that deal with paths/filenames with TPathStr (= ansistring) to prevent
cutting off long paths (no change in speed when compiling the compiler,
1% extra memory usage)
git-svn-id: trunk@21120 -
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/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,

+ adds the missing DWARF3 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)

(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)

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

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

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)

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)
git-svn-id: branches/objc@13723 -
Darwin anymore), because otherwise if unit A is compiled without debug
info and unit B uses one of its types, the debug info will contain no
DW_TAG_typedef for that type and hence gdb will not recognise it as
a type definition that's part of the program.
git-svn-id: trunk@13424 -
starting with a previous 2.3.1 or compiler built from the objc branch
+ added basic objcprotocol support (only for external protocols
currently)
o use in type declaration: "type xp = objcprotocol ... end;"
o when defining a root class that implements it:
"type yc = objcclass(xp) ... end" (note: no support yet
for something like "objcclass(id,xp)" or so)
o when defining a non-root class that implements a protocol:
"type zc = objcclass(nsobject,xp) ... end"
o includes support for "required" and "optional" sections
o no support yet for the objcprotocol(<protocol>) expression
that enables getting a class instance representing the
protocol (e.g., for use with "conformsToProtocol:")
o message names have to specified in protocol declarations,
but if an objcclass implements a protocol, the message names do
not have to be repeated (but if they are, they have to match;
the same goes when overriding inherited methods)
+ allow specifying the external name of Objective-C classes and
protocols, since classes and protocols can have the same name
(and you cannot use the same Pascal identifier in such caseq)
+ added NSObject protocol, and make the NSObject class use it
+ added missing NSObject class methods that have the same name
as instance methods (added "class" name prefix to avoid clashes)
* fixed several cases where the compiler did not treat Objective-C
classes/protocols the same as Object Pascal classes/interfaces
(a.o., forward declarations, alignment, regvars, several type
conversions, ...)
* allow "override" directive in objcclass declarations, and print
a hint if it's forgotten in an external declaration (because it
doesn't really matter there, and may make automated header
conversion harder than necessary) and an error if will be used in
a non-external declaration (because it is not possible to start
a new vmt entry-tree in Objective-C, you can only override parent
methods)
* reject objcclasses/protocols as parameters to typeof()
* don't try to test VMT validity of objcclasses/protocols
git-svn-id: branches/objc@13375 -
TDebugInfoDwarf, so DWARFv2 and DWARFv3 generators can share protected
methods.
* fixed the debug info for sets whose language-level lower bound is not
equal to the actual set base used when storing the data (e.g., a "set
of 1..5" is actually stored as a "set of 0..7" or "set of 0..31")
(mantis #13984)
+ interactive test for the above
git-svn-id: trunk@13302 -
* Use DW_AT_byte_stride when possible, because gdb does not support DW_AT_stride_size
* Add stride to dynamic-array definitions
git-svn-id: trunk@13280 -
o support for declaring external Objective-C classes (see
rtl/inc/objcbase.pas), including derived classes
o support for converting methods of objcclasses into selectors
(see tests/test/tobjc1.pp)
o support for loading from/storing to fields of objcclasses
o support for calling Objective-C methods using regular
Object Pascal syntax (see tests/test/tobjc1.pp)
o some things that are known to be not yet working:
o automatic conversion from ID to objcclasses and back
o declaring and implementing new objcclasses/methods in Pascal code
o debug information (objcclasses are currently plain pointers
as far as the debugger knows)
