reset_used_unit_defs()/reset_all_defs() calls:
o removed resetting tprocdef.procstarttai/procendtai and
instead check in the debug writers whether the def is
in the current unit or not to determine whether we should
write debug info for it
o use the collected defs in the wpoinfo structure to reset
the wpo flags in the defs, instead of iterating over all
defs in the program and resetting them that way
- removed now unused "is_reset" flag from tmodule

units have changed, because these can influence the code of the

+ initial implementation of whole-program optimisation framework
+ implementation of whole-program devirtualisation
o use:
a) generate whole-program optimisation information (no need
to completely compile the program and all of its units
with -OW/-FW, only the main program is sufficient)
fpc -OWdevirtcalls -FWmyprog.wpo myprog
b) use it to optimise the program
fpc -B -Owdevirtcalls -Fwmyprog.wpo myprog
(the -B is not required, but only sources recompiled during
the second pass will actually be optimised -- if you want,
you can even rebuild the rtl devirtualised for a particular
program; and these options can obviously also be used
together with regular optimisation switches)
o warning:
- there are no checks yet to ensure that you do not use
units optimised for a particular program with another
program (or with a changed version of the same program)

* detect x.classtype.create constructs (with classtype = the
system.tobject.classtype method), and treat them as if a
"class of x" has been instantiated rather than a
"class of tobject". this required storing the instantiated
classrefs in their own array though, because at such a
point we don't have a "class of x" tdef available (so
now "x", and all other defs instantiated via a classref,
are now stored as tobjectdefs in a separate array)

+ -Owoptvmts whole program optimisation which replaces vmt entries
with method names of child classes in case the current class'
method can never be called (e.g., because this class is never
instantiated). As a result, such methods can then be removed
by dead code removal/smart linking (not much effect for either
the compiler, lazarus or a trivial lazarus app though).

+ symbol liveness wpo information extracted from smartlinked programs
(-OW/-Owsymbolliveness)
+ use symbol liveness information to improve devirtualisation (don't
consider classes created in code that has been dead code stripped).
This requires at least two passes of using wpo (first uses dead code
info to locate classes that are constructed only in dead code,
second pass uses this info to potentially further devirtualise).
I.e.:
1) generate initial liveness and devirtualisation feedback
fpc -FWtt.wpo -OWall tt.pp -Xs- -CX -XX
2) use previously generated feedback, and regenerate new feedback
based on this (i.e., disregard classes created in dead code)
fpc -FWtt-1.wpo -OWall -Fwtt.wo -Owall tt.pp -Xs- -CX -XX
3) use the newly generated feedback (in theory, it is possible
that even more opportunities pop up afterwards; you can
continue until the program does not get smaller anymore)
fpc -Fwtt-1.wpo -Owall tt.pp -CX -XX
* changed all message() to cgmessage() calls so the set codegenerror
* changed static fsectionhandlers field to a regular field called
fwpocomponents
* changed registration of wpocomponents: no longer happens in the
initialization section of their unit, but in the InitWpo routine
(which has been moved from the woinfo to the wpo unit). This way
you can register different classes based on the target/parameters.
+ added static method to twpocomponentbase for checking whether
the command line parameters don't conflict with the requested
optimisations (e.g. generating liveness info requires that
smartlinking is turned on)
+ added static method to twpocomponentbase to request the
section name
