pasbool8type for this results in too much trouble (we mustn't use i1
for parameters, because then LLVM will try to apply the ABI convention
for passing "1 bit" values, or in records because then this may
result in unwanted bitpacking). Downside: the new LLVMBool1 type is
also exposed in the system unit, because we need it to define LLVM
intrinsics...

Extract functionality that is shared between the metadata files for units (PPU) and for packages (PCP) into a parent class called tentryfile
+ add new unit entfile which contains the new tentryfile class and related types and constants
* ppu.pas:
- remove methods, fields, types and constants which were moved to entfile.pas
* replace the parts of tppuheader shared with tentryheader by a field of type tentryheader
fppu.pas, pmodules.pas, utils/ppumove.pp, utils/ppuutils/ppudump.pp:
+ add entfile to uses
* adjust access to common header fields

reusable defs for defs in exceptionsymtables, or indeed use any defs from an
exceptionsymtable in the high level code generator, as those defs are freed
before the module is completely compiled -> crashes while trying to use them
in the assembly writing phase ->
o when the symtablestack top is an exception symtable, keep looking for
another symtable to put the def in
o give an internalerror if we encounter a def in an exceptionsymtable anyway
in getreusablesymtab

an exception symtable (then the new def cannot be safely made reusable,
as the exception symtable may be freed before the module is completely
compiled)

"don't free even if not registered"; use for defs that may not be written
to a ppu file, but that must nevertheless survive the compilation of the
current module
* mark all defs created for para locations as "don't free even if not
registered", because we don't discard and recalculate all para locations
after a module has been compiled (since that's not needed)
o solves issues if the paralocations for a routine in the interface of
unit A are calculated while the implementation of unit B gets
compiled, and a new reusable type is allocated at that point which
is not used anywhere else (after r32160)

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.
git-svn-id: trunk@32153 -
don't need a separate field for this
o changed the order in which symid and realname are stored to/loaded from
the ppufile (because tsym.create now initialised tsym.symid, and it's
called from ppuload) -> increased ppu version
