958600e74b * by default disable the warning about interfaces raising a particular
method's visibility, because this is common practice in Object-Pascal.
    It can be re-enabled with {$warn INTF_RAISE_VISIBILITY on} (mainly
    useful when trying to keep code compatible with the JVM target)

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler
that deal with paths/filenames with TPathStr (= ansistring) to prevent
    cutting off long paths (no change in speed when compiling the compiler,
    1% extra memory usage)

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

7aa3b99fb5 + -CN/{$CHECKLOWADDRLOADS+/-} switch to enable explicit checks for accesses
to low addresses in case the target cpu/OS does not support this (enabled
    for reads on AIX/PPC because on AIX the first 16KB are readable)

0d5b2b84a8 + Android/JVM target, including a translation of the Android r14 SDK
(= Android 4.0) java headers: java.*, javax.*, org.*, junit.*, android.*).
    The RTL can also be used to target earlier versions of the Android
    platform, but you manually have to take care of not using APIs that
    weren't available yet. Adding separate units for separate platform
    versions would only partly solve the problem, because some of the
    classes used inside the system unit have also changed across
    versions.

    Use -Tandroid while compiling to select the Android OS as target
    platform.

26f66897cd compiler:
- warn if compiler finds implicit or explicit string type conversion from a form of ansi string to a form of unicode string and vice versa
  - mark explicit warnings as OFF by default
  - warn if compiler finds an assignment of an unicode char const to ansi string or char type (warn for assignment of unicode string const to be implemented)
  - revert a piece of code from r19457 regards shortstring handling because shortstring handling should not differ from ansistring in this paticular case

f96f5f9e94 + {$VARPARACOPYOUTCHECK+/-} / -Cv switch to enable checking
var-parameters on the JVM target for changes to the value passed
    as var-parameter during the function call (because they are handled
    via copy-in/copy-out, this may indicate unexpected bahviour later on).

    out-parameters are checked in the same way, except if the out-parameter
    is a local variable because then reading it before the call may result
    in a bytecode verification error (since the variable may not yet be
    initialized)

0700e2d7ef + support for {$namespace x.y.z} directive to specify the namespace
for the current unit and all types/routines declared in it. The
    unit itself becomes a member of this namespace as well, so in
    case it's called unit1, it will be x.y.z.unit1, and type tclass
    declared in it will be x.y.z.tclass. Only used for the JVM
    target currently

e5920bc2b8 * delay verbosity changes just like localswitches changes
* store a node's verbosity in the node so that e.g. disabling warnings
    also disables warnings for this node in pass_1
   (the above together fix mantis #12076)
  * save/restore verbosity with {$push}/{$pop} (mantis #12075)
  * if warnings/notes/hints are turned off, also do not count encountered
    ones for the totals (otherwise -Sew cannot be used properly in
    combination with {$warnings off}, because disabled warnings will still
    trigger a compiler error) -- this required adding -vw/-vn/-vh to all
    tests using -Sew/-Sen/-Seh
  - removed some superfluous state saving/restoring from firstpass()

21abdd2f4e + support for specifying the minimal precision for floating point
constants. The default is currently 32 bits/single, which corresponds
    to the old behaviour (constants which cannot be exactly represented
    in the default/chosen precision will also still be automatically
    upgraded to higher precision). Supported constructs:
   * Command line switch -CF<x>
   * Compiler directive {$MINFPCONSTPREC <x>}
  whereby in both cases <x> can be default, 32 or 64. 80 is not supported
  because there is no generic way to figure out whether the current target
  actually supports 80 bit precision floating point calculations while
  parsing the command line switches (pbestreal can still change in case of
  win64 or -Cfsse2)
