overhaul of the thread support. Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

seem to be simply duplication of the x86 instruction set tests into
the addrcheck and helgrind trees. I'm not sure what this duplication
achieves.

string in valgrind.pc.in, so that they describe Valgrind as a "dynamic
binary instrumentation framework", and don't mention platforms at all.
I had to tweak the regtest filters a bit for this.

It compiles, but aborts immediately if you try to run it.
I didn't include ldt.c; I'm not sure how the LDT is used on AMD64. It can be
added later if necessary.
While doing this, did some 64-bit cleanness fixes:
- Added necessary intermediate casts to ULong to avoid warnings when converting
ThreadId to void* and vice versa, in vg_scheduler.c.
- Fixed VALGRIND_NON_SIMD_CALL[0123] to use 'long' as the return type.
- Fixed VALGRIND_PRINTF{,BACKTRACE} to use unsigned longs instead of unsigned
ints, as needed.
- Converted some offsets in vg_symtab2.h from "Int" to "OffT".
- Made strlen, strncat, etc, use SizeT instead of 'unsigned int' for the length
parameter.
- Couple of other minor things.
I had to insert some "#ifdef __amd64__" and "#ifndef __amd64__" guards in
places. In particular, in vg_mylibc.c, some of our syscall wrappers aren't
appropriate for AMD64 because the syscall numbering is a bit different in
places. This difference will have to be abstracted out somehow.
Also rewrote the sys_fcntl and sys_fcntl64 wrappers, as required for AMD64.
Also moved the ipc wrapper into x86, since it's not applicable for
AMD64. However, it is applicable (I think) for ARM, so it would be nice
to work out a way to share syscall wrappers between some, but not all,
archs. Hmm. Also now using the real IPC constants rather than magic
numbers in the wrapper.
Other non-AMD64-related fixes:
- ARM: fixed syscall table by accounting for the fact that syscall
numbers don't start at 0, but rather at 0x900000.
- Converted a few places to use ThreadId instead of 'int' or 'Int' for
thread IDs.
- Added both AMD64 and ARM (which I'd forgotten) entries to valgrind.spec.in.
- Tweaked comments in various places.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3136
run, though. There are lots of stubs to be filled in. (The asm ones currently
just have "swi" in them, which seems to cause seg faults.)
Also, some of the macros are decided dubious, especially:
ARCH_* are bogus
SYSCALL_RET is bogus
PLATFORM_SET_SYSCALL_RESULT is bogus
not sure about SET_SYSCALL_RETVAL
FIRST_STACK_FRAME et al -- bogus?
VG_MAX_JUMPS ?
And in stage2.lds, the 0x8048000 is almost certainly wrong
This required some tweakings of the core:
- some of the vki_*.h kernel types were fixed up
- had to disable the AM_PROG_CC_C_O macro in configure.in, because automake
(autoconf?) didn't like it...
- some "#ifdef __x86__" guards were introduced, for nasty x86 things I don't
yet know how to factor out (trampoline page muck, sysinfo page muck).
- fixed a minor stupidity in vg_proxylwp.c.
- moved the ptrace wrapper into the x86-linux part
- had to change the intercept mangling scheme, to use 'J' instead of '$' as the
escape char because GCC didn't like '$'. This is all very dubious, and only
works because none of our intercepted symbols contains a 'J'. To be fixed up
ASAP.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3120
- Added a hacky mechanism which prevents the regtest script from entering
directories for other architectures. (Eg. when running on x86/, it won't enter
a ppc/ subdir.)
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3045
which caused the test to be skipped if the CPU type wasn't appropriate,
with a "prereq" line, which specifies a command that must succeed before
the test is run.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3041
- Change regtest script to print a message if a test is skipped due to the cpu
being of the wrong type.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2803
- Rewrote tests/cputest.c so that it can apply to different kinds of
processors. The idea being that any arch-specific tests have a cpu_test:
label in their .vgtest file, so they'll only get executed if the right
machine is being used.
- Rewrote a bunch of .vgtest files accordingly.

Problem was that the malloc-replacing tools (memcheck, addrcheck, massif,
helgrind) would assert if a too-big malloc was attempted. Now they return 0 to
the client. I also cleaned up the code handling heap-block-metadata in Massif
and Addrcheck/Memcheck a little.
This exposed a nasty bug in VG_(client_alloc)() which wasn't checking if
find_map_space() was succeeding before attempting an mmap(). Before I added
the check, very big mallocs (eg 2GB) for Addrcheck were overwriting the client
space at address 0 and causing crashes.
Added a regtest to all the affected skins for this.

- If no tool is specified, V now gives a short message and a list of
available tools. This was meant to happen previously, but a bug prevented
it from working properly; it gave the usage message instead.
- If a bad option is given, V now gives a short message rather than the full
--help. This make V consistent with all other programs I looked at.
- Now returning 0 when you do 'valgrind --help' and 'valgrind --version'
as other programs do.
- Removed VG_(startup_logging)() and VG_(shutdown_logging)() as they were
empty and have been for a long time (always?).
- Added various tests for these scenarios. Had to change the regtest
script slightly to allow for malformed command lines.
This addresses bug (wishlist) #82999.

created by the test. Added appropriate lines to the Cachegrind and Massif
tests. Should prevent large numbers of files clogging up directories.

This patch adds translation tests for most of the basic x86 instructions and
fixes a few missing/broken instructions to work properly.

Patch to improve SSE/SS2 support
This patch should implement most of the missing SSE/SSE2 opcodes. About
the only ones it doesn't do are the MASKMOVxxx ones as they are quite
horrible and involved an implicit reference to EDI so I need to think
about them a bit more.
The patch also includes a set of tests for the MMX/SSE/SSE2 opcodes to
validate that they have the same effect under valgrind as they do when
run normally. In one or two cases this wasn't actually the case even
for some of the implemented opcodes, so I fixed those as well ;-)

Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

the places that normal users will see:
- command line: --tool=foo (although --skin=foo still works)
- docs: removed all traces (included renaming coregrind_skins.html to
coregrind_tools.html)
- in the usage messages
- in error messages
Also did in in some places that I judged were unlikely to cause clashes with
existing workspaces:
- in the header comments of many files (eg. "This file is part of Memcheck, a
Valgrind tool for...")
- in the regtests script
- in the .supp files
- in AUTHORS
- in README_MISSING_SYSCALL_OR_IOCTL
Also update the AUTHORS file to mention Jeremy.

requests to allow client code to print messages through Valgrind's
logging mechanism. The new requests are:
VALGRIND_PRINTF - do a normal printf (prefixed with **PID**)
VALGRIND_PRINTF_BACKTRACE - do a printf with stack trace
VALGRIND_INTERNAL_PRINTF - printf, but for internal use (prefixed with ==PID==)
VALGRIND_INTERNAL_PRINTF_BACKTRACE - as above, with backtrace

filters to strip out varying things, and changed outputs correspondingly. Yell
if this breaks them for you.

with the aim of making it more robust, more correct and perhaps faster.
This patch removes the need to poll blocking syscalls, by adding a proxy
LWP for each application thread. This LWP is a kernel thread whose job
is to run all (potentially) blocking syscalls, and also to handle signals.
This allows the kernel to do more of the work of dealing with signals,
so on kernels which do this properly (2.6), Valgrind's behavious is a
lot more posix compliant. On base 2.4 kernels, we emulate some of the
missing 2.6 functionality.

Updated the basic test stderr filter to strip out line numbers from
vg_intercept.c
MERGE TO STABLE

CPUID.
Also added filters to Makefiles where missing; "make regtest" was broken
within distributions created using "make dist", now fixed.

- changed deprecated INCLUDES variable to AM_CPPFLAGS
- moved the -DVG_LIBDIR definition from AM_CFLAGS into AM_CPPFLAGS
- generally neatened them up a bit -- removed old commented out stuff, fixed a
couple of other minor things
Everything works for me, hopefully it won't break things for anyone else...

under some setups.
Also fixed problem with Cachegrind tests, by filtering out P4s'
warning message.
Also fixed 'mismatches'.

requiring "make install". This is good for two reasons:
1. shorter compile times ("make" instead of "make install")
2. don't need to install before running the regression tests
Changes:
- root Makefile now builds a libpthread.so.0 symlink to libpthread.so, which
was needed.
- startup script accepts a --in-place=<dir> option for running a non-installed
version, where <dir> is the root of the src tree
- VG_(mash_LD_PRELOAD_and_LD_LIBRARY_PATH) had to be fiddled with a bit
- tests/vg_regtest now uses the --in-place option to test the non-installed
version
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1614
installed, as it was silly since the reg tests themselves aren't installed.
Updated the "make regtest" target to use the uninstalled version in tests/.
Also, vg_regtest now no longer uses the installed version of Valgrind to do the
testing, but instead coregrind/valgrind. This means that you don't have to do
make install with your buggy changes before running the regtests on them :)
I even updated the RPM package .spec file!
Thanks to Dirk M�ller for the suggestion.
