of find(...). At the moment, the only output file that I know this functionality works for is stats, i.e. by specifying "--stats-file=m5stats.txt.gz" on the command line.
2008-11-14Fix a bunch of bugs I introduced when I changed the flags stuff for packets.Nathan Binkert
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.
2008-11-10flags: Provide an object for managing boolean flags for an object.Nathan Binkert
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.
2008-11-10safe_cast: add a new cast function for casts that should always succeed.Nathan Binkert
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.
2008-11-10mem: Assert that requests have non-negative size.Steve Reinhardt
Would have saved me much debugging time if these had been in there previously.
2008-10-10cprintf: properly deal with pointer typesNathan Binkert
2008-10-10Rename the info function to inform to avoid likely name conflictsNathan Binkert
2008-10-10output: Make panic/fatal/warn more flexible so we can add some new ones.Nathan Binkert
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.
2008-10-10misc: remove #include <cassert> from misc.hh since not everyone needs it.Nathan Binkert
2008-10-09range_map: Add a method to find which range a single value falls into.Nathan Binkert
2008-10-09style: conform to M5 style.Nathan Binkert
2008-10-09stats: use properly signed types for looping and comparisonNathan Binkert
2008-10-09style: Bring statistics code in line with the proper style.Nathan Binkert
2008-10-02stats: Fix small bug pointed out by unit testing.Nathan Binkert
2008-10-02Output: Verify output files are open after opening them.Ali Saidi
2008-09-27gcc: Add extra parens to quell warnings.Nathan Binkert
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.
2008-09-27add a bit of styleNathan Binkert
2008-09-22gcc: Version 4.3 is pretty anal about shadowing types, placate it.Nathan Binkert
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.
2008-09-19atomicio: provide atomic read and write functions.Nathan Binkert
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.
2008-09-19Use C++ limits where applicable for portabilityNathan Binkert
2008-09-19Use the proper version of C++ headersNathan Binkert
2008-09-19Check the return value of I/O operations for failureNathan Binkert
2008-09-19inifile: Whack preprocessor access.Nathan Binkert
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.
2008-09-10style: Remove non-leading tabs everywhere they shouldn't be. Developers ↵Ali Saidi
should configure their editors to not insert tabs
2008-09-08style: This file hugely violated the M5 style.Nathan Binkert
Remove a bunch of unused cruft from the interface while we're at it
2008-08-04Get rid of outputStream... wasn't really being usedSteve Reinhardt
(except for warn()) and new -r/-e options make it not worth fixing.
2008-08-04Add -r/-e options to redirect stdout/stderr.Steve Reinhardt
Better than using shell since it automatically uses -d directory for output files (creating it as needed).
2008-08-03sockets: Add a function to disable all listening sockets.Nathan Binkert
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.
2008-07-15Get rid of useless m5_assert macro.Steve Reinhardt
Its only purpose was to print the cycle number but that already happens in the SIGABRT handler. No one used it anyway.
2008-07-01Remove delVirtPort() and make getVirtPort() only return cached version.Ali Saidi
2008-07-01Change everything to use the cached virtPort rather than created their own ↵Ali Saidi
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.
2008-06-17inet: initialization fixes.Nathan Binkert
Make sure variables are properly initialized and also make sure that truth testing works properly.
2008-06-12BitUnion: Take out namespace declaration so bitunions can be declared inside ↵Gabe Black
classes.
