2009-07-15Merge coregrind/ changes from branches/MESSAGING_TIDYUP r10464.sewardj6-21/+23
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
2009-06-24This commit merges the BUILD_TWEAKS branch onto the trunk. It has thenjn8-7/+39
following improvements: - Arch/OS/platform-specific files are now included/excluded via the preprocessor, rather than via the build system. This is more consistent (we use the pre-processor for small arch/OS/platform-specific chunks within files) and makes the build system much simpler, as the sources for all programs are the same on all platforms. - Vast amounts of cut+paste Makefile.am code has been factored out. If a new platform is implemented, you need to add 11 extra Makefile.am lines. Previously it was over 100 lines. - Vex has been autotoolised. Dependency checking now works in Vex (no more incomplete builds). Parallel builds now also work. --with-vex no longer works; it's little use and a pain to support. VEX/Makefile is still in the Vex repository and gets overwritten at configure-time; it should probably be renamed Makefile-gcc to avoid possible problems, such as accidentally committing a generated Makefile. There's a bunch of hacky copying to deal with the fact that autotools don't handle same-named files in different directories. Julian plans to rename the files to avoid this problem. - Various small Makefile.am things have been made more standard automake style, eg. the use of pkginclude/pkglib prefixes instead of rolling our own. - The existing five top-level Makefile.am include files have been consolidated into three. - Most Makefile.am files now are structured more clearly, with comment headers separating sections, declarations relating to the same things next to each other, better spacing and layout, etc. - Removed the unused exp-ptrcheck/tests/x86 directory. - Renamed some XML files. - Factored out some duplicated dSYM handling code. - Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting Makefile.am files to be much more standard. - Cleaned up m_coredump by merging a bunch of files that had been overzealously separated. The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude the added Makefile.vex.am, or 997 once the hacky file copying for Vex is removed. And the build system is much simpler. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10364 a5019735-40e9-0310-863c-91ae7b9d1cf9
2009-05-28Merge the DARWIN branch onto the trunk.njn2-0/+300
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

support to Memcheck for tracking the origin of uninitialised values, if you use the --track-origins=yes flag.

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,sewardj4-24/+8
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

things. These made sense when the arch/OS/platform-specific code was in one module, but as that code got mixed in with generic code the boundary between generic and non-generic blurred, and the distinction made less sense. So let's get rid of them. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4002 a5019735-40e9-0310-863c-91ae7b9d1cf9
2005-06-21Simplify the implementation of m_trampoline and the stuff that referssewardj2-6/+3
to it. Now there are no more offsets and no copying of code into the stack. We just redirect directly to entry points in m_syscalls.S. This will mess up pointercheck, since the redirect targets are now in Valgrind's address space, not the client's. But pointercheck is hosed anyway, and I'd rather back off to something simple whilst ppc32 is stabilised. When the address space management stuff is overhauled then pointercheck may or may not get reinstated, and if it does then the trampoline stuff will need revisiting. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3977 a5019735-40e9-0310-863c-91ae7b9d1cf9

2005-06-19Final commit for the initial modularisation pass:njn3-7/+5
- 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

2005-06-02Started modularising vg_mylibc. Put all the standalone stuff -- ie. notnjn2-0/+2
relying on any other modules -- in m_libcbase. Also converted the 'size' parameters to functions like VG_(memcpy) and VG_(strncpy) from Int to SizeT, as they should be. Also removed VG_(atoll16) and VG_(toupper), which weren't being used. Also made VG_(atoll36) less flexible -- it now only does base-36 numbers instead of any base in the range 2..36, since base-36 is the only one we need. As part of that, I fixed a horrible bug in it which caused it to return incorrect answers for any number containing the digits 'A'..'I'! (Eg. for "A; it would return 17 instead of 10!) Had to disable the assertions in VG_(string_match), since this module can't see vg_assert, which wasn't ideal but also isn't a disaster. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3838 a5019735-40e9-0310-863c-91ae7b9d1cf9
