nestedprocpointertype; this was done initially before the JVM target knew
about the voidpointertype, but is no longer necessary (also fixes
mantis #26251)
git-svn-id: trunk@27838 -
o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls

+ added charfarpointertype and charnearpointertype to symdef
* the system unit compiles in the i8086 compact memory model now

as the hidden parentfp parameter, passed to nested procs. On i8086 it is
always a near pointer, unlike voidpointer (which changes according to the
memory model). This fixes nested procs in i8086 far data memory models.
git-svn-id: trunk@26934 -
now that there is no special assigned handling anymore, because the
generic "<>nil" code for method pointers loads the "proc" field
via an internally generated tmethod() typecast (using the
methodpointer type). Additionally, not loading this type was
an artefact from the time that it wasn't available yet for the
JVM target
git-svn-id: trunk@25558 -
a win64 compiler support the x87 types extended and comp/currency handled by the FPU, this
requires to use a i386 compiler as starting compiler and cross compilation because the starting
compiler must support the 80 bit extended type
git-svn-id: trunk@23023 -
defines INTERNAL_BACKTRACE (which assumes get_frame to be internal rather
than a system unit procedure)
* changed fpc_assert() declaration for jvm to be the same as for other
targets, so the same code can be used to call it in ninl now that's
called from the first pass
git-svn-id: trunk@21903 -
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

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()

- add helper function getansistringcodepage which returns explicitly set codepage or 0 in other case
- add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
- change tstoreddef.createnai constructor to allow set codepage in constructor
- don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
- don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)
+ test which covers most of the cases

only JVM constructs that are already implemented, but also ones that
will be supported in the future but that aren't implemented yet (to

default integer types)
* define CPUDEFINED in pp.pas if JVM is defined
* initialise the fpu types and currency in psystem for the JVM target
* set uinttype/sinttype to 32 bit types also for all cpu32bitaddr cpus
by default (required for JVM, which has a 64 bit alu but 32 bit
"addresses" -- an address takes up 1 stack slot, a 64 bit int two;
also, array indices are limited to 32 bit)
git-svn-id: branches/jvmbackend@18296 -
- move objname, objrealname fields from tobjectdef to tabstractrecorddef,
- load and save them from/to ppu file,
- use tabstarctrecorddef in some more places where previously code worked for tobjectdef
- change push_nested_hierarchy, pop_nested_hierarchy to handle records too
