Valgrind aspects, to match vex r3124.
See bug 339778 - Linux/TileGx platform support to Valgrind
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15080
vgdb.c contained (conditionally compiled) "invoker" code to have ptrace syscalls
used to allow gdb/vgdb to connect to a valgrind process blocked in a syscall.
This "invoker" code is ptrace based.
Not all platforms are using ptrace.
=> refactor vgdb so as allow invoker code to be added more cleanly
for non ptrace based platforms (e.g. Darwin, Solaris).
* add file vgdb.h for:
- definition of the vgdb-invoker interface
- common declarations between vgdb.c and vgdb-invoker implementations
* move ptrace related code from vgdb.c to new file vgdb-invoker-ptrace.c
* new file vgdb-invoker-none.c containing an empty invoker implementation
used on platforms that do not (yet) have a invoker implementation
(e.g. android and darwin).
* modified Makefile.am to use one of the vgdb-invoker-*.c file depending
on the platform.
* small changes related to changing ptraceinvoker to invoker in various files:
gdbserver_tests/make_local_links, gdbserver_tests/nlcontrolc.vgtest,
gdbserver_tests/mcinvokeRU.vgtest, gdbserver_tests/nlsigvgdb.vgtest
gdbserver_tests/mcinvokeWS.vgtest, coregrind/m_gdbserver/README_DEVELOPERS
Patch from Ivo Raisr, slightly modified
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13743
Fix some tests on ppc-debian6,s390x + handled Nick Nethercote, Josef
Weidendorfer comments
* improved testing & related doc
- added option --vex-iropt-precise-memory-exns=yes to mcsig(no)pass.vgtest
+ updated manual-core.xml
- cleanup some comments in *.vgtest
- modified filter_gdb and filter_memcheck_monitor to
handle specific ppc/debian6.0 mcsig(no)pass output
handle specific s390x 'missing debug info'
- added more information in README_DEVELOPPERS on how to
investigate failing gdbserver tests.
* handled Nick Nethercote comment:
Replaced kludgy ms.snapshot detailed
by ms.detailed_snaphot
Updated documentation and test.
* handled Josef Weindendorfer comments:
- do not report an error if ptrace_scope file can't be read.
Instead, a debug trace is done if -d (debug) option given
- added an option -l to give the list of active Valgrind
gdbserver. Useful a.o. to support callgrind_control.
Updated documentation
- added ref. to vgdb help in the vgdb --help message
