* $CPU/cgcpu.pas: disable the generation of VMT loading code
* dbgstabs.pas, dbgdwarf.pas: treat virtual methods of helpers as normal methods
* ncgcal.pas: don't register virtual helper methods for WPO
* ncgrtti.pas: write virtual helper methods as normal methods to RTTI
* nobj.pas: correctly handle final and override cases in helpers
* pdecvar.pas: property getters
* rautils.pas: no VMT offset in records

by reference, and dereference the (hidden) pointer in the DW_AT_location
block. This solves problems with function parameters defined as 'var'
git-svn-id: trunk@16683 -
as a class-structure directly. Make sure that in this case:
- The size is the size of the structure, not the size of a pointer
- The (hidden) pointer is dereferenced
- The class is marked as unallocated when the (hidden) pointer is nil
git-svn-id: trunk@16674 -
is_implicit_pointer_object_type() to better indicate the purpose of
that routine, and to avoid having to change its name every time
a new object type with this property is added
git-svn-id: trunk@16664 -
- extended write_symtable_procdefs to handle record definitions
- fix stabs info generator to use prefixed symbol names for record methods, also handle records static symbols the same way as for object types
- fix dwarf info record generation: add visibility info and write methods, also prefix record members the same way as object members
git-svn-id: branches/paul/extended_records@16570 -
- rename property_dec from pdecobj to struct_property_dec because pdecl also has property_dec and move it to interface to use by records + allow properties for records
- use struct_property_dec in record parser
- change structh type from objectdef to abstractrecorddef in read_property_dec to use by records
- disallow stored and default modifiers for records because records are not used for streaming
- fix misuse of search_sym_in_class for records in few places
git-svn-id: branches/paul/extended_records@16548 -
- rename tprocdef._class to tprocdef.struct and change the type from tobjectdef to tabstractrecorddef because methods can belong not to classes only now but to records too
- replace in many places use of current_objectdef to current_structdef with typcast where is needed
- add an argument to comp_expr, expr, factor, sub_expr to notify that we are searching type only symbol to solve the problem with records,objects,classes which contains fields with the same name as previosly declared type (like:
HWND = type Handle;
rec = record
hWnd: HWND;
end;)
- disable check in factor_read_id which was made for object that only static fields can be accessed as TObjectType.FieldName outside the object because it makes SizeOf(TObjectType.FieldName) imposible and since the same method was extended to handle records it also breaks a52 package compilation
- rename tcallcandidates.collect_overloads_in_class to tcallcandidates.collect_overloads_in_struct and addapt the code to handle overloads in records too
- fix searchsym_type to search also in object ancestors if we found an object symtable
- add pd_record, pd_notrecord flags to mark procedure modifies which can or can't be used with records. Disallow the next modifiers for records: abstract, dynamic, export, external, far, far16, final, forward, internconst, internproc, interrupt, message, near, override, public, reintroduce, virtual, weakexternal,
Allow the next modifiers for records: static

+ adds the missing DWARF3 values
+ introduces the DWARF4 values
+ basic class and debug info structures for DWARF4 support
+ added DWARF4 compiler parameter (-gw4) support
+ updated parameter description
git-svn-id: trunk@16288 -
+ support for nested procedural variables:
o activate using {$modeswitch nestedprocvars} (compatible with all
regular syntax modes, enabled by default for MacPas mode)
o activating this mode switch changes the way the frame pointer is
passed to nested routines into the same way that Delphi uses (always
passed via the stack, and if necessary removed from the stack by
the caller) -- Todo: possibly also allow using this parameter
passing convention without enabling nested procvars, maybe even
by default in Delphi mode, see mantis #9432
o both global and nested routines can be passed to/assigned to a
nested procvar (and called via them). Note that converting global
*procvars* to nested procvars is intentionally not supported, so
that this functionality can also be implemented via compile-time
generated trampolines if necessary (e.g. for LLVM or CIL backends
as long as they don't support the aforementioned parameter passing
convention)
o a nested procvar can both be declared using a Mac/ISO Pascal style
"inline" type declaration as a parameter type, or as a stand-alone
type (in the latter case, add "is nested" at the end in analogy to
"of object" for method pointers -- note that using variables of
such a type is dangerous, because if you call them once the enclosing
stack frame no longer exists on the stack, the results are
undefined; this is however allowed for Metaware Pascal compatibility)
git-svn-id: trunk@15694 -
reset_used_unit_defs()/reset_all_defs() calls:
o removed resetting tprocdef.procstarttai/procendtai and
instead check in the debug writers whether the def is
in the current unit or not to determine whether we should
write debug info for it
o use the collected defs in the wpoinfo structure to reset
the wpo flags in the defs, instead of iterating over all
defs in the program and resetting them that way
- removed now unused "is_reset" flag from tmodule
git-svn-id: trunk@15501 -
- sort of reverted r14134, which is no longer required after the above
change (new_section() inserts the alignment itself)
* made the tai_section.create() constructor private so it cannot be
called directly anymore
git-svn-id: trunk@15482 -
(it means that if the pointer is nil, the value is invalid; that's not the
case here, it just means that they are empty)
* generate upper bound of -1 (for dynarrays) or 0 (for ansi/unicodestrings)
if they are not allocated, so gdb can calculate their length as 0
(all based on tips by Jan Kratochvil)
git-svn-id: trunk@15288 -
search for an existing section with the same content first. This reduces the
generated executable size, compilation time and memory usage of the compiler
git-svn-id: trunk@15103 -
- add own symbol table for enumeration to store enumeration elements
- reimplement enumeration member traverse using symbol table instead of firstenum/nextenum - that members are removed
- implement TEnum.Element access syntax - element is searched in the enumeration symtable in this case instead of global/local symtables
- implement {$SCOPEDENUM ON/OFF} local switch
+ tests

properties/behaviour of the equivalent of Extended in C (i.e., to
"long double" on i386 and x86_64 platforms that support a 10 byte
long double, and to "double" elsewhere)
git-svn-id: trunk@14912 -
because the 'this' parameter was not used by gdb in that case for anything
anyway, and as of gdb 7.0 you get an error in gdb because the 'this'
parameter is not an aggregate in that case (but rather a pointer to the
vmt) (mantis #15362)
git-svn-id: trunk@14446 -
info with the classname, like is done for Stabs. Not done by default
because otherwise once calling methods from the debugger is implemented,
this would require typing classinstance.classname__methodname
git-svn-id: trunk@14337 -
a) use DW_TAG_variable instead of DW_TAG_constant in combination with a
DW_AT_constant_value, since that way gdb does support formal constants
b) store constant strings as either a shortstring or a longstring rather
than using DW_FORM_string, since gdb's Pascal printer doesn't support
gdb's generic STRING type yet for output
git-svn-id: trunk@14336 -
mark_NoLineinfoEnd
* add "no line info" markers for try/except and try/finally internal cleanup
code, so the debugger doesn't jump back and forth between the end and start
of exception blocks when you arrive at the end
* honour "no line info" markers in dbgdwarf.pas
git-svn-id: trunk@14327 -
procdefs after writing it, so that it can be written multiple times in
different units. It was only written once now, namely the first time it
was used. If this occurred before the implementation had been parsed, then
no info about low/high pc was written for this procdef.
* checking whether procstarttai is assigned is not a good way to determine
whether or not a procdef is defined in the current unit (it can also be
set if we are in the middle of parsing a uses clause, since all procdefs
are only reset afterwards). Check whether the parent static/globalsymtable
"iscurrentunit" instead.
git-svn-id: trunk@13912 -
o add accessibility info for fields and methods (public/protected/private)
o write method type info for methods not implemented in the current module
(for tf_dwarf_only_local_labels systems)
git-svn-id: trunk@13833 -
special treatment required to put self as the first parameter in the
debug info
+ added Apple-specific Objective-C related DWARF attributes
* properly emit debug information for Objective-C classes and methods
* fixed some typos in comments
* properly mark "absolute" local variables mapped to parameters as
variables in the debug info rather than as parameters (gdb expects one
parameter to be passed when calling functions from inside gdb per
parameter mentioned in the debug info, even if multiple parameters
have the same stack address)
