1c01d52ea6 * Improvements of tprocinfo class:
* 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.

f13f6627c4 * moved use_fixed_stack from cgutils to a method in paramgr so it can
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

229cbca086 * propagate pi_has_assembler_block and pi_uses_exceptions flags from inlined
routines to their host, as in this case the stack frame cannot be omitted
    (mantis #16874)

7d459cf12a * the compiler now explicitly keeps track of the minimally guaranteed
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)

335bc9fd46 + PIC support for darwin/ppc32 (-Cg works now, no regressions in test
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)

     this is done, currently only activated for darwin-i386)
