833c095f5c Callgrind manual: rewriting start of section about avoding cycles 
This hopefully makes the whole issue with cycles easier to understand.
And no, this does not get rid of the description of cycles, carefully
crafted by Julian ;-)

db1e230c31 Callgrind: improve documentation 
* Looks a little bit more like the Cachegrind manual
  (at least in front)
* Removed the out-of-place general section about profiling
  and gprof. Perhaps something like this can be put at
  another place
* Notes about Callgrinds problems with call tracing on PPC
* Include usage of callgrind_annotate, and note its lack of
  cycle detection

e16417ddf7 Add branch-misprediction profiling to Cachegrind. When the (new) flag 
--branch-sim=yes is specified, Cachegrind simulates a simple indirect
branch predictor and a conditional branch predictor.  The latter
considers both the branch instruction's address and the behaviour of
the last few conditional branches.  Return stack prediction is not
modelled.

The new counted events are: conditional branches (Bc), mispredicted
conditional branches (Bcm), indirect branches (Bi) and mispredicted
indirect branches (Bim).  Postprocessing tools (cg_annotate, cg_merge)
handle the new events as you would expect.  Note that branch
simulation is not enabled by default as it gives a 20%-25% slowdown,
so you need to ask for it explicitly using --branch-sim=yes.

7a897aa86d When doing 'demo' translations for --profile-flags=, make at least 
some attempt to discard existing translations first.  Otherwise
Cachegrind (rightly) asserts on the basis that it is seeing duplicate
translation requests for the same entry point.

14b9b8b8d2 Make ptrace-based launchers able to handle --help, --version etc. 
Problem is that --help etc are handled by the tool exe.  But a
ptrace-based launch scheme can't run "no program" if the user just
types "valgrind --help" because the launcher depends on starting the
client first and only then attaching valgrind to it using ptrace.  So
instead provide a dummy do-nothing program to run when no program is
specified.  m_main notices this and acts as if there really had been
no program specified.

This has no effect at all on Linux/ELF program launching.
