typeconversion handling
+ support for class reference types in the JVM (although without class virtual
methods, they're not that useful)
git-svn-id: branches/jvmbackend@18516 -
cannot insert typecasting checks on the assignment side, only on the
values that are being assigned
o since valid_for_assignment() is called in tassignmentnode.typecheckpass()
after typecheckpassing left and right, moved the conversion of the
typecheck nodes into JVM-specific constructs from typecheckpass to
pass_1, so that they can use the information whether they are on
the assignment side or not
* forbid casting a child type to a parent type on the assignment side on
managed platforms, because that circumvents the type checking
git-svn-id: branches/jvmbackend@18515 -
o moved several routines from pmodules to ngenutil and overrode them
in njvmutil (for unit initialisation tables, resource strings, ...)
o force the evaluation stack size to at least 1 for the main program,
because the unit initialisation triggers are inserted there afterwards
and they require one stack slot
git-svn-id: branches/jvmbackend@18507 -
separate helper per array element type because there is no generic array
type, and we need to get the length of the arrays
git-svn-id: branches/jvmbackend@18501 -
only JVM constructs that are already implemented, but also ones that
will be supported in the future but that aren't implemented yet (to
make it easier to already adapt code to the future changes)
git-svn-id: branches/jvmbackend@18498 -
because creating a new scanner sets the block_type back to bt_general
(while we want to inject something in the current context)
git-svn-id: branches/jvmbackend@18493 -
current class, since constructors are not automatically inherited in
Java
o tprocdef.getcopy() implementation, which returns an (unfinished) copy
of a tprocdef. Finalise by calling symcreat.finish_copied_procdef()
o made it possible to specify an existing procdef as argument to
read_proc(), in which case it won't try to parse a procedure declaration,
but only a body and associate it with the passed procdef. This is
required for the inherited constructor support, since we cannot generate
a textual representation of inherited constructors that is guaranteed to
parse in the context of the current unit (e.g., if they use types from
a unit that is not in the uses clause of the current unit)
o folded tprocsym.find_procdef_bypara_no_rettype() into
Tprocsym.Find_procdef_bypara, by interpreting specifying nil as
retdef as not having to check the return def (required to compare
parent constructors with child constructors to see whether they
match, since the returndef will always be the current class type)
git-svn-id: branches/jvmbackend@18488 -
the types as declared in the system unit, since they can also be
used with equivalent but different types (e.g., byte vs shortint)
git-svn-id: branches/jvmbackend@18487 -
handles modifiers and adds the procdefinition. This code was
duplicated in several places (for objects and records)
* properly handle introducing artificial class constructors
(the manually constructed procdefs were wrong, now use
str_parse_method_dec)
