files, into vg_skin.h:
uInstr0, uInstr1, uInstr2, uInstr3, nameIReg, nameISize, nameSReg,
newTemp, newShadow, uLiteral, uCCall
As macros they avoid namespace problems (they expand to VG_(whatever)) so
this should work fine.

Added "version" and "copyright_author" fields for skins to supply.
Now startup message looks something like this:
==12698== cachegrind, an I1/D1/L2 cache profiler for x86-linux.
==12698== Copyright (C) 2002, and GNU GPL'd, by Nicholas Nethercote.
==12698== Built with valgrind-HEAD, a program execution monitor.
==12698== Copyright (C) 2000-2002, and GNU GPL'd, by Julian Seward.
==12698== Estimated CPU clock rate is 1422 MHz
==12698== For more details, rerun with: -v
The skin can specify a version number, but the skins that will be distributed
with Valgrind don't.
Also changed "x86 GNU/Linux" to the wicked "x86-linux" at Julian's request.
Updated default regression test filter to handle this new startup message.
----
Also moved the skin's name, description, etc., fields out of VG_(needs) into a
new struct VG_(details), since they are logically quite different to the needs.
Did a little code formatting, etc., for this. Updated skin docs
correspondingly, too.
Also renamed the need `run_libc_freeres' --> `libc_freeres' so it's a noun
phrase rather than a verb phrase.

from core error ones:
- Split up VG_(panic) into VG_(core_panic) and VG_(skin_panic)
- Likewise, split vg_assert into vg_assert and sk_assert
- Added a new need string: `bug_reports_to'
- Removed VG_(skin_error) which was a previous wussy attempt at this change.
This removed the need for the hacky redeclaration of VG_(skin_error) in
vg_profile.c, which is good.
At the moment, Julian and Nick's email addresses are hard-coded into each skin
individually, rather than using a #define in vg_skin.h, because that didn't
feel quite right to me... jseward@acm.org is still done with a #define for
core errors, though.

- added some missing SUBDIRS variables
- removed unnecessary coregrind/demangle/ from some INCLUDES lists

use_under_scores instead, to be consistent.
Also added some missing 'extern's on function declarations in vg_skin.h.
Also added a quick note in vg_regtest.in on the simplest way to run regression
tests.

--dev, because the old ones were now totally confusing (since --head no longer
applies to HEAD). Had to change a couple of .vgtest "vgopt:" lines for this.
Unfortunately the --stable result files are still *.stderr.exp.hd" because
changing them via CVS is a pain.
Also improved documentation in script slightly.

- changed lots of Makefile.am files
- changed configure.in
- changed lots of #include lines for changed file names
- changed lots of file headers n footers for changed file names
- changed vg_regtest to handle new directory structure -- recursively
traverses subdirectories for .vgtest test files
- changed lots of paths in memcheck/ regression test expected outputs

individual x86 instructions can be found when instrumenting UCode. However,
EIP is not needed during execution, because the x86 instr addresses are copied
into the cost-centres. So now they INCEIPs are removed during the
instrumentation step once their task is done.
This reduces running times by about 3--7%, and translation sizes by about 9%
(code expansion reduced from about 11x to about 10x).

These are the first of a generic family for calling C functions. CCALL_M_N
calls a function with M word-sized arguments and N word-sized return values
(N == 0 or 1, of course). All stack management is done automatically --
register saving, argument pushing, register restoring. Rough timings show it's
marginally faster (~3%), probably because the instrumentation phase is slightly
simpler and translations are slighly more compact.
It was introduced because the way Cachegrind was calling its helper functions
was not really legitimate -- it involved pushing RealRegs at a point where
RealRegs shouldn't have been used. This flukily worked for Cachegrind, but
caused obscure seg faults when I tried using the same technique for the DIDUCE
stuff. Hence this more general approach.
CCALL_M_N where M+N <= 3 are easy. More args might be done by abusing spare
fields in the UInstr struct, if really necessary. But it's not, yet.

to 4096, to possibly avoid deadlocks under very rare circumstances.
Is fully documented and commented.

- fixed a bug that was breaking the --threshold option.
vg_cachesim.c:
- fixed a bug that meant instructions that didn't have a line number in the
debug info were being written in cachegrind.out with whatever was the
last known line number. Now using 0.

automatic cache configuration detection using the CPUID instruction.
This can be overridden from the command-line if necessary.
vg_include.h:
- added the cache_t type and UNDEFINED_CACHE macro
- added command line args (of type cache_t) allowing manual override of
I1/D1/L2 configuration
- added log2(), which is generally useful
vg_main.c, valgrind.in, cachegrind.in:
- added handling of the new --{I1,D1,L2}=<size>,<assoc>,<line_size>
options
vg_cachesim.c:
- lots of stuff for auto-detecting cache configuration with CPUID.
Only handles Intel and AMD chips at the moment, and possibly not all of
them. Falls back onto defaults if anything goes wrong, and the configs
can be manually overridden from the command line anyway.
- now not printing cache summary stats if verbosity == 0. Still writing
cachegrind.out, though.
vg_cachesim_gen.c:
- new file containing stuff shared by the I1/D1/L2 simulations
vg_cachesim_{I1,D1,L2}:
- removed most of it; each now just calls a macro defined in
vg_cachesim_gen.c
vg_cachegen:
- has been cvs removed as it is no longer needed.
Makefile.am:
- added vg_cachesim_gen.c
- removed vg_cachegen
configure.in:
- removed vg_cachegen

VG_(cachesim_discard_notify) is called, the cost centre array for the basic
block is removed from the table, and its counts are aggregated into a single
"discard" cost centre, and the cost centre array is free'd.
The aggregate discard cost centre is given the filename:function_name
"(discarded):(discarded)". Mentioned this in the manual.
Only tested with tests/discard.c. Seems to work well for that case though :)

as well as LD_PRELOAD, so as to make our libpthread.so go out of scope
when a child which we don't want to trace, is exec'd. Otherwise the
child can wind up being connected to our libpthread.so but not to
valgrind.so, which is an unworkable combination; you have to be connected
to both or neither.
