This basically revives the globalasmsym entry of the PPU though it feeds to different lists, one for the public (exported) symbols and one for the external (imported) symbols. Also the list of symbols is much smaller as it would be if all symbols would be dumped in there.

Respect DenyPackageUnit flag.
pmodules.pas, proc_package:

Do not check whether all units are used as by definition all units of a package are considered as used.
pmodules.pas, proc_package:

........
Check whether a unit has been implicitely imported in a package. A unit is considered as implicitely imported if it is not part of a required package nor part of the units listed in the contains section. This note is useful (Delphi even provides a dialog in that case) as a package with implicitely imported units /might/ become incompatible with other packages (e.g. if another package includes that unit uses that package and includes that unit explicitely; of course that is the same as if both package included it explicitely, but with the hint one knows where to look).

fpcp.pas, tpcppackage:

+ new method writeppudata() which rewrites all contained PPUs directly into the PCP after the ibend entry (Note: the data is written 16 Byte aligned to ease viewing of the PCP and its contained PPUs in a hex editor)

* clear the list of packages in case the user passed any using -FPxxx
* parse the "requires" section like a list of units and add each full identifier as a package to load
* before parsing the "contains" section load all packages, so that all units can be correctly resolved
........
Correctly create import libraries for packages as well.
pkgutil.pas, createimportlibfromexternals:
* instead of processing units without the uf_in_library flag, only process those that don't have a package reference set (thus becoming part of the program/library or the package)
- remove unneeded "pkg" parameter
pmodules.pas:
+ proc_package: create the import library if the package requires other packages
* proc_program: adjust call to createimportlibfromexternals
........
Ensure that the reference to the System unit is correctly set up for packages. Among other things this is needed to compile a package with the -gl option (though debug information doesn't work yet).
pmodules.pas:
* convert AddUnit to a function and let it return the newly loaded module
* proc_package: when parsing the contained units ensure that we correctly set up the System unit reference if we are to contain the System unit
* proc_package: also set up the System unit reference once all units are loaded and this hasn't happened yet (because all contained units are already compiled)

To correctly generate the import library for a package we need to resolve the dangling external symbols of all units. For this each unit now stores which symbols it exported from another unit and it also stores all global and external assembler symbols it has (maybe this can be streamlined later on, but for now this works).

the defs and syms (recursively) referred by inline routines and by the WPO
info
o defs and syms are no longer added immediately to the module's deflist/
symlist, even if they are created as "registered". Instead,
"doregister=true" simply means "add it to the symbol table at the
top of the symtable stack"
o normally only when a sym/def is deref'ed, it gets added to the module
symlist/deflist and defid/symid gets a (unique) value
o in cases where we use(d) the defid to construct unique names within the
current module, you now have to call call the tdef.new unique_id_str()
method. If the def was not yet registered, we will reserve room for it
in the deflist (to get a unique id), but the defid gets set to a
negative value computed from its position in the deflist. Should it
have to be written to the ppu file later on, the defid will be
modified to the actual position in the deflist. For both values,
new unique_id_str() will return the same result so that references
to this def before and after actual registrations are the same (needed
for the JVM backend, but also a good principle in general)
Overall: don't directly use symid/defid anymore to get unique identifiers,
but use tdef.new unique_id_str() instead (if necessary, a similar routine
for tsym can be added)
The result is the ppu file size gets reduced significantly after its big
increase as a result of the high level typed constant builder (which creates
a lot of defs). The result is even more efficient than before, as other
unneeded defs/syms from the localsymtables don't get saved/restored anymore
either.

o the maintenance effort will be less - previously we had to test 4
combinations:
tiny program with tiny rtl
tiny program with small rtl
small program with tiny rtl
small program with small rtl
I only tested both tiny and small programs with the small rtl, so I missed
a bug, which caused small programs built with the tiny rtl to always give
a "Nil pointer assignment" error. Now we only need to test two cases:
tiny program with tiny rtl
small program with small rtl
o I'm planning a bug fix for interrupt procedures in the tiny model, which
will make their prolog differ between small and tiny. Currently, they're
not used in the rtl, but that may change. And even if it doesn't,
interrupt procedures may also be used by user units.
git-svn-id: trunk@27516 -
The cause of the internal error was the following:
We have a generic in an unit ("A") which uses another unit ("B") in the implementation section and this other unit uses unit A in the interface section. Now the generic is specialized in the interface section of B. This leads to the problem that in unit A when it tries to load the globalsymtable of unit B that globalsymtable will be Nil, because parsing of the interface section is not yet finished. Thus the change in pgenutil.pas, specialization_init: if the unit is still "in_interface" the localsymtable needs to be used instead of the globalsymtable.
This doesn't necessarily lead to a compiling test though, as there is the following possibility:
Unit A contains a generic class/record (with methods) and uses unit B in the implementation section. This unit B also contains a generic class/record (with methods) and uses unit A in the implementation section. Both units contain a specialization of the other unit's generic outside of it's own generics (such that generate_specialization is fully triggered). Let's assume compilation starts with unit A and we reach the uses of unit B. Now compilation switches to unit B and completes as unit A is already registered and in compilation. The problem now is that the generic in unit A still contains unresolved forward declarations as the implementation section of A was not yet parsed which will lead to "forward declaration not solved" errors (Note: Delphi compiles this).
The solution to this is the following: if a generic is specialized from another unit which is not in state ms_compiled then the unit of the specialization needs to wait for the unit of the generic. So the specialization's unit adds itself into a list of waiting units of the generic's unit. Now inside "proc_unit" we need to check whether this module is waiting for other modules and if so avoid "finishing" the unit (which means generating the methods of the specialization, generating assembler code and ultimately freeing the scanner and PPU). Now when the generic's unit finishes we need to check whether other modules are waiting for it and finish them (of course it's a bit more complicated in reality, but that pretty much sums it up).
+ globstat.pas: Added an unit which handles the saving and restoring of the global state which was originally inside "parser.pas, compile" so that Don't Repeat Yourself (DRY) is respected.
* fmodule.pas, tmodule:
+ add fields to keep track of the units the module is waiting for and which modules are waiting for the module
+ add field for the saved global state (raw pointer to avoid circles)
+ add field for the state which is needed to finish the unit (raw pointer to avoid circles)
+ move the code which was used in "parser.pas, compile" after a module was successfully compiled to the new virtual method "end_of_parsing"
+ fppu.pas, tppumodule.end_of_parsing:
free the ppufile here
* pgenutil.pas:
+ add new procedure "maybe_add_waiting_unit" which adds the specialization's unit to the waiting list of the generic if that unit is not yet compiled
* generate_specialization: call the new function when we add a new (true) specialization
* specialization_init: instead of not adding implementation units at all check whether the unit is still parsing the interface section and add the localsymtable in that case
* pmodules.pas:
* change "proc_unit" to a function which returns "true" if the unit was already finished (no need to wait for other units)
+ move the code from "proc_unit" from "generate_specialization_procs" on to a new procedure "finish_unit" which
* this procedure is either called immediately in "proc_unit" if the unit does not need to wait for other units or from "finish_unit" itself if a unit that is waiting for the given unit does no longer wait for another module (special care is taken in proc_unit to avoid circles)
* parser.pas, compile:
* correctly handle the case if an unit is not finished
* use the new global state functionality from globstat.pas
* pay special attention when calling "set_current_module" (see comment at that call)
+ add tests from 22160
+ add test for above mentioned "diamond" case

cutting off long paths (no change in speed when compiling the compiler,
1% extra memory usage)
git-svn-id: trunk@21120 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1

This requires at least two passes of using wpo (first uses dead code

second pass uses this info to potentially further devirtualise).
I.e.:
1) generate initial liveness and devirtualisation feedback

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

* record all classrefdefs/objdefs for which a loadvmtaddrnode is generated,
and instead of marking all classes that derive from instantiated
classrefdefs as instantiated, only mark those classes from the above
collection that derive from instantiated classrefdefs as
instantiated (since to instantiate a class, you have to load its vmt
somehow -- this may be broken by using assembler code though)
