The result type of the intrinsic is determined by the Then-expression to provide a bit of control. There might however be some situations in which this fails, for this exceptions need to be added (e.g. a constant string needs to be converted to a normal string).
compinnr.inc:
+ add new constant in_ifthen_x_y_z for the IfThen() intrinsic
psystem.pas:
+ create_intern_symbols: add symbol for IfThen() intrinsic
pexpr.pas:
* statement_syssym: parse parameters of IfThen() intrinsic and return corresponding inline node
ninl.pas, tinlinenode:
+ new method handle_ifthen() which converts the inline node to an if-node which assigns the expressions to a temp node that is returned
* pass_typecheck: handle in_ifthen_x_y_z using handle_ifthen()
* pass_1: in_ifthen_x_y_z does not need a first pass as it's already converted after the typecheck pass
+ added tests

support for nested types when generating an access to a static fied;
we also always do that when generating the mangled name of a static
field declaration in symcreat.make_field_static() (mantis #29030)
git-svn-id: trunk@32517 -
+ new constant inline_specialization_block_types to easily keep track of block types in which inline specialization is allowed
pexpr.pas:
* use new inline_specializatio_block_types instead of a inline constant set
git-svn-id: trunk@32388 -
pexpr.pas, factor.factor_read_id:
* instead of using generate_specialization() use generate_specialization_phase1() and (for non-procdefs) generate_specialization_phase2
* pass generated specialization context for procdef on to the generated call nodes which do the second part of the specialization then
git-svn-id: trunk@32384 -
pexpr.pas:
+ new enum texprflag and corresponding set texprflags
* comp_expr: replace accept_equal and typeonly with texprflags parameter
* factor: replace typeonly and hadspecialize with texprflags parameter
* sub_expr: replace accept_equal and typeonly with texprflags parameter
* adjust calls to comp_expr(), factor() and sub_expr()
other units:
* adjust calls to comp_expr(), factor() and sub_expr()

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.

pexpr.pas:
* initialize srsym in the classrefdef case; it should not have let to problems, because it's only used if erroroutp1 is false which is only the case if the symbol is assigned, but better save then sorry...
git-svn-id: trunk@31887 -
* postfixoperators: generate specialize nodes in mode Delphi
* factor: don't call postfixoperators() if returned node is a specialize node
* sub_expr: handle specialize nodes
* sub_expr: extract common code handling specializations in < and as/is into a nested function
git-svn-id: trunk@31859 -
* extend handle_specialize_inline_specialization() with the ability to handle generic functions
* have handle_factor_typenode() and postfixoperators() make use of this extension
git-svn-id: trunk@31856 -
* extend parse_proc_head() with support for /parsing/ generic functions (at least in mode Delphi, mode ObjFPC depends on the new isgeneric parameter to be set)
* adjust parsing of interface mappings with a generic interface (note: in mode ObjFPC this now requires a "specialize" directly before the generic interface's name, which is more in line with other uses of "specialize")
pexpr.pas, factor:
* don't call postfixoperators() if hadspecialize is set
tests/test/tgeneric79.pp:
* adjust test to changed syntax
git-svn-id: trunk@31769 -
* extend do_member_read() with the possibility to pass a specialization context on to do_proc_call() if the symbol is a procsym
git-svn-id: trunk@31767 -
* do_proc_call can take a tspecializationcontext and pass it on to ccallnode.create()
Note: pointers to generic functions/methods are not yet supported, so there's a temporary, non-translated error message for these constructs
git-svn-id: trunk@31766 -
* extend tcallnode with the ability to pass a tspecializationcontext so that tcallcandidates can do a final specialization
* the final procdef is registered at the end of tcallnode.pass_typecheck
git-svn-id: trunk@31763 -
* for now all undefineddefs are created as registered
Note: an additional parameter instead of an overload is used for tundefineddef.create as otherwise both constructors would need to be overridden in potential descendant CPU-specific classes...

type
TTestLongInt = specialize SomeOtherUnit.TTest<LongInt>;
will now have to read as
type
TTestLongInt = SomeOtherUnit.specialize TTest<LongInt>;
While this is not backwards compatible this situation should arise seldomly enough and the benefits especially in context with generic functions/procedures/methods outway the drawbacks.
pbase.pas:
* try_consume_unitsym: add a allow_specialize parameter that allows to parse "specialize" in front of a non-unit symbol; whether it was a specialization or not is reported using a new is_specialize parameter
+ add a new overload try_consume_unitsym_no_specialize that calls try_consume_unit sym with allow_specialize=false and a dummy is_specialize parameter
* switch calls to try_consume_unitsym to try_consume_unitsym_no_specialize
pstatmnt.pas, try_statement:
* switch call to try_consume_unitsym to try_consume_unitsym_no_specialize
* adjust call to parse_nested_types
ptype.pas:
+ extend id_type with the possibility to disallow unit symbols (needed if a specialize was already parsed) and to report whether a specialize was parsed
+ extend parse_nested_types with the possibility to tell it whether specializations are allowed
* have parse_nested_types specialize generic defs if one is encountered and local type defs are allowed
* id_type: only allow "unitsym.specialize sym" or "specialize sym", but not "specialize unitsym.sym"
* single_type: correctly handle specializations with "specialize" keyword
* read_named_type.expr_type: there is no longer a need to check for "specialize" keyword
pexpr.pas:
+ new function handle_specialize_inline_specialization which tries to specialize a type symbol
* handle_factor_typenode: handle specializations after a point that follows a record or object (why isn't this part of postfixoperators anyway? O.o)
* postfixoperators: handle "specialize" after records and objectdefs
* factor_read_id: handle "specialize" in front of an identifier (and after unit symbols)
+ added tests
* adjusted test webtbs/tw16090.pp

Please note that this warning won't be triggered if an instance of that class is created using a class variable of that class type as the compiler can not know the type contained in the variable at compile time (see also the added test).
+ msg/errore.msg: added disabled message which informs about the instantiation of an abstract class
* pexpr.pas, do_member_read: generate the message if we have a constructor call for an abstract class using a loadvmtaddrnode (thus the type name is used and not a class variable)
* msg{idx,txt}.inc: updated
+ added test

pbase.pas:
+ add an overload for identifier_not_found for which the file position can be supplied
pexpr.pas, factor_read_id:
* store the file position before reading the identiifer token
* use the new identiifer_not_found overload to explicitely set the file position
* set the file position of the created node
git-svn-id: trunk@27947 -
* ptype.pas, id_type:
generate the "identifier not found" message only if the identifier was really not found and not when the identifier is a non-type
* pexpr.pas, statement_syssym:
don't generate the "type id expected" error message for Default() anymore; this is already handled by single_type
+ added test (though this again will not help much as output is not parsed...)
