5e1bb8e408 + tcalo_make_dead_strippable to indicate that a typed constant data block
should be dead-strippable; may imply the creation of a separate section
    (on platforms that dead-strip data based on sections), but does not
    require it
  * replaced all existing tcalo_new_section uses with
    tcalo_make_dead_strippable, as that is their meaning/purpose

e924dbed90 * moved the specification of the options for a ttai_typedconstbuilder from
get_final_asmlist() to the constructor, in preparation of supporting the
    creation of internal builders for local data that will ignore some of the
    irrelevant flags (at creation time)

82d92dbf50 * call seterrno instead of manually handling the setting setting the errno
threadvar (and having to deal with differences between the ELFv1 and ELFv2
    ABIs regarding indirect function calls, + future ability to have the
    compiler generate PIC for those routines)
   o includes workaround for lack of linkage area size allocation in current
     released PPC64 versions, remove after 3.0.2 has been released

53680329d3 * changed type of operatingsystem_parameter_argc from ptruint to longint,
as that's the type of argc in the system unit (which maps onto this
    variable), and even in C it's "int argc". This fixes the use of this
    variable on big endian targets

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
  * also handle arrays for the ELFv2 ABI when determining whether an aggregate
    only contains floating values of a single type

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

    values, as if those values were passed individually on ppc64/ELFv2

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)

1e227f78fe * factored out the check for whether we have to generate dotted function
names, and disabled them for ppc64 ELFv2

    function descriptor
