- Do not remove the $parentfp parameter as was done in the previous optimization approach. Instead when $parentfp is unused to the following:
- On the caller side: Omit passing the value for $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=false (classic CPU targets).
Pass 0/nil as $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=true;
- On the callee side: Prevent allocation of registers/resources for $parentfp.
- When possible keep $parentfp in a register.
- Set the pio_nested_access flag in tprocinfo.set_needs_parentfp() to properly handle deep nesting levels;

- targets which use a special struct to access parent's variables;
- pure assembler procedures (for compatibility with old code).

Note: due to the way we access variables in a nested function (which in this case includes exception filters) we can not extract the finally handlers and call them (like we do on i386 and x86_64, but instead we duplicate the finally code)

implementation the compiler determined the routine must never be
inlined
o difference with po_noinline: can also be set in the implementation
o difference with pio_inline_not_possible: it indicates that e.g.
LLVM must not inline the routine either

the frame of the caller rather than of the current routine, which could
cause e.g. stackframes to be missed in RTL helpers that are known to be
only called from run time error routines)

Implemented attributes for class types and properties (based on work by Joost van der Sluis). Added TCustomAttribute - a base class for attributes. Added TUnitInfo record to RTTI. It contains the unit name and unit options (for now only a flag which specifies if the unit contains attributes). Added several tests for attributes.
git-svn-id: trunk@42356 -
the generation of the procdef's asmsymbols
o also removed unnecessary definition of procdef alias symbols for Darwin
(they are already defined in ncgutil.alloc_proc_symbol)
git-svn-id: trunk@42341 -
private_extern (or plain global in case of PECOFF, as the effect is
the same there): visible across object files, but they become local
when linked into a binary/library. This enables cross-unit inlining
of functions accessig implementation-only symbols.
git-svn-id: trunk@42340 -
Allows compilation of compiler using -dDEBUG_NODE_XML
which will generate a NAME-node-dump.xml file for each
unit, program or library compiled,
containing a XML description of the nodes handled during
compilation of the unit, program or library.

* nested exception handling statments in one procedure need to be fixed
* clean up, finally factor out tcgprocinfo from psub at least
* extensive testing
git-svn-id: branches/debug_eh@41289 -
o unsetting po_inline while parsing the implementation for various reasons
(interprocedural goto/label, accessing a local in a parent frame,
having nested procedures)
o instead handle this via the pio_inline_not_possible flag
o noreturn can no longer be specified only in the implementation
git-svn-id: trunk@40789 -
on pdecsub (node units should not depend on parser units):
o maybe_add_public_default_java_constructor()
o handle_calling_convention()
o create_finalizer_procdef() (replaced with create_outline_procdef())
o insert_record_hidden_paras()
o handle_calling_convention()
o proc_add_definition()
o build_parentfpstruct()
o maybe_guarantee_record_typesym()
o get_first_proc_str()
* factored out the creation of a procinfo for a nested procdef based on a
subnodetree of the current procdef into tprocinfo.create_for_outlining()
git-svn-id: trunk@40773 -
o use this flag to set the personality routine of a function if it uses
exception handlinga
o also define FPC_USE_PSABIEH if this target flag is set
o set this target flag for darwin/x86-64 if the compiler is compiled with
-dllvm
git-svn-id: branches/debug_eh@40415 -
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
o prevents dependency cycles that can cause llvm codegen units to init
before the cpu variants, which is bad since the llvm versions have to
override the cpu variants in their init code (+ added checks in the
init code that they are in fact initialised later)
git-svn-id: branches/debug_eh@40410 -
get initialised, so that parameters in this struct are already available
in any wrappers generated for the parent routine (e.g. in case self is
moved to the parentfpstruct in a destructor, which calls beforestruction
in its wrapper)
git-svn-id: trunk@40384 -
(needed for LLVM, where we need two copies of the finally code: one in case
an exception occurs, and one in case none is raised)
o also first finalize parameters and only then code generator temps, since
in theory the former could create more of the latter
git-svn-id: trunk@40345 -
Fix passing of vararg register pairs.
Fix passing of big record, and return of records.
Disabled framepointer elimination for the time being.
git-svn-id: branches/laksen/riscv_new@39519 -
a) correctly determine whether token recording is required or not (nested routines of generic routines don't need it)
b) correctly determine whether the trailing ";" needs to be parsed (nested routines of generic routines need to)
git-svn-id: trunk@36469 -
* don't parse a semicolon at the end for real specializations or specializations of methods that belong to a specialized class/record

This unit was empty unless OLDREGVARS macro was set,
but this does not compile and no change has been made since 2011.
* Remove regvars from all _USES clauses.
git-svn-id: trunk@34808 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary
git-svn-id: trunk@34164 -
* always register implementation-only, public routines as they might only be called from other units using an external declaration
