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

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

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

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

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
git-svn-id: trunk@30202 -
same type (even in other records or in arrays), with 8 or less such
values, as if those values were passed individually on ppc64/ELFv2
git-svn-id: trunk@30200 -
* 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)
git-svn-id: trunk@30198 -
names, and disabled them for ppc64 ELFv2
* disabling those also disables the function descriptors, so use the
_CALL_ELF compiler variable to check whether there is in fact a
function descriptor
git-svn-id: trunk@30196 -
* specify the correct linker emulation to use for ppc64 ELFv2 little endian
* specify the correct default library directories to search for ELFv2 little
endian

Update ARM internal assembler to support most ARM, Thumb and Thumb-2 instructions.
Changed generation of VFP instructions to use UAL mnemonics.
Added divided and unified assembler syntax support to ARM assembly reader.
