future use by high level code generator targets
o this in turn required that all a_load*_loc* methods are called via
hlcg rather than via cg, since a location can be a subsetref/reg and
and those are no longer handled in tcg
o that then required moving several force_location_* routines into
thlcg because they use a_load_loc*, but did not take tdef size
parameters (which are required by the thlcg a_load_loc* routines)
o the only practical consequence is that from now on, you have to
use hlcg.location_force_mem/reg() (fpureg not yet) and
hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
might be involved

on AIX due to the extra inserted local symbols (although in case e.g
multiple procedures contain a typed constant with the same name, only
one can be accessible)
* removed '.' suffix of local symbols inserted for debug info of typed
constants for AIX (gdb couldn't find those symbols; it seems the
address calculated by gdb for typed constants is still not correct
though)

assume that all virtual methods that can be called via interfaces that
appear in the program are in fact called (fixes WPO when applied to
MSEIDE)
git-svn-id: trunk@20952 -
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
git-svn-id: branches/jvmbackend@20887 -
support the stabx as understood by gdb, which is a mixture of regular
stabs and stabx (e.g., class/object definitions are completely different
in real stabx). This means that gdb can be used to debug aix programs,
but the native dbx will complain about lots of debug information
constructs
git-svn-id: trunk@20842 -
hence contains a dummy "main" that refers to the system unit
FPC_SYSTEMMAIN, which in turn jumps to the main program's PASCALMAIN
* we call FPC_SYSTEMMAIN instead of jumping to it like on Darwin, so that
the TOC gets set correctly

in LOC_CMMREGISTER, not in LOC_CFPUREGISTER (and they also are there in
case the softfp calling convention is used), and this change broke SPARC

o new eabihf (hard float) abi
o vfpv3_d16 variant of VFP (default variant used by EABI assemblers: VFPv3
with only 16 double registers instead of 32) and pass it to GNU as
o make the odd numbered single precision floating point VFP registers
available for explicit allocation for use by the calling convention
* fixed copy/paste error in stdname of S30 register
-> use -dFPC_ARMHF to create an ARM eabi hard float compiler
(mantis #21554)

in code and not in constants. In the case of primitive types constant nodes
are used while complex types like arrays, records and objects use a local
variable which is initialized to zero once at the entry of the method (the
variable is reused if Default() is used for the same type multiple times in
the same method). For this a new compilerproc was added which uses FillChar
to initialize the given memory area to zero.
This fixes Mantis #9420.
+ psystem.pas: Added Default symbol to system unit
+ htypechk.pas: Added function "is_valid_for_default" which checks recursively
whether the given type can be used with Default at all.
Forbidden types are files, helpers, ObjC and C++ types. This
check is used for records, arrays and objects only if the mode
is a non-Delphi one, as Delphi ignores these types on lower
levels.
+ msg/errore.msg: Added error message for unsupported types for Default()
+ symconst.pas: Added a new enum value vo_is_default_var which is used for the
local variables utilized by Default() so their initalization
and finalization can be avoided.
+ pexpr.pas: Add handling of Default() intrinsic to "statement_syssym"
+ ninl.pas: Extended tinlinenode by a method which returns the correct node for
a Default() and used that method in handle_typecheck.
* ncgutil.pas: Check for new flag "vo_is_default_var" when initializing and
finalizing local variables.
* ppu.pas: increase PPU version
+ psub.pas:
* Added a new routine which zeros defaultvars of a symtable.
* Use this routine inside "initializevars".
* Also use this routine to initialize the staticsymtable of the unit/program.
* Adjusted ppudump, because of the new enum value.
+ Added implementation of fpc_zeromem to system unit.
+ Added tests for Default()
git-svn-id: trunk@20629 -
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.
As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.
git-svn-id: trunk@20119 -
* converts the embedded information into controller specific records (arm and avr)
* new cpu-specific units for several Stellaris (Fury and Tempest class) targets,
+ STM32F103RB
- old Stellaris unit has been removed

and initialise global variables that are wrapped (records, arrays)
in those sections
o check whether pd.localst is assigned in dbgjasm, because it's
not for the unit initialisation routine
o moved insertbssdata() from ncgutil to ngenutil and override it
njvmutil (it does nothing in the latter, since global variables
are added as fields to the class representing the unit; the
initialisation is done in gen_initialize_code() in thlcgjvm)
o added force_init() and force_final() methods to ngenutil, so
that targets can force init/final routines separate from the
regular managed types infrastructure (used by JVM for forcing
an init section in case of records/arrays)
git-svn-id: branches/jvmbackend@18460 -
hlcgobj so it can be overridden with target-specific code (e.g.,
the JVM target has to add initialisation code to allocate regular
arrays and records in constructors and unit/program initialisation)

svn r17068,17071,17081,17136
* changed all init_paras code in both thlcgobj and ncgutil to use
location_get_data_ref() instead of direct a_load_loc_reg()/
ref.base:=reg so it also works with the JVM target
* changed all init_paras code so it works with targets that do
not pass an implicit high parameter for open array (and a similar
fix in ncgcal)
+ added support for initializing array (both regular and open)
"out" parameters of reference counted types on the JVM target
(the arrays will be initialised with nil rather than an empty
array for implementation reasons, see comments in compproc.inc)
* factored out calling of functions in the system unit directly
from hlcgobj
git-svn-id: branches/jvmbackend@18421 -
o support for copying value parameters at the callee side if they were
passed by reference in hlcg
o JVM g_concatcopy() implementation for arrays
o moved code to get length of an array from njvminl to hlcgcpu so it can
be reused elsewhere as well
o export array copy helpers from system unit for use when assigning one
array to another
o some generic support for types that are normally not implicit pointers,
but which are for the JVM target (such as normal arrays)
* handle assigning nil to a dynamic array by generating a setlength(x,0)
node instead of by hardcoding a call to fpc_dynarray_clear, so
target-specific code can handle it if required
* hook up gethltemp() for JVM ttgjvm so array temps are properly
allocated
git-svn-id: branches/jvmbackend@18388 -
nutils.pas into virtual class methods of a new tnodeutils class defined
in ngenutil (global factory: cnodeutils), so they can be overridden by
architecture-specific implementations (required by the JVM backend)

since the definition-specific adorning of JVM mangled names is Jasmin-
specific, and such code has no place in symdef

64 bit registers are represented as a pair of 32 bit registers

whether the mangled name is for defining a symbol, or for referencing
it later (e.g. for a call or load of its address). The reason is that
on the JVM both cases are different.
+ jvmdef unit to encode types according to the JVM rules
+ tprocdef.jvmmangledname() to encode a procdef's JVM mangled name
(the common part of defining/referencing it; tprocdef.mangledname
afterwards adorns it as required)
git-svn-id: branches/jvmbackend@18288 -
* Do not initialize unused symbols, because finalization code is not generated for them either.
* Always initialize/finalize such constants, even if they are declared in {$J-} state and cannot be modified by user code.
git-svn-id: trunk@18121 -
+ parsing of section directive for variables
+ section test
+ write section names in the assembler/binary writers correctly
* allow section only after ; and for embedded targets
git-svn-id: branches/usersections@17154 -
* Unified fpc_initialize_array,fpc_finalize_array with fpc_decref_array and fpc_addref_array by removing 'size' parameter from the former two. Element size is easily calculated from RTTI, so omitting it simplifies code generation. All four helpers are now callable by tcg.g_array_rtti_helper().
* ncgutil.pas: initialization of open array out-parameters is now done properly (using fpc_initialize_array).
+ Test
