to free up space for more ait_* types in taitype (can't have
more than 32 because they have to fit in a small set)
o factored out writing of floating point numbers as an array of
byte in the external assemblers
git-svn-id: branches/hlcgllvm@28105 -
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 -
o handle parameters and function results divided over multiple paralocs,
including generating fake recorddefs that represent
o fixed zero/sign extension handling
o properly handle difference between procdefs as printed for the
implementation, an alias declaration or a procvar definition
git-svn-id: branches/hlcgllvm@27009 -
o no support yet for many ait_* types, although eventually most of them
shouldn't be generated at all for the llvm target
o no support yet for calling "opt" (which optimises llvm bitcode) before
calling llc (which translates llvm bitcode into native code) -- compile
with -s and manually call "opt" with -std-compile-opts, -O1, -O2 or -O3
if you want to experiment
o override the assembler writer with the llvm one when compiling an llvm-
targeting compiler
o override the assembler file extension with .ll when compiling an llvm-
targeting compiler
