Is there an easy way to get GOT[1] from a tool? I can sweep through the whole segment, checking with VG_(seginfo_sect_kind)(Addr) for the first address returning Vg_SectGOT, but that seems like wasting of time, as gotstart is a member of SegInfo. VG probably should provide iterator functions to allow a tool to browse through available debuginfo (as PIN has). Currently, we only have this for SegInfo via VG_(next_seginfo). What about SectInfo* VG_(first_sectinfo)(const SegInfo*); SectInfo* VG_(next_sectinfo)(const SectInfo*); Addr VG_(sectinfo_start)(const SectInfo*); SizeT VG_(sectinfo_size)(const SectInfo*); VgSectKind VG_(sectinfo_kind)(const SectInfo*); ? Similar for source files, debug lines, function symbols, data symbols... Perhaps this is overkill, and it should be only added when a tool ever will need it, as it probably has overhead. Another way would be to provide hooks for a tool to be notified about a debug info entry when being loaded, like SK_gotSymbol(const SegInfo*, const SymbolInfo*) with VG_(symbolinfo_name/kind/start/size). The tool could return a boolean to request that the SymbolInfo should be allocated until the segment is discarded. I really would like to add a callgrind mode being able to provide the info how often some data structure was accessed from which code. For this, I need above way to build up a structure for fast mapping of data addresses to data structure names. What is the general opinion here?

Greetings, FYI the regression test results on Debian GNU/Linux 3.1 (a.k.a. sarge) running Valgrind-3.1.SVN, revision 4840, VEX revision 1404. == 186 tests, 5 stderr failures, 1 stdout failure ================= memcheck/tests/pointer-trace (stderr) memcheck/tests/writev (stderr) none/tests/faultstatus (stderr) none/tests/fdleak_fcntl (stderr) none/tests/mremap2 (stdout) none/tests/x86/int (stderr) The failures of memcheck/tests/writev and none/tests/fdleak_fcntl can be fixed with additional .exp files. IIRC, the failures of none/tests/faultstatus and none/tests/x86/int are current restrictions in VEX. The failures of memcheck/tests/pointer-trace and none/tests/mremap2 are new ones that appeared after the merging in of the ASPACEM branch. The .out files from these failures are attached to this email. Do let me know if more information or a bug report is needed. I hope this helps in a small way to improve a great product.

different to the ppc32/Linux one, for example.)

Well, we use vki_off_t in syscall wrappers, and that definition comes from the appropriate vki-*.h header. OffT is more for our internal use, so hopefully it won't be a problem. I like the idea of SizeT and OffT being the same size. Nick |

All 4.4BSD derived systems (*BSD, Darwin) use 64-bit off_t on both 32-bit and 64-bit platforms. |

Hi, finally, I have a version which should work quite well with VG 3.0.x, both on x86 and AMD64. Please try it out from http://kcachegrind.sourceforge.net/callgrind-0.9.13-VG30-beta1.tar.gz I'm very interested in any feedback. Note that recently, I released a standalone KCachegrind bugfix version, which should compile fine on AMD64. Fixes: * Correct Ir counts (when cache simulation is switched off) and correct generation of jump arrow info. You can check this out with callgrind --dump-instr=yes --collect-jumps=yes <app> and look at KCachegrinds assembler annotation. E.g. "_dl_elf_hash" should look fine now (a BB of this function is an example of VEX generating a BB with 5 exits). * Correct handling of REP instructions (first in the history of Callgrind!). Example of REP on x86 (and probably on x86_64, too) can be found in memcpy. E.g. if cx=0 for a repz with memory access, the simulator will show Ir=1, but D=0. For this, I added a few more simulator calls (like 0I1Dr). * Better call graph generation with calls into the runtime linker, avoiding cycles (this previously went wrong on x86_64; the hack for x86 is removed). This works with special handling for "_dl_runtime_resolve": this function gets a flag "simulate a jump into another function via RET and CALL" (short: "pop-on-jump"). Checking for this function name does not work with newer glibc, as this function is not exported any more. When running callgrind/KCachegrind, and you do not see this function (but big cycles), look for the caller of "__libc_start_main". This should look like "0x0000000000ABCDEF". For further callgrind run, use "--pop-on-jump=0x0000000000ABCDEF" as further argument. Better would be to use GOT[1], as John Reiser pointed out, as this has to contain a pointer to runtime_resolve, according to the ABI. I will look into this before the release. Josef |

I've been looking a little at ML_(fd_allowed), in syswrap-generic.c.
This function decides which fds syscalls are allowed to create/use,
so that V's own fds don't get trashed.
This is a good thing; however I'm not sure I understand the logic.
- the first conditional reads
if ( (fd < 0 || fd >= VG_(fd_hard_limit) || fd == VG_(clo_log_fd))
&& VG_(showing_core_errors)() ) {
... stuff ...
return False;
}
which seems to imply that some part of the decision rests on
what VG_(showing_core_errors)() produces, iow on what sounds
like a setting in the error-displaying options. That seems a
little odd.
- what does the "Bool soft" parameter mean?
Can anyone clarify?
