and VG_(am_get_segment_starts) to indicate which segments
should be collected. That should solve the following problem:
in m_main.c we used to:
seg_starts = VG_(get_segment_starts)( &n_seg_starts );
for (i = 0; i < n_seg_starts; i++) {
Word j, n;
NSegment const* seg
= VG_(am_find_nsegment)( seg_starts[i] );
vg_assert(seg);
if (seg->kind == SkFileC || seg->kind == SkAnonC) {
...
// ... dynamic memory allocation for valgrind
...
}
This caused the vassert(seg) to fire because the dynamic memory
allocation further down the loop changed segments such that a
valgrind segment which used to be non-SkFree suddenly became
SkFree and hence VG_(am_find_nsegment) returned NULL. Whoom.
With this revision we only collect the segments we're really
interested in. For the example above that is all client segments.
So if V allocates memory -- fine. That will not change the layout
of client segments.

and rename VG_(am_set_segment_hasT_if_SkFileC_or_SkAnonC) to
VG_(am_set_segment_hasT_if_client_segment). Change it so it handles
all client segments.

The validity of this change follows from the following observations:
(1) There is a single source for allocating and storing segment names,
namely allocate_segname.
(2) For all invocations of allocate_segname the returned value (which
represents the segmant name) is assigned to NSegment::fnIdx.
(3) All but one assignments to NSegment::fnIdx assign allocate_segname.
The single exception assigns -1 in init_nsegment. That function is
called whenever a new segment (named or unnamed) is allocated.
For a segment name to become unused there must be an assignment to
NSegment::fnIdx which was previously assigned a return value from
allocate_segname. There is no such assignment.
It follows that all segment names are in use at all times, hence
SegName::inUse == True for all SegNames. So we can constant fold it
and don't need to represent it.
Pass 3 in preen_nsegments is obsolete as there are no segment names to
garbage collect.

address space manager. Callers should neither modify the string nor
free it (as the string resides is statically allocated memory). That
calls for a const HChar *
The type change exposed two bugs. One in m_addrinfo.c and one in
m_debuginfo.c. In both cases the returned string could possibly be freed later
on. So we need to strdup it first. Now fixed.

that are memory offsets) with PtrdiffT; OffT should only be used for file
sizes and offsets.
Change Off64T from a ULong to a Long, as it should be. Replace some uses
of ULong in the address space manager with Off64T to match.
Also add a comment explaining the meanings of the basic types like Addr,
OffT, SizeT, etc.
Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an
Int.

hardwire the assumption that an inode number is a UWord, that is, a
host word. There's no reason for that assumption to be valid; an
inode number could be a 64-bit int even on a 32 bit platform (eg w.r.t
sys_stat64). This commit changes inode numbers and, for good measure,
dev numbers, to be 64-bit regardless.

Memcheck, replacing the 9-bits-per-byte shadow memory representation to a
2-bits-per-byte representation (with possibly a little more on the side) by
taking advantage of the fact that extremely few memory bytes are partially
defined.
For the SPEC2k benchmarks with "test" inputs, this speeds up Memcheck by a
(geometric mean) factor of 1.20, and reduces the size of shadow memory by a
(geometric mean) factor of 4.26.
At the same time, Addrcheck is removed. It hadn't worked for quite some
time, and with these improvements in Memcheck its raisons-d'etre have
shrivelled so much that it's not worth the effort to keep around. Hooray!
Nb: this code hasn't been tested on PPC. If things go wrong, look first in
the fast stack-handling functions (eg. mc_new_mem_stack_160,
MC_(helperc_MAKE_STACK_UNINIT)).

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.

the unused init_shadow_page() function. As a result, m_aspacemgr no longer
depends on m_libcmman, breaking a circular module dependency, good!

- VG_(sanity_check_needs)() now returns a message to m_main if it fails,
for m_main to print and abort, rather than printing an error message and
aborting itself. This removes the dependency on m_libcprint and
m_libcassert.
- Passing in an extra param to VG_(sanity_check_needs)() that says if
shadow memory has been allocated, rather than using
VG_(get_shadow_size)(). This removes the dependency on m_aspacemgr.
