2009-08-07Tidy up of messaging:sewardj1-1/+7
* For all tools and the core, don't show statistics when -v is in effect. Instead, try to restrict -v to mostly user-useful stuff. * A new flag --stats=no|yes [no] produces statistics output instead. * Fix longstanding problem in that Memcheck's leak checker ran after the core's error manager module shut down, thereby not showing use counts of leak suppressions. This fixes #186790. * As a consequence, the leak checker text output of Memcheck has changed a bit -- leak check is done before the final error summary is done (much more logical), and the output has been tidied up a bit. * Helgrind, Drd and Ptrcheck now also print "For counts of detected and suppressed errors, rerun with: -v", which makes them consistent with Memcheck in this regard. These are filtered out by the regtest filter scripts. For all tools except Memcheck, the regtests are unchanged. On Memcheck regtests still fail due to rearrangements of the leak checker output. This will be fixed by a followup commit. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10746 a5019735-40e9-0310-863c-91ae7b9d1cf9

2009-07-12Track vex r1907 (introduce Iop_CmpCas{EQ,NE}{8,16,32,64} and use themsewardj1-36/+43
for CAS-success? tests). Detailed background and rationale in memcheck/mc_translate, comment "COMMENT_ON_CasCmpEQ". This commit changes the Memcheck instrumentation of IRCAS so as not to do a definedness check on the success/failure indication. Also, by being able to identify via the Iop_CasCmpEQ primitives any such checks independently created by front ends, it can avoid instrumenting these too. All this is to avoid reporting new false positives observed on Fedora 7 (x86?) and openSUSE 10.2 (x86) following the recent merge of branches/DCAS. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10432 a5019735-40e9-0310-863c-91ae7b9d1cf9

2009-07-01Merge in branches/DCAS.sewardj1-57/+235
This branch adds proper support for atomic instructions, proper in the sense that the atomicity is preserved through the compilation pipeline, and thus in the instrumented code. These changes track the IR changes added by vex r1901. They primarily update the instrumentation functions in all tools to handle the changes, with the exception of exp-ptrcheck, which needs some further work in order to be able to run threaded code. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10392 a5019735-40e9-0310-863c-91ae7b9d1cf9

2009-06-03A number of changes relating to syscall numbering:njn1-12/+1
- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out differences in the way syscall numbers are printed on different platforms. This gets rid of seven "DDD" fixme-style comments. - This also meant that Darwin syscall numbers are now printed in a non-ambiguous way -- previously Unix, machine-dependent and diagnostic syscalls were all printed the same way, even though their numbers overlap. Now each number is prefixed with "unix", "mdep", etc. And Mach trap numbers aren't printed as negative numbers now that they have a "mach" prefix. - Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two parts, one suitable for inclusion in asm files, one suitable for inclusion in C files; in both cases the latter includes the former. This makes this module more like other modules that have asm-only components (eg. m_transtab); it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and tests to be removed. - Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed, and renamed some of the existing ones to make their meanings clearer. - Added comments on the encoding of Darwin syscall numbers so it's possible for mortals to understand without reading the kernel code.. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10218 a5019735-40e9-0310-863c-91ae7b9d1cf9
2009-05-28Merge the DARWIN branch onto the trunk.njn1-7/+40
I tried using 'svn merge' to do the merge but it did a terrible job and there were bazillions of conflicts. So instead I just took the diff between the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed the added files (no files needed to be 'svn remove'd) and committed. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10156 a5019735-40e9-0310-863c-91ae7b9d1cf9

Replace some uses of ULong in the address space manager with Off64T to match. Also add a comment explaining the meanings of the basic types like Addr, OffT, SizeT, etc. Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an Int. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@8959 a5019735-40e9-0310-863c-91ae7b9d1cf9

git-svn-id: svn://svn.valgrind.org/valgrind/trunk@8688 a5019735-40e9-0310-863c-91ae7b9d1cf9
2008-10-20On ppc32/64 we don't have a reliable way to detect function entriessewardj1-3/+5
and exits at the moment. So disable stack array bounds checking for ppc32/64 platforms. Also (unnecessarily) disables global array bounds checking on those platforms. Add a flag --enable-sg-checks=no|yes [yes] so that stack and global checking can be optionally disabled on any platform. This is useful because stack and global checking is much more expensive than heap checking, and so it may be desirable to disable it. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@8686 a5019735-40e9-0310-863c-91ae7b9d1cf9
