ttai_typedconstbuilder so that it can be overridden by other platforms
* override get_string_symofs() for LLVM and always return 0, as you can't
have labels in the middle of a declaration on that platform
git-svn-id: branches/hlcgllvm@28140 -
ttai_lowleveltypedconstbuilder
o set the offset to 0 in the llvm constbuilder before calling
the lowlevel one, because it incorporates this offset already
via getelementptr instructions
git-svn-id: branches/hlcgllvm@28136 -
same string constant to be merged together into a single tai_string
(required to efficiently represent string constants in llvm assembler
--i.e., without splitting them into bytes--, while keeping the
flexibility in the typed constant parser to mix individual elements
and strings)
git-svn-id: branches/hlcgllvm@28135 -
rather than first concatenating everything, because in case of
instructions that have other tai as operands we have to ensure that
all previous output is flushed before the tai-operand is evaluated
(and written/flushed)
git-svn-id: branches/hlcgllvm@28125 -
o now simple typed constants (integer, floating pointer, pchar)
and (non-variant) record typed constants containing such
elements work for llvm
git-svn-id: branches/hlcgllvm@28124 -
a procvardef
* handle procdefs like procvardefs when getting their string representation
in arbitrary expressions
git-svn-id: branches/hlcgllvm@28123 -
convert one def to another, including information regarding whether
it should be done via an intermediate integer typecast
* use this routine in hlcgllvm
git-svn-id: branches/hlcgllvm@28116 -
backend (required for inserting bitcasts/ptrtoint/... operations inside
typed constant declarations)
o taillvm constructors for creating bitcast-style and getlementptr
operations that accept a tai as their source/base operand
git-svn-id: branches/hlcgllvm@28112 -
typed constant data
o llvm declarations now get an extra "initdata" list that contains the
typed constant data associated with this declaration (if any)
git-svn-id: branches/hlcgllvm@28111 -
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 -
it can be directly indexed rather than that we need to separately
select the byte or data (just like at the Pascal level, and how it
is/will be handled in the code generator)
git-svn-id: branches/hlcgllvm@27015 -
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
git-svn-id: branches/hlcgllvm@27013 -
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 -
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 -
