ce88df680b + symansistr conditional define that, when activated, makes the symbol/
mangled name handling ansistring rather than pshortstring based (required
    for JVM target; little effect on speed, some extra memory usage)

8fa42c206f + support for nested procedures for the JVM target
o since the JVM target has no stack/framepointer that can be passed
     on to nested routines, all local variables and parameters accessed
     from nested routines are grouped into a local record whose address
     is passed to nested routines. The same technique is also required
     for LLVM in the future

1795eff237 + support for emiting "signature" attributes for fields and methods; these
are JVM annotations used by Java's generics support. They cannot be used
    for FPC's generics support, but they are useful in other cases
  * emit classrefdefs as java.lang.Class, with a signature annotation that
    indicates which class they actually refer to

f27ebf8b6d + explicitly add constructors of parent class that do not appear in the
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)

40e0b4677a + support for (only named, for now) records in the JVM target:
implemented via classes, all descending from system.FpcBaseRecordType
    (records are also considered to be "related" to system.FpcBaseRecordType
     on the JVM target)
  * several routines are auto-generated for all record-classes: apart
    from a default constructor (if there is none), also clone (which
    returns a new instance containing a deep copy of the current
    instance) and deepCopy (which copies all fields of one instance
    into another one)
   o added new field "synthetickind" to tprocdef that indicates what
     kind of synthetically generated method it is (if any), and
     mark such methods also as "synthetic" in the JVM assembler code
   o split off the JVM-specific parser code (e.g., to add default
     constructors) into pjvm.pas

0d9948a61b + tprocsym.find_procdef_bypara_no_rettype() that looks for a procdef
based on the parameters, but ignoring the result type. Used to
    find out whether a function/procedures with these parameters
    can still be added in terms of overloading (since overloading
    ignores different result types, it only depends on the parameters)

019ca93a04 * symcreat functionality to use the parser from inside the compiler for
artificially generated stuff rather than directly working with defs/syms
   problems
    o scanner state saving/restoring, and avoiding problems in case of
      errors in the injected strings
    o in case of the actual application (adding overriding constructors):
      the parameters may be of types not visible in the current unit to
      newly written code -> can't just use the scanner...

002455ab5c + support for instance and class fields, and unit-level global variables
o hlcgobj support in tcgsubscriptnode.pass_2 for JVM-required functionality
   o slightly different handling for class fields for the JVM than for other
     platforms: instead of adding a unit-level staticvarsym with a hidden name,
     rename the original (unused) field and add the staticvarsym with the original
     name to the object symtable. This is required because the JVM code generator
     has to know the class the field belongs to, as well as its real name
   o moved tprocdef.makejvmmangledcallname() functionality mostly to
     jvmdef.jvmaddtypeownerprefix() because it's also required for mangling
     field symbol names
  * changed the interface of jvmdef from ansistring to shortstring because
    all of its results are also used in shortstring contexts (and they're
    unlikely to overflow the shortstring limit)
  * "protected", "private" (without strict) and implementation-only symbols
    now get "package" visibility instead of "public" visibility

57bd6d2685 + merged nestedprocvars branch
+ support for nested procedural variables:
    o activate using {$modeswitch nestedprocvars} (compatible with all
      regular syntax modes, enabled by default for MacPas mode)
    o activating this mode switch changes the way the frame pointer is
      passed to nested routines into the same way that Delphi uses (always
      passed via the stack, and if necessary removed from the stack by
      the caller) -- Todo: possibly also allow using this parameter
      passing convention without enabling nested procvars, maybe even
      by default in Delphi mode, see mantis #9432
    o both global and nested routines can be passed to/assigned to a
      nested procvar (and called via them). Note that converting global
      *procvars* to nested procvars is intentionally not supported, so
      that this functionality can also be implemented via compile-time
      generated trampolines if necessary (e.g. for LLVM or CIL backends
      as long as they don't support the aforementioned parameter passing
      convention)
    o a nested procvar can both be declared using a Mac/ISO Pascal style
      "inline" type declaration as a parameter type, or as a stand-alone
      type (in the latter case, add "is nested" at the end in analogy to
      "of object" for method pointers -- note that using variables of
      such a type is dangerous, because if you call them once the enclosing
      stack frame no longer exists on the stack, the results are
      undefined; this is however allowed for Metaware Pascal compatibility)

0cfc6e1cac + support for "univ" in macpas mode: a parameter modifier that allows
passing any value to that parameter which has the same size as the
    parameter (it basically acts as if there is an explicit type conversion
    to the parameter type around the value at the caller side). If a procvar
    has an univ parameter, all procvars whose corresponding parameter
    has the same size as that univ parameter are similarly compatible.

    This transparent compatibility can however cause crashes in case of
    of the procvars when one of the types is passed on the stack and the
    other isn't (because then the called routine will a) load the parameter
    from a wrong location and b) pop the wrong amount off of the stack at
    then end). Therefore FPC will warn in most cases where this can happen.

d1538ab023 o added ARM VPFv2/VFPv3 support:
+ RTL support:
      o VFP exceptions are disabled by default on Darwin,
        because they cause kernel panics on iPhoneOS 2.2.1 at least
      o all denormals are truncated to 0 on Darwin, because disabling
        that also causes kernel panics on iPhoneOS 2.2.1 (probably
        because otherwise denormals can also cause exceptions)
    * set softfloat rounding mode correctly for non-wince/darwin/vfp
      targets
    + compiler support: only half the number of single precision
      registers is available due to limitations of the register
      allocator
    + added a number of comments about why the stackframe on ARM is
      set up the way it is by the compiler
    + added regtype and subregtype info to regsets, because they're
      also used for VFP registers (+ support in assembler reader)
    + various generic support routines for dealing with floating point
      values located in integer registers that have to be transferred to
      mm registers (needed for VFP)
    * renamed use_sse() to use_vectorfpu() and also use it for
      ARM/vfp support
    o only superficially tested for Linux (compiler compiled with -Cpvfpv6
      -Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
      the fpu exception handler still needs to be implemented), Darwin has
      been tested more thoroughly
  + added ARMv6 cpu type and made it default for Darwin/ARM
  + ARMv6+ implementations of atomic operations using ldrex/strex
  * don't use r9 on Darwin/ARM, as it's reserved under certain
    circumstances (don't know yet which ones)
  * changed C-test object files for ARM/Darwin to ARMv6 versions
  * check in assembler reader that regsets are not empty, because
    instructions with a regset operand have undefined behaviour in that
    case
  * fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
    int64->single type conversion
  * fixed constant pool locations in case 64 bit constants are generated,
    and/or when vfp instructions with limited reach are present

  WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
    code with -Cparmv6 (or higher), or you will get crashes. The reason is
    that storing/restoring multiple VFP registers must happen using
    different instructions on pre/post-ARMv6.
