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.

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

* for now all typesyms are created as registered
Note: an additional parameter instead of an overload is used for ttypesym.create as otherwise both constructors would need to be overridden in potential descendant CPU-specific classes...
git-svn-id: trunk@31591 -
+ add an overload of check_hints() that allows to specify the current file position
* have the previous check_hints() procedure be an inline procedure as it simply calls the new overload

llvm
* instead, add LLVM-specific name mangling based on the asmsymbol's bind
and typ whenever we write out its name

o only create an accessor wrapping the inherited accessor at a
potentially lower visibility level if the overriding property
itself does not specify a different accessor to use
o simplified code
o tests

+ Test.
+ Check duplicate labels in assembler blocks. This was impossible due to above bug and duplicate labels were detected only at assembling stage where no location information could be provided.
git-svn-id: trunk@27472 -
symsym.pas, tfieldvarsym:
+ add new field fieldvarsym which holds a reference to a tfieldvarsym if the static sym was created based on such a symbol
+ add necessary methods and code to correctly load from and store to PPU
+ add new constructor create_from_fieldvar
symcreat.pas, make_field_static:
* use new create_from_fieldvar constructor instead of the default one
hlcgobj.pas, finalize_static_data:
* check whether the static var is based on a generic's class var
ppu.pas:
* increase PPU version
+ added test

specific descendent classes and moved the code that deals with this in the
code generator also to target-specific classes -> only ifdefs left in

override them safely in subclasses to add more data (they finalise
writing their ibentry)
* removed "virtual" from all ppuload constructors for similar reason
as above
+ added virtual (empty) ppuwrite_plaform() method that is called from
tstoreddef/tstoredsym.ppuwrite(), which can be safely overridden in
child classes to add extra data (called centrally from a new
tstoreddef/sym.writeentry() method)
+ added virtual (empty) ppuload_platform() method that is called from
tstoreddef/tstoredsym.ppuload(), which can be safely overridden in
child classes to read the extra data (unfortunately cannot be called
from one single location, and these calls had to be added for each
generic subclass separately)
git-svn-id: trunk@27378 -
o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls

for llvm, and empty for other targets:
o the '@' is required to mark a global/static symbol identifier in llvm
o the double quotes are required in case special characters are involved
o the \01 means that the name should not be mangled by llvm (e.g., by
default it still adds the C-prefix to all symbol names, and replaces
some special characters with alternatives)
* apply this prefix/suffix in all name mangling routines

that contains their mapping to LLVM (mainly getting rid of variant parts
and adding explicit padding when not using {$packrecords c})

-CTlowercaseprocstart
o convert all consecutive uppercase characters at the start to lowercase
instead of only the first one. Exception: if there is more than one
such character and the last one is followed by a lowercase character,
assume the last uppercase character belongs to the second word (like
in FPCIsGreat) and don't lowercase that one
