of in X8, as the ABI allows this deviation (see added comments) and it's
required for some internal RTL code to call interface methods via RTTI

instead of the frame pointer register:
1) we exactly know the offsets of the temps from the stack pointer
after pass 1 (based on the require parameter stack size for called
routines), while we don't know it for the frame pointer (it depends
on the number of saved registers)
2) temp offsets from the stack pointer are positive while those from
the frame pointer are negative, and we can directly encode much
bigger positive offsets in the instructions
o move the stack pointer register to a virtual register in
loadparentfpn, because many instructions cannot directly operate
on/with the stack pointer
o add the necessary register interference edges for the stack pointer
register

convention code is triggered before the object structure has been
finalised, so the result can be different in the interface and
implementation. To solve this, something like r20161 has to be
implemented for TP-style objects

paramgr.pas, tparamanager:
+ add new method "handle_common_ret_in_param"
* extract common code (safecall + record constructor handling) from "ret_in_param" to "handle_common_ret_in_param" and call the latter in "ret_in_param"
[aarch64,arm,avr,i386,x86_64]/cpupara.pas, tCPUparamanager.ret_in_param:
* call "handle_common_ret_in_param" instead of implementing the same check again and again
ncgcal.pas, tcgcallnode.handle_return_value:
* move the check for (record) constructors to "tparamanager.handle_common_ret_in_param"
git-svn-id: trunk@23520 -
that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef
