unicodestring = java.lang.String. The reason this was the default in
the past is that this was the first string type that was implemented,
and without it being the default most code involving string operations
would fail. Now the default strings types are the same as for other
targets
+ new {$modeswitch unicodestrings} directive, that when activated
*together* with {$h+},
1) changes char into an alias for widechar
2) changes string into an alias for unicodestring
3) changes the preferred string evaluation type (in case of uncertainty)
to unicodestring
{$modeswitch unicodestrings} with {$h-} does not change anything at all
regarding the string type (it still changes the char type)
+ new uuchar unit that redefines char as widechar, and which is automatically
included by the compiler if {$modeswitch unicodestrings} is enabled

in the system unit for easier debugging)
* disabled a bunch more feature flags by default for the JVM target
* incorporate modified version of inc/systemh.inc (split into two parts:
jsystemh_types.inc and jsystemh.inc, because some of the types are
required for the declaration of the shortstring/ansistring/set/...
classes, which in turn are required for the routine declarations) and
inc/system.inc (as jsystem.inc)
o moved some routines around from old to new locations based on where
they appear in the common files
o added a number of defines that allow skipping more common implementations
in case a platform-specific one is already available
* all base classes (AnsistringClass etc) are now descendants of
JLObject rather than TObject, because their declaration is now parsed
before TObject is known (and there's no need for them to inherit from
TObject)
* incorporate modified version of inc/system.inc
* use the common version of generic.inc, currh.inc, gencurr.inc and
genmath.inc (with small modification to those files)
+ addition of quite a bit of system unit functionality (halt, runerror,
random, round, str() for integer types, abs, odd, endian swapping helpers,
bit scanning, trigonometric functions, ln, exp, ...)
o round()/trunc() for comp-types has been renamed trunc_comp() on the
JVM target because their JVM signature conflicts with trunc(currency)
o the unsigned versions of swapendian() and other endian helpers are not
available on the JVM target because of JVM signature conflicts

+ it_interfacejava type (not explicitly selectable via -SI nor
{$interfaces xxx}, but default for jvm target)
* disable it_interfacecom/corba for jvm target
+ init_settings for jvm that select it_interfacejava as default interface
type
+ default_class_type constant (in symconst) that is odt_javaclass for the jvm
target and odt_class for other targets (used to determine the meaning of
"type x = class" declarations)

* ensure that all defines are written when running the compiler with -va
* even if a define is defined/undefined, write a message if it is written again
git-svn-id: trunk@17714 -
* TCmdStr changed into an ansistring
* command line parameter handling uses now ansistrings
* message handling parameters are now ansistrings

relocations for addr_pic_no_got references (do not go via the GOT)
* fixed code generator so that it generates addr_pic_no_got references
also for platforms that use the internal assembler (this will break linking
of some tests that check static data > 2GB on Linux/x86-64, but they were
already broken before as well because we don't use the "huge" x86-64
execution model)
* fixed x86-64 Linux syscall code to not expect GOT-based relocations for
the system unit's errno variable (it's an implementation-only variable)

+ 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.
