78e68b89df * gen_load_cgpara_loc() should only honour reusepara if it's a memory 
parameter

03a3136525 * since extended values are represented as "array[1..10] of byte" in records 
for llvm in order to ensure that it doesn't allocate the ABI-specified
    size, we have to convert the resulting pointer to an array of 10 bytes
    into a pointer to extended when we subscript the record (like is already
    done for arrays)

b9138a1c90 * changed the llvm type of comp/currency in parameter and return type 
on platforms that use the x87 for these types to extended in order
    to gaurantee the expected parameter passing conventions

b3e786eb77 - don't specify lef_inaggregate when getting the llvm type representation 
for function results and parameters (they're not in an aggregate, and this
    caused 80 bits extended floating point types to be translated into arrays
    of 10 bytes, which have different ABI meanings)

70ffaba901 * ensure that the loading of the uninitialised function result for llvm 
doesn't result in a temp allocation, since this can happen while
    generating the exit code

f7b5ee64ae * always insert type conversion for pasbool to int on llvm, as pasbool is 
represented by i1 while equally sized integers are i8

3496129f79 * only handle a_load_const_ref() directly when storing ordinals, as in case 
of pointers llvm only supports 0 (as null, which we don't generate either)

e2cf90ad8a * add type declarations for structure types in the llvm code so that we can 
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

c8e44e4a7c * keep track of whether we're in an inline assembly block in the llvm 
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)

4a25afb839 * load an undef value in the function result in the exit code of a pure 
assembler function, as the inline assembly code itself will be
    responsible for returning the function result (we will have to add
    the "return" instruction to it) while llvm requires a terminator
    at the end of the function and it must return something

f94f9f44e4 * convert all arguments to integers in case of comparisons of pointers with 
constants on llvm, as you can only compare with "null" in that case
  * convert all arguments to integers in case of pointer subtractions,
    as pointer subtractions are not supported by llvm

5a2609933f * fixed crash in r30244 (we only have to get a new elementdef if we didn't 
already initialise the location, and we won't get a new elementdef if

e924dbed90 * moved the specification of the options for a ttai_typedconstbuilder from 
get_final_asmlist() to the constructor, in preparation of supporting the
    creation of internal builders for local data that will ignore some of the
    irrelevant flags (at creation time)

9c42437326 * moved tasmlisttypedconstbuilder.tc_emit_string_offset() to

76e0ee7a41 * fixed adding padding bytes before anonymous records: the alignment of such 
records is only known once we have completely parsed all of their data
    (the alignment of a record depends on the alignment requirements of its
     field with the largest alignment) -> only insert the padding bytes after
    completely parsing them

d2b55b6f07 * moved the recording of aggregate type information during typed constant 
parsing from nllvmtcon to aasmcnst
   o added automatic insertion of padding bytes when fields need to be aligned,
     so that once ncgvmt (and hopefully ncgrtti) are converted to the typed
     constant builder class, we can get rid of all the explicit alignment
     directives (only supported for non-bitpacked records for now)
