2007-11-10Remove old Helgrind suppressions.sewardj1-59/+0

2006-12-16Completely overhauled the internals of Memcheck's error handling. All thenjn1-1/+1
different error kinds were reusing the same struct for storing their details. Each one used some but not all the fields, and the AddrInfo was similar, and it was very confusing. So I changed MC_Error and AddrInfo to be tagged unions, like Vex's IRExpr and IRStmt types. The resulting code is a little more verbose but much easier to understand. I also split up several error kinds, which also made things simpler. The user-visible behaviour is identical except for a couple of very minor things that I've documented in the NEWS file for the 3.3.0 release. Ideally I'd get rid of the Addr and Char* fields in the core Error type, which are not always used, and do them similarly within tools. But that would require changing the core/tool interface, so I'm leaving it for the moment. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6402 a5019735-40e9-0310-863c-91ae7b9d1cf9
2006-12-14Removed the unused pthread_model and thread_model modules.njn1-25/+0
Mostly commented out the unused stuff relating to ThreadErrs and MutexErrs, which no longer exist. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@6399 a5019735-40e9-0310-863c-91ae7b9d1cf9

2006-03-27Merge in the COMPVBITS branch to the trunk. This is a big change tonjn1-15/+15
Memcheck, replacing the 9-bits-per-byte shadow memory representation to a 2-bits-per-byte representation (with possibly a little more on the side) by taking advantage of the fact that extremely few memory bytes are partially defined. For the SPEC2k benchmarks with "test" inputs, this speeds up Memcheck by a (geometric mean) factor of 1.20, and reduces the size of shadow memory by a (geometric mean) factor of 4.26. At the same time, Addrcheck is removed. It hadn't worked for quite some time, and with these improvements in Memcheck its raisons-d'etre have shrivelled so much that it's not worth the effort to keep around. Hooray! Nb: this code hasn't been tested on PPC. If things go wrong, look first in the fast stack-handling functions (eg. mc_new_mem_stack_160, MC_(helperc_MAKE_STACK_UNINIT)). git-svn-id: svn://svn.valgrind.org/valgrind/trunk@5791 a5019735-40e9-0310-863c-91ae7b9d1cf9

2005-06-24Broaden a couple of suppressions so vgtest_ume passes on my machine.njn1-2/+7
(I wrote this in a commit message the other day, but I'd actually edited the generated default.supp file rather than the glibc-2.2.supp.) git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4008 a5019735-40e9-0310-863c-91ae7b9d1cf9
2005-03-15Memcheck complains a lot at glibc-2.2.5 startup, for unclear reasons.sewardj1-0/+8
This tries to shut it up a bit. This may not be a good fix. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3363 a5019735-40e9-0310-863c-91ae7b9d1cf9
2005-03-10Merge in changes from the 2.4.0 line. This basically brings in thesewardj1-12/+26
overhaul of the thread support. Many things are now probably broken, but at least with --tool=none, simple and not-so-simple threaded and non-thread programs work. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3265 a5019735-40e9-0310-863c-91ae7b9d1cf9

2003-11-14Started to rescind the name "skin", replacing it with "tool". Did this in allnethercote1-1/+1
the places that normal users will see: - command line: --tool=foo (although --skin=foo still works) - docs: removed all traces (included renaming coregrind_skins.html to coregrind_tools.html) - in the usage messages - in error messages Also did in in some places that I judged were unlikely to cause clashes with existing workspaces: - in the header comments of many files (eg. "This file is part of Memcheck, a Valgrind tool for...") - in the regtests script - in the .supp files - in AUTHORS - in README_MISSING_SYSCALL_OR_IOCTL Also update the AUTHORS file to mention Jeremy. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2027 a5019735-40e9-0310-863c-91ae7b9d1cf9

2002-11-13Merge patch from JeremyF:sewardj1-7/+1
22-mutex-destroy-unlock: It seems that glibc assumes in its internal use of pthreads that destroying a lock implicity unlocks it. This patch handles this case so that lock ownership tracking is accurate. Also handles the case of the dyanmic linker wanting to do locking before Valgrind has started up. vg_libpthread now implements toy lock/unlock functions to keep it happy and leave the locks in a sensible state. Implements some untested code to handle the case where a lock is taken before Valgrind is running but released afterwards. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1297 a5019735-40e9-0310-863c-91ae7b9d1cf9

skin_name1,skin_name2:supp_name No spaces are allowed on either side of the comma. This is useful for sharing suppressions between Addrcheck and Memcheck. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1205 a5019735-40e9-0310-863c-91ae7b9d1cf9

2002-10-02Qualifying suppression types with the skin name, like this:njn1-49/+57
memcheck:Addr4 Changed the `name' need of the memcheck skin from "valgrind" to "memcheck" for this. But the name Valgrind will return when I print core and skin names in the startup message. One issue is that some skins share suppression types, eg. memcheck and addrcheck. Might be useful to allow multi-skin suppressions, viz: memcheck,addrcheck:Addr4 This won't be too hard to tack on, though. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1163 a5019735-40e9-0310-863c-91ae7b9d1cf9
2002-09-27merge rev 1.8.2.1:sewardj1-0/+34
Add as many suppressions as I reasonably can for SuSE 8.1. There's still a lot of junk, but that can only be fixed by a more direct tackling of gcc-3.2's bad habits. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1112 a5019735-40e9-0310-863c-91ae7b9d1cf9
