o make use of the fact that callparanodes always first load everything
in temporary parameters (allocated via paramanager.createtempparaloc)
-> we pass those temporary paralocs to the llvm call nodes and ignore
the "real" locations with physical registers
o all function results are forced to memory before handing them back
to the generic code generator to avoid having to deal with special
result locations and llvm<->pascal type differences (llvm removes
the extra temp stores/loads while optimising)
o ideally, the llvm code generator should share the common code with
the generic code generator for a_load_ref_cgpara() at some point in
the future

generate declarations when external symbols are referred in a taillvm
instruction
* added "declared" field to tasmsymbol for llvm to make avoid declaring a
symbol multiple times (harmless, but unnecessary)
* all kinds of declarations/definitions are now handled using the new
taillvmdecl, the old separate types have been removed
git-svn-id: branches/hlcgllvm@27010 -
destination types are different: the pointer types of the load/store must
be converted in that case, rather than the loaded/to be stored value
(you can't bitcast aggregates in LLVM)
git-svn-id: branches/hlcgllvm@26987 -
fpu: treat them as extended when they are loaded into registers, and as
int64 when loading from/storing to memory
