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.

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

relocations for addr_pic_no_got references (do not go via the GOT)

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)

the system unit's errno variable (it's an implementation-only variable)

+ added regtype and subregtype info to regsets, because they're
also used for VFP registers (+ support in assembler reader)

* don't use r9 on Darwin/ARM, as it's reserved under certain

* changed C-test object files for ARM/Darwin to ARMv6 versions
* check in assembler reader that regsets are not empty, because

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.

+ initial implementation of whole-program optimisation framework
+ implementation of whole-program devirtualisation
o use:
a) generate whole-program optimisation information (no need
to completely compile the program and all of its units
with -OW/-FW, only the main program is sufficient)
fpc -OWdevirtcalls -FWmyprog.wpo myprog
b) use it to optimise the program
fpc -B -Owdevirtcalls -Fwmyprog.wpo myprog
(the -B is not required, but only sources recompiled during
the second pass will actually be optimised -- if you want,
you can even rebuild the rtl devirtualised for a particular
program; and these options can obviously also be used
together with regular optimisation switches)
o warning:
- there are no checks yet to ensure that you do not use
units optimised for a particular program with another
program (or with a changed version of the same program)

"class of x" has been instantiated rather than a
"class of tobject". this required storing the instantiated
classrefs in their own array though, because at such a
point we don't have a "class of x" tdef available (so

+ symbol liveness wpo information extracted from smartlinked programs
(-OW/-Owsymbolliveness)
+ use symbol liveness information to improve devirtualisation (don't
consider classes created in code that has been dead code stripped).
This requires at least two passes of using wpo (first uses dead code
info to locate classes that are constructed only in dead code,
second pass uses this info to potentially further devirtualise).
I.e.:
1) generate initial liveness and devirtualisation feedback
fpc -FWtt.wpo -OWall tt.pp -Xs- -CX -XX
2) use previously generated feedback, and regenerate new feedback
based on this (i.e., disregard classes created in dead code)
fpc -FWtt-1.wpo -OWall -Fwtt.wo -Owall tt.pp -Xs- -CX -XX
3) use the newly generated feedback (in theory, it is possible
that even more opportunities pop up afterwards; you can
continue until the program does not get smaller anymore)
fpc -Fwtt-1.wpo -Owall tt.pp -CX -XX
* changed all message() to cgmessage() calls so the set codegenerror
* changed static fsectionhandlers field to a regular field called
fwpocomponents
* changed registration of wpocomponents: no longer happens in the
initialization section of their unit, but in the InitWpo routine
(which has been moved from the woinfo to the wpo unit). This way
you can register different classes based on the target/parameters.
+ added static method to twpocomponentbase for checking whether
the command line parameters don't conflict with the requested
optimisations (e.g. generating liveness info requires that
smartlinking is turned on)
+ added static method to twpocomponentbase to request the
section name

* Fixed compilation of resource, which is included in a unit located in different folder than main source.
* .res files must be copied to units output folder, otherwise .res files will not be found when only compiled units path is available and compiler does not know anything about sources folder.
* Improved resource related error messages.

git-svn-id: trunk@10481 -
is <> 0 (Delphi compatible now, + various tests)
+ support for enums and sets in is_in_limit()
* fixed converting smallset expressions to varsets
* improved choosing an appropriate common set type when mixing
set types in an expression
- removed no longer used normalset code from nadd.pas
- disabled large set (>256 elements) support for now, because
they are not yet supported entirely throughout the compiler
and this causes errors at run time in several situations
git-svn-id: trunk@8515 -
moved to it)
+ -go[no]dwarfsets switch to [disable]/enable generation of dwarf set
information, as this breaks gdb < 6.5 (used to be disabled in the
compiler by an ifdef, still off by default)
git-svn-id: trunk@8414 -
TOption.TargetDefines and call it before parsing the config file,
so extra defines like UNIX and WINDOWS are already defined while
parsing the config file (mantis #9450)
git-svn-id: trunk@8371 -
- {$intpromotion common_type} or -CIcommon_type switches to common type promotion.
- {$intpromotion native_integer} or -CIcommon_type switches to current behaviour.
- Default in tp mode is common_type, native_integer in other modes
- Compiler can cycle with -CIcommon_type
- Still needs checking on other architectures than i386
git-svn-id: trunk@8118 -
* varsets ({$packset x}) are now supported on big endian targets
* gdb now displays sets properly on big endian systems
* cleanup of generic set code (in, include/exclude, helpers), all
based on "bitpacked array[] of 0..1" now
* there are no helpers available yet to convert sets from the old to
the new format, because the set format will change again slightly
in the near future (so that e.g. a set of 24..31 will be stored in
1 byte), and creating two classes of set conversion helpers would
confuse things (i.e., it's not recommended to use trunk currently for
programs which load sets stored to disk by big endian programs compiled
by previous FPC versions)
* cross-endian compiling has been tested and still works, but one case
is not supported: compiling a compiler for a different endianess
using a starting compiler from before the current revision (so first
cycle natively, and then use the newly created compiler to create a
cross-compiler)
git-svn-id: trunk@7395 -
because on win64 the location of a function result can depend on its
size (so some chararrays had to be returned in registers and others
by reference, which means it's impossible to have a generic function
declaration which works in all cases) (mantis #8533)
* pad constant string assignments to chararrays with #0 up to the
length of the chararray for 2.0.x compatibility (fixes
tests/test/tarray3)
git-svn-id: trunk@6915 -
a target flag, since some kernels may be able to handle alignment
problems, and the alignment requirements may not be absolute (e.g. on
ppc64, only 8 byte values need alignment, and only to 4 byte boundaries)
-> linux/ppc64 has tf_requires_proper_alignment set in its target flags,
darwin/ppc64 hasn't
git-svn-id: trunk@6745 -
* fixed downsizing the precision of floating point values
* floating point constants are now treated using only the minimal
precision required (e.g. 2.0 is now a single, 1.1 extended etc)
(Delphi compatible)
git-svn-id: trunk@5927 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled
git-svn-id: trunk@5192 -
* turn off stackframe optimizations on x86 if get_frame is called
in the current routine, or if the address of a nested function
is taken in the current routine
+ test for the above
* this fixes the IDE when compiled with stackframe optimizations
on x86
git-svn-id: trunk@5146 -
allow runtime optimization if the destination is the
same as a source parameter
* tassignmentnode now sets aktassignmentnode global that can be used
to use the left node as a destination parameter and
skip the assignment
* disabled all cpu specific shortstr concat/append
