2011-08-08I am an idiot: remove the beginnings of an experimental tool that Injn1-2/+0
accidentally committed. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11957 a5019735-40e9-0310-863c-91ae7b9d1cf9
2011-08-08Fix a Massif bug: when realloc'ing a block, any values in the part of thenjn1-0/+2
block beyond the original request weren't copied. They are now. This is important because a program could use malloc_usable_size to gain legitimate access to those extra bytes. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11956 a5019735-40e9-0310-863c-91ae7b9d1cf9
2011-07-12Build system fixes so as to temporarily disable the GDBserver onsewardj1-1/+7
Android. Making that work will require a bit of extra effort due to minor glibc-vs-bionic differences. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11885 a5019735-40e9-0310-863c-91ae7b9d1cf9
2011-07-11The pthread.h on Android has no definition for pthread_rwlock_t, whichsewardj1-0/+20
makes the associated intercepts in Helgrind and DRD un-compilable. Add a configure test for it, and use them to guard the aforementioned intercepts. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11875 a5019735-40e9-0310-863c-91ae7b9d1cf9
2011-07-11Introduce the concept of platform variants. These allow furthersewardj1-0/+76
qualification of the normal (arch, os) pairings used to factorise the code base via the VGP_ defines. With this change, a new define VGPV_<arch>_<os>_<variant> is also passed to each compile. The initial motivation is to allow clean factorisation of Android-specific code, which is a minor variant of arm-linux, without having to introduce a complete new platform. In all other cases the supplied tag is simply "vanilla". Also add configure.in stuff to recognise Android at configure time. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11872 a5019735-40e9-0310-863c-91ae7b9d1cf9

2011-04-13s390x: rewrite some testcases. To make my testing and debugging lifesewardj1-44/+0
simpler, I've rewritten those testcases from none/tests/s390x that require binutils to recognize opcodes defined in the extended-immediate and general-instruction-extension facilities. As a side effect this change removes the special casing in none/tests/s390x/Makefile.am and the configury bits to support it. Fixes #270115.

2010-10-12Add DHAT as an experimental tool. DHAT (a Dynamic Heap Analysis Tool)sewardj1-0/+2
is a heap profiler that is complementary to Massif. DHAT tracks heap allocations, and connects which memory accesses are to which blocks. It can find the following information: * total allocation and max liveness * average block lifetime (# instructions between allocation and freeing) * average number of reads and writes to each byte in the block ("access ratios") * average of longest interval of non-access to a block, also measured in instructions * which fields of blocks are used a lot, and which aren't (hot-field profiling) Using these stats it is possible to identify allocation points with the following characteristics: * potential process-lifetime leaks (blocks allocated by the point just accumulate, and are freed only at the end of the run) * excessive turnover: points which chew through a lot of heap, even if it is not held onto for very long * excessively transient: points which allocate very short lived blocks * useless or underused allocations: blocks which are allocated but not completely filled in, or are filled in but not subsequently read. * blocks which see extended periods of inactivity. Could these perhaps be allocated later or freed sooner? * blocks with inefficient layout (hot fields spread out over multiple cache lines), or with alignment holes git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11431 a5019735-40e9-0310-863c-91ae7b9d1cf9
