8fea7344c9 * added an extra parameter to ttai_typedconstbuilder.emit_pchar_const() to 
indicate whether it should create a copy of the pchar or not

452d9b747b * fixed code generation for initialized pointer variables, with the initial 
value set to the address of an external variable in the i8086 medium and
  compact memory models. Should fix Mantis #30107

1046c995a8 * ttai_typedconstbuilder.finalize_asmlist(): fixed handling of non-local 
symbols that aren't AB_GLOBAL (e.g. AB_PRIVATE_EXTERN)

926e62c886 + tai_aggregatetypedconst.changetorecord() to change the type of an 
aggregate to a (new) recorddef
   o the size of the original type and that of the record must match
   o will be used by the LLVM generator in case of a variant record, or
     an array of variant records with constant data that does not match
     our canonical LLVM definition

f83f9168ee * emit all resource strings and internal dynamic string data using the 
def representing that string type, instead of using p(wide)char
   o these string types are represented the same in llvm as p(wide)char,
     but this way we can check whether the emitted data type matches the
     expected one in the future

5774238887 * always keep track of the field about to be emitted in curfield, as we 
will need this for LLVM to determine whether the emitted data completely
    matches the definition (if not, we have to create a def for the actual
    data)
  - removed no longer used fieldoffsets property

(mantis #29091)

f60a33f5af * moved darwin/aix-specific code for resource string sections to 
ttai_lowleveltypedconstbuilder (will have to be handled differently
    for llvm)

Jonas Maebe
96b529072a * factored out generating the start and end of a vectorized dead strippable 
section to the high level typed const builder, and use this functionality
    for the resource strings (generating items: todo)
  * fixed dead stripping unused resource strings (all string data was put in the
    same section since r30342)

 2015-11-21 12:36:06 +00:00

Jonas Maebe
fa7ebba80d + new tcalo_no_dead_strip flag for the high level typed const builder to 
indicate symbols that should never be removed by the linker
   o TODO for llvm, needs support for the @llvm.used array (only used for
     the compiler ident, so it's not that important

5a2217f645 + support for emitting simple placeholder elements in the high level 
typed const builder, for use when e.g. emitting a table preceded by
    the number of elements in case that number is only known afterwards

7def77dcc9 * we only support resourcestrings in ttai_typedconstbuilder.queue_emit_const() 
right now, so give an internalerror if something else is passed
  * use the correct type when emitting a resourcestring like that (it will store
    the address of the resource string -> pointer to an ansistring)

git-svn-id: trunk@31646 -
 2015-09-12 23:33:17 +00:00

c946a85ae6 * give an internalerror if a typed const builder is finalised while there 
is still an unfinished aggregate

e93660c170 - removed ttai_lowleveltypedconstbuilder.queue_addrn(), as we are always 
implicitly taking the address of a complex expression in a typed constant
    (you cannot put the contents of another memory location in a typed
    constant)

git-svn-id: trunk@31252 -
 2015-07-30 16:58:07 +00:00

0e42559047 * support for queueing an access to a series of fieldvarsyms by name in the 
typed const builder

6f4fe415e9 * support specifying the alignment of the start of an anonymous record 
in the typed const builder (packrecords is not enough in case there are
    only fields smaller than the desired alignment)

git-svn-id: trunk@31250 -
 2015-07-30 16:58:01 +00:00
Jonas Maebe
6f5905684f + support for specifying the name of fields added to anonymous record

    builder

ddeab221c0 * when starting a queued expression, immediately emit any necessary padding 
bytes,becayse if we emit them at the end then we may interpret the first
    padding byte as the final component of the queued expression

git-svn-id: trunk@31246 -
 2015-07-30 16:57:49 +00:00
Jonas Maebe
7a8b5fd6c5 * several fixes for emitting aggregate typed constants with C/ABI packing: 
o don't emit explicit padding bytes (LLVM adds them)
   o don't mark them in LLVM as packed either

b5081d76c6 * since we insert the internal ansistring record types in the symtable of 
the current module, also search it only there so that it doesn't depend
    on the state of the symtablestack (hopefully fixes mantis #28109)

bd8079f896 * cache and reuse procvardefs internally created to get the address of a 
procdef (halves the amount of memory needed to compile the googlapi
    package using a build unit, as done by fpmake)

3be51e1455 * fixed endless recursion in tabstractrecorddef.contains_float_field() in 
case a record contains an internal typed constant of its own type
    (which happened becuase such a typed constant is also fieldvarsym, solved
     by checking for sp_static) (mantis #27880)
  * fixed several other similar cases in the compiler where we are only
    interested in instance fields, but processed all fieldvarsyms
