2009-07-15Merge coregrind/ changes from branches/MESSAGING_TIDYUP r10464.sewardj1-16/+19
This commit tidies up and rationalises what could be called the "messaging" system -- that part of V to do with presenting output to the user. In particular it brings significant improvements to XML output. Changes are: * XML and normal text output now have separate file descriptors, which solves longstanding problems for XML consumers caused by the XML output getting polluted by unexpected non-XML output. * This also means that we no longer have to hardwire all manner of output settings (verbosity, etc) when XML is requested. * The XML output format has been revised, cleaned up, and made more suitable for use by error detecting tools in general (various Memcheck-specific features have been removed). XML output is enabled for Ptrcheck and Helgrind, and Memcheck is updated to the new format. * One side effect is that the behaviour of VG_(message) has been made to be consistent with printf: it no longer automatically adds a newline at the end of the output. This means multiple calls to it can be used to build up a single line message; or a single call can write a multi-line message. The ==pid== preamble is automatically inserted at each newline. * VG_(message)(Vg_UserMsg, ..args..) now has the abbreviated form VG_(UMSG)(..args..); ditto VG_(DMSG) for Vg_DebugMsg and VG_(EMSG) for Vg_DebugExtraMsg. A couple of other useful printf derivatives have been added to pub_tool_libcprint.h, most particularly VG_(vcbprintf). * There's a small change in the core-tool interface to do with error handling: VG_(needs_tool_errors) has a new method void (*before_pp_Error)(Error* err) which, if non-NULL, is called just before void (*pp_Error)(Error* err). This is to give tools the chance to look at errors before any part of them is printed, so they can print any XML preamble they like. * coregrind/m_errormgr.c has been overhauled and cleaned up, and is a bit simpler and more commented. In particular pp_Error and VG_(maybe_record_error) are significantly changed. The diff is huge, but mostly very boring. Most of the changes are of the form - VG_(message)(Vg_UserMsg, "this is a message %d", n); + VG_(message)(Vg_UserMsg, "this is a message %d\n", n); Unfortunately as a result of this, it touches a large number of source files. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10465 a5019735-40e9-0310-863c-91ae7b9d1cf9

2009-05-28Merge the DARWIN branch onto the trunk.njn1-3/+3
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

2006-10-14Create a new module, m_vki, and move all knowledge about the kernelsewardj1-0/+1
interface, except for the syscall numbers, into that. Mostly this means moving include/vki-*.h to include/vki/vki-*.h. include/pub_tool_basics.h previously dragged in the entire kernel interface. I've done away with that, so that modules which need to see the kernel interface now have to include pub_{core,tool}_vki.h explicitly. This is why there are many modified .c files -- they have all acquired an extra #include line. This certainly breaks all platforms except x86.

2005-09-27This commit merges in changes from branches/ASPACEM (specifically,sewardj1-2/+1
changes from r4341 through r4787 inclusive). That branch is now dead. Please do not commit anything else to it. For the most part the merge was not troublesome. The main areas of uncertainty are: - build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am and include it in a couple of places. Building etc seems to still work, but I haven't tried building the documentation. - syscall wrappers: Following analysis by Greg & Nick, a whole lot of stuff was moved from -generic to -linux after the branch was created. I think that is satisfactorily glued back together now. - Regtests: although this appears to work, no .out files appear, which is strange, and makes it hard to diagnose regtest failures. In particular memcheck/tests/x86/scalar.stderr.exp remains in a conflicted state. - amd64 is broken (slightly), and ppc32 will be unbuildable. I'll attend to the former shortly. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4789 a5019735-40e9-0310-863c-91ae7b9d1cf9
2005-08-19Incorporate a patch from Craig Chaney which gives better stacksewardj1-9/+10
snapshots on ppc32-linux in the presence of functions subject to leaf-function optimisations. At the same time, simplify the stack unwinding logic by basically implementing it separately for each target. Having a single piece of logic for amd64 and x86 was tenable, but merging ppc32 into it is too confusing. So now there is an x86/amd64 unwinder and a ppc32 unwinder. This requires plumbing a link-register value into VG_(get_StackTrace2), and that in turn requires passing it around several other stack-trace-related functions. Hence 7 changed files. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4464 a5019735-40e9-0310-863c-91ae7b9d1cf9

2005-06-19Final commit for the initial modularisation pass:njn1-4/+21
- Broke part of m_scheduler off into a new module m_threadstate. It contains ThreadState, VG_(threads)[] and some basic operations on the thread table. All simple stuff, the complex stuff stays in m_scheduler. This avoids lots of circular dependencies between m_scheduler and other modules. - Managed to finally remove core.h and tool.h, double hurrah! - Introduced pub_tool_basics.h and pub_core_basics.h, one of which is include by every single C file. - Lots of little cleanups and changes related to the above. - I even did a small amount of documentation updating. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3944 a5019735-40e9-0310-863c-91ae7b9d1cf9
