already in a register, as this changes the result location into a size
different from what resultdef says (and only in that specific case)
o modified the ppc code so that it always forces a setelementn to uinttype,
as that is the size that is expected by the operations later on

GNU as from binutils for Darwin, and Apple's "as" is based on an old
version of GNU as)
o this will not cause any backward compatibility problems, as the
previous identifier for as_darwin was "AS-Darwin" and the compiler
compared the uppercase value of the -A parameter to the identifier,
so it was not explicitly selectable earlier. The new name is "AS",
so it is explicitly selectable via -Aas like on other platforms.

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
labels of LOC_JUMP in the node's location. This generates some extra jumps
for short circuit boolean and/or-expressions if optimizations are off, but
with optimisations enabled the generated code is the same (except for JVM
because the jump threading optimisation isn't enabled there yet).

something without a location at all; it's a hint/optional operation,
so if there's nothing to prefetch just don't do anything
(mantis #27811)
git-svn-id: trunk@30502 -
* 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

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
(mantis #27634)
git-svn-id: trunk@30164 -
* force the left operand into a register if both the left and
right are constants (can happen because not all set add-nodes
are handled in taddnode.simplify) because the code below
expects at least one register operand. Fixes the compilation of a.o.
taddset2 with -O3 on ppc (constant propagagation -> 2 constant
operands)
git-svn-id: trunk@27607 -
do_spill_replace routines, will be necessary by llvm register
allocator to determine the tdef corresponding to that register
* replaced uses of taicpu with tai_cpu_abstract_sym in the register
allocator so that it can work both with taicpu and taillvm instructions
git-svn-id: branches/hlcgllvm@26043 -
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
git-svn-id: trunk@23325 -
symbols on darwin/ppc and darwin/i386, and also for common symbols on
darwin/ppc, as they're not required for other kinds of symbols on those
platforms (gcc doesn't use them either with -O1 and higher; it does use
them always for darwin/ppc64 except for local symbols, and hence so do we)
git-svn-id: trunk@22271 -
getintparaloc + adapted all call sites of getintparaloc. This
led to a number of additional, related changes:
o corrected the type information for some getintparaloc parameters
o don't allocate some intparalocs in cases they aren't used
o changed "const tvardata" parameter into "constref tvardata" for
fpc_variant_copy_overwrite to make pass-by-reference semantics
explicit
o moved a number of routines that now have to call find_system_type()
from cgobj to hlcgobj so that cgobj doesn't have to start depending
on the symtable unit
o added versions of the cpureg alloc/dealloc methods to hlcgobj that
call through to their cgobj counter parts, so we can call save/restore
the cpu registers before/after calling system helpers from hlcgobj
(not implemented in hlcgobj itself, because all basic register
allocator functionality is still part of cgobj/cgcpu)
git-svn-id: trunk@21696 -
method is only used anymore internally in cgobj.tcg and its descendants
* made tcg.g_indirect_sym_load() protected to ensure it stays that way
