From e3602b3eec0696b183722ea21da14588cf205c74 Mon Sep 17 00:00:00 2001
From: Mark Wielaard <mark@klomp.org>

Subject: [PATCH] Add --with-gdbscripts-dir=PATH configure option
Currently the gdb valgrind scripts are installed under VG_LIBDIR
which is normally pkglibexecdir which is likely not in the default
gdb safe-path (a list of directories from which it is safe to
auto-load files). So users will have to add the directory to their
.gdbinit file.
This patch adds a --with-gdbscripts-dir=PATH configure option that
sets VG_GDBSCRIPTS_DIR to the given PATH (${libexecdir}/valgrind if
not given). A user can also configure --without-gdbscripts-dir to
disable adding a .debug_gdb_scripts section to the vgpreload library
and installing the valgrind-monitor python scripts completely.
Use VG_GDBSCRIPTS_DIR as gdbscriptsdir to install the valgrind-monitor
python files and pass it with CPPFLAGS when building vg_preloaded.c
and vgdb.c to use instead of VG_LIBDIR.

Subject: [PATCH] Bug 470978 - s390x: Link the tools with -Wl,--s390-pgste
Programs that require the PGSTE mode to be enabled may currently fail
under Valgrind. In particular this affects qemu-kvm.
While it is also possible to enable the PGSTE mode globally with
sysctl vm.allocate_psgte=1
the problem can more easily be prevented by linking the Valgrind tools
with -Wl,--s390-pgste. Add a configure check if the linker supports this,
and activate the flag if it does.
To verify the intended result, the following shell command can be used to
list the executables having this flag set:
find . -type f -perm -u+x -execdir \
/bin/sh -c 'readelf -lW $0 2>/dev/null | grep PGSTE' {} \; -print

Subject: [PATCH] memcheck: Handle Err_ReallocSizeZero in MC_(eq_Error)
When an realloc size zero error is emitted MC_(eq_Error) is called to
see if the errors can be deduplicated. This crashed since
Err_ReallocSizeZero wasn't handled. Handle it like Err_Free.
Also add a testcase for this case and test with both
--realloc-zero-bytes-frees=yes and
--realloc-zero-bytes-frees=no.
Which will report a different number of errors.

Subject: [PATCH 2/2] Bug 470132 - s390x: Increase test coverage for VGM
Add more tests for the VGM instruction, to verify the fix for the VGM
wrap-around case. Also test setting unused bits in the I2 and I3 fields,
to check that Valgrind ignores them as it should.

Subject: [PATCH 1/2] Bug 470132 - s390x: Fix the wrap-around case in VGM
Valgrind's implementation of VGM is incomplete:
* It doesn't support generating a wrap-around bit mask. Such a mask
should result when the ending bit position is smaller than the starting
bit position. Valgrind runs into an assertion failure instead.
* It doesn't ignore unused bits in the I2 and I3 fields of the
instruction, as it should.
Fix this by re-implementing the main logic in s390_irgen_VGM().
