3d9713b9c8 * has_single_field() now looks recursively into fields that are aggregate 
types until it finds a non-aggregate type, and then returns "true" if
    that aggregate (record or array) contains one element
  * it now also returns the type of that element directly rather than a
    tfieldvarsym, since we only care about the type and in case of an array
    there is no field

9788b01d31 * rewrote most of the special case handling of parameter passing on ppc64, 
documenting the pecularities of the various calling conventions and
    marking what we do and don't support currently

165aaea8a4 * made a separate abi entry for powerpc_darwin, as it's not exactly the same 
as the AIX abi (especially on ppc64)
   o replaced (for now) all checks for the AIX abi with a check for either the
     AIX or Darwin abi
   o changed the ABI of Darwin/ppc, Darwin/ppc64 and Mac OS/ppc to
     abi_powerpc_darwin

f0ee1a9ee3 * pass records that (recursively) only contain floating point values of the

fb27dff638 * generate ".abiversion 2" directive when targeting ppc64/ELFv2 
* generate code to load the TOC register if it's required, and
    emit the the ".localentry" directive to indicate to the linker
    where the actual function body starts
  * support the ".localentry" directive in the ppc64 assembler reader
   o disable the fpc_qword_to_double() assembler implementation for
     ELFv2, because we can't manually insert the .localentry directive
     before the stack allocation code
  * perform indirect calls on ppc64 via R12 in ncgcal, as R12 needs to
    contain the function address on entry on ppc64/ELFv2 (and it's
    a volatile register, so there's no problem with always using
    it)

    function descriptor

fc21845686 * fixed the allocation of R12 on ppc32/ppc64 when used to hold the value of 
the stack pointer during the prolog. This was done previously in
    tcg.g_proc_entry(), but that routine is called after register allocation
    and hence has no influence. Also cleaned up the deallocation of that
    register by moving the previously ifdef'd code to thlcgppcgen

37c2d0e60d * use Object_getClass(obj) instead of obj._class to get the class of an 
Objective-C instance on AArch64, as the latter helper from the runtime
    is a plain function call rather than an expensive message dispatch,
    and moreover it also works for protocols (the "class" method is part
    of NSObject, and protocols do not support it since there is no single
    root class and hence they may represent an instance of a class that
    does not derive from NSObject)
   o also call it to get the "self" pointer when calling class methods for
     protocols on AArch64 (fixes tobjc22a and tobjc22b on Darwin/AArch64)
   o also call it to get the metaclass of a class on Darwin/AArch64 (fixes
     tobjc25)
  - removed special handling of getting the Objective-C (meta)class for
    non-type nodes on other Darwin platforms, as this is also correctly

657ac78304 * Improved handling of registers used in assembler blocks. Assembler nodes no longer have lists of used registers attached to them. Instead, each specified register creates an allocation/deallocation pair and an additional tai_regalloc.markused item directly in the asmlist. This way, register lists are no longer limited to integer registers, and parsing no longer depends on paramanager to know which registers are volatile. 
If assembler block has no modified register list, it is still handled in pass2, by allocating all volatile registers (not only the integer ones as before).

Jonas Maebe
41fba0c4f7 * switched to using the stack pointer as base register for the temp allocator 
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

 2015-02-23 22:54:03 +00:00
Jonas Maebe
5bb89cc2f0 * keep track of the reason why a loadparentfpnode has been created: to 
load a value from a nested context, or to pass a context to a nested
    routine. In case a target uses both the stack and frame pointer, this
    difference can matter.

edb3124ae8 * copy arrays passed by value to cdecl routines on the callee side even on 
platforms that normally must copy value parameters on the caller side,
    because
   o if we copy them on the caller side, then the behaviour will be different
     compared to other platforms if the called routine is implemented in C
     (since they are passed by reference, changes to the array contents will
      be visible on other platforms, while they wouldn't be visible if the
      copy is made on the caller side)
   o if we don't copy them on the caller nor on the callee side, then behaviour
     will be different compared to other platforms if the called routine is
     implemented in Pascal and modifies the array (since then changes won't be
     visible on the caller side, except on platforms that normally perform
     the copy on the caller side)

c6ba0bb6fb + support for targets that require by-reference value parameters to be 
be copied on the caller instead of callee side
   o mark Darwin/Aarch64 as such a target (any AArch64 target will be like
     that normally, as its ABI specifies this behaviour)
   o don't mark by-reference value parameters on such targets as
     vo_has_local_copy, since a) they don't have one (the copy is on the
     caller side), and b) this ensures that all code handling such
     parameters automatically knows that they are still by reference
     after the init code has run
   o when making the copies on the caller side, don't increase the
     reference count for managed types except for variants, just like
     is done when making the copies on the callee side. This is because
     the reference count increasing code on the callee side only runs
     for non-assembler functions, and we cannot know 100% certain on the
     caller side whether the called function is assembler or not (e.g. in
     case of externally declared functions)
   o maybe over time we can reuse the Pascal code in
     tcallparanode.copy_value_by_ref_para to replace the equivalent code
     in hlcgobj and ncgutil also on the caller side for other targets
