- i386/cgcpu.pas: removed segment check, rejecting references with segment here is too early. These references are passed to tcgx86.a_loadaddr_ref_reg, which can generate required code for them (or reject if they are not allowed for the target).
- ncgld.pas: removed "not tf_section_threadvars in target_info" condition, it is inverse to one on the following line, making non-generic branch impossible to execute.
+ Define FPC_SECTION_THREADVARS macro if corresponding flag is set for the target.

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

default values
o pass on this version setting on to the Darwin linker
o use this setting to determine which version of the startup code (crt1.o

When arguments are temps, they are supposed to be released by tcgcallnode.release_para_temps. However, taking address with taddrnode effectively changes original location of temp to some LOC_REGISTER, tcgcallnode.release_para_temps no longer sees the original location and therefore does not free such temps.

(= 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.

+ -CTcompactintarrayinit command line option to change the code generation
for typed array of some kind of integer-type initialization so that it
takes up less space in the bytecode (because the bytecode for all
routines, including the class initialization code that contains the
typed constant init code, is limited 64kb, large array or multiple
array constants could fairly easily bump into that limit)

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)

val/str for enums for now) for the JVM target: insert/delete/pos/...
* use generic unicodestring helper routines where possible for the JVM
target (not that many as for shortstrings since unicodestring is
handled using java.lang.String)
+ complete widestring manager implementation for the JVM target. It uses
a class with virtual methods rather than a record with function pointers
for speed reasons though (since no existing widestring manager will be
compatible anyway, that shouldn't cause any problems)
git-svn-id: branches/jvmbackend@18882 -
* converts the embedded information into controller specific records (arm and avr)
* new cpu-specific units for several Stellaris (Fury and Tempest class) targets,

git-svn-id: trunk@18848 -
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
git-svn-id: branches/jvmbackend@18746 -
+ 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)
git-svn-id: branches/jvmbackend@18286 -
* ensure that all defines are written when running the compiler with -va

git-svn-id: trunk@17469 -
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)

git-svn-id: trunk@14912 -
+ 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.
