* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
their enum name, instead of number

labels of LOC_JUMP in the node's location. This generates some extra jumps
for short circuit boolean and/or-expressions if optimizations are off, but
with optimisations enabled the generated code is the same (except for JVM
because the jump threading optimisation isn't enabled there yet).
git-svn-id: trunk@31431 -
o sets of enums are handled as JUEnumSet instances, others as JUBitSet
derivatives (both smallsets and varsets, to make interoperability with
Java easier)
o special handling of set constants: these have to be constructed at run
time. In case of constants in the code, create an internal constsym to
represent them. These and regular constsyms are then aliased by an
another internal staticvarsym that is used to initialise them in the
unit initialisation code.
o until they are constructed at run time, set constants are encoded as
constant Java strings (with the characters containing the set bits)
o hlcgobj conversion of tcginnode.pass_generate_code() for the genjumps
part (that's the only part of the generic code that's used by the JVM
target)
o as far as explicit typecasting support is concerned, currently the
following ones are supported (both from/to setdefs): ordinal types,
enums, any other set types (whose size is the same on native targets)
o enum setdefs also emit signatures
o overloading routines for different ordinal set types, or for different
enum set types, is not supported on the JVM target
git-svn-id: branches/jvmbackend@18662 -
JDK class-style enums rather than plain ordinals like in Pascal
o for Pascal code, nothing changes, except that for the JVM target
you can always typecast any enum into a class instance (to interface
with the JDK)
o to Java programs, FPC enums look exactly like Java enum types
git-svn-id: branches/jvmbackend@18620 -
o support for ansistring constants. It's done via a detour because the
JVM only supports UTF-16 string constants (no array of byte or anything
like that): store every ansicharacter in the lower 8 bits of an
UTF-16 constant string, and at run time copy the characters to an
ansistring. The alternative is to generate code that stores every
character separately to an array.
o the base ansistring support is implemented in a class called
AnsistringClass, and an ansistring is simply an instance of this
class under the hood
o the compiler currently does generate nil pointers as empty
ansistrings unlike for unicodestrings, where we always
explicitly generate an empty string. The reason is that
unicodestrings are the same as JLString and hence common
for Java interoperation, while ansistrings are unlikely to
be used in interaction with external Java code
* fixed indentation

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 -
in a single statement, to be added later)
o the unicodestrings are internally simply java.lang.String instances
o at the language level, the unicodestrings are assignment-compatible
with java.lang.String
o constant strings can be implicitly converted to java.lang.String
o since java.lang.String is immutable, in particular changing a
single character in a string is extremely inefficient. This could
be solved by letting unicodestring map to java.lang.StringBuilder,
but that would make integration with plain Java code harder

that's how these operations also work on other architectures
* fixed tjvmaddnode.second_generic_compare() for this new order
git-svn-id: branches/jvmbackend@18338 -
in case of -ar add to the assembler output the height of the
evaluation stack every time it's increased or decreased (to
more easily track missing/wrong inc/decstack() operations)
git-svn-id: branches/jvmbackend@18335 -
u64bit division/mod, and no overflow checking for divisions
(none yet for add nodes either, but that has to be implemented
in hlcgcpu rather than in the add-nodes themselves)
