* Added the tprocdef.parentfpsym property. Set parentfpsym.varstate to vs_read instead of using the pio_needs_parentfp flag.
* Replaced tcgcallparanode.push_zero_sized_value_para by tparamanager.has_strict_proc_signature.

- 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;

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

o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now

labels of LOC_JUMP in the node's location. This generates some extra jumps
for short circuit boolean and/or-expressions if optimizations are off, but
with optimisations enabled the generated code is the same (except for JVM
because the jump threading optimisation isn't enabled there yet).

+ implement trashing of local variables if subroutine is inlined
* fix some errors releated to interproc. gotos and inlining
+ node_count function
* inline cannot be used with iochecking and safecall calling conventions
* track inherited usage
* don't inline if inherited is used

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

always points to the previous r7 on the stack (with the saved return
address coming right after it) so that the debugger and crashreporter
can use it for backtraces as specified in the ABI
o changed NR_FRAME_POINTER_REG and RS_FRAME_POINTER_REG from a symbolic
into a typed constant, and added a new method to tprocinfo that can
be used to initialze it (so it can be inited to r7/r11 depending on
the target platform)
* allow using r9 on Darwin, it was only used by the system on iOS up to
2.x, which we no longer support
* prefer using r9 and r12 before r4..r11 on Darwin, because they are
volatile and hence do not have to be saved
git-svn-id: trunk@20661 -
* For now placed actual processing of unwind info under {$ifdef TEST_WIN64_UNWIND}, because in the current state it doesn't add much value.
git-svn-id: trunk@19200 -
o handle them like for regular classes (return a class instance,
although this is technically not true since they don't return
anything; will be changed in the future)
o because of the previous point, make sure that we handle the
"function result" properly and don't pop too many values from
the evaluation stack when calling one constructor from another
o added "extra_pre_call_code" method used by njvmcal to insert
the "new" opcode to create the new class instance before
calling a constructor
o when a constructor does not call any other constructor (inherited
or otherwise), automatically insert a call to the inherited
parameterless constructor as required by the jvm standard)
TODO: check that *if* an inherited or other constructor is called
from another constructor, that it does so as the first statement/
call

* Moved nestedprocs from tcgprocinfo to tprocinfo, in order to be able to access the entire nested procedure hierarchy without depending on psub.pas or code generator.
* Creating an instance of tprocinfo automatically inserts it into list of parent's nested procedures.
* nestedprocs list is created on demand. Public read-only access is provided by has_nestedprocs and get_first_nestedproc functions.
+ Method destroy_tree is provided for destroying the entire hierarchy of procinfo's. It can be called on any procinfo object in the tree.
+ Also added methods save_jump_labels and restore_jump_labels for asmlabel maintenance, which is currently being repeatedly done all over the codegenerator.

be used outside the code generator
* renamed tabstractprocdef.requiredargarea into callerargareasize,
and also added calleeargareasize field; added init_paraloc_info(side)
method to init the parameter locations and init those size fields and
replaced all "if not procdef.has_paraloc_info then ..." blocks with
procdef.init_paraloc_info(callersize)"
* moved detection of stack tainting parameters from psub to
symdef/tabstractprocdef
+ added tcallparanode.contains_stack_tainting_call(), which detects
whether a parameter contains a call that makes use of stack paramters
* record for each parameter whether or not any following parameter
contains a call with stack parameters; if not, in case the current
parameter itself is a stack parameter immediately place it in its
final location also for use_fixed_stack platforms rather than
first putting it in a temporary location (part of mantis #17442)
* on use_fixed_stack platforms, always first evaluate parameters
containing a stack tainting call, since those force any preceding
stack parameters of the current call to be stored in a temp location
and copied to the final location afterwards

alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)

suite compiled with -Cg compared to without -Cg)
+ support for using a virtual register as PIC/got base register
* moved got loading code from ncgutil to cgobj/cgcpu (can't test whether
it didn't break anything under linux/i386, because "make cycle OPT=-Cg"
was already broken due to the *prt*.as -> si_*.pp changes)
