because due to aliasing symbols a single symbol may be called using
different procdefs (e.g. FPC_ANSISTR_UNIQUE in the system unit is defined
as an alias for a function and called as a procedure). This means we have
to insert extra type conversions for llvm, which requires both the source
and destination type
git-svn-id: trunk@30776 -
handle recursive record references (rec= record prec: ^rec)
o llvm unfortunately does not support recursive references to array types
or function pointers, so those will currently still result in endless
recursion when the compiler tries to write them out. Solving those
will require a lot of typecasting in the generated code
git-svn-id: trunk@30675 -
assembler writer, and for now skip writing labels if we are (they
will have to emitted as part of an actual inline assembly block,
not as llvm-style labels)
git-svn-id: trunk@30672 -
procdef.getcopyas(procvardef,pc_address_only) as the def if we want to
specify that we're interested in the address of a procedure/procvar of
object
git-svn-id: branches/hlcgllvm@28476 -
llvm
* instead, add LLVM-specific name mangling based on the asmsymbol's bind
and typ whenever we write out its name
git-svn-id: branches/hlcgllvm@28166 -
o remove the accompanying tdef operands from tai operands, because such
tai operands should have a tdef already
o check that every queued tai is a tai_simpletypedconst (which have a
type)
o wrap queued bitcast/getelementptr tai instances with a
tai_simpletypedconst
git-svn-id: branches/hlcgllvm@28154 -
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 -
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 -
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 -
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
