list information etc.

$Log$
Revision 1.16 2002-04-25 20:14:56 peter
* updated compilerprocs
* incr ref count has now a value argument instead of var
Revision 1.15 2002/04/24 16:15:35 peter
* fpc_finalize_array renamed
Revision 1.14 2002/04/21 18:56:59 peter
* fpc_freemem and fpc_getmem compilerproc
Revision 1.13 2002/01/21 20:16:08 peter
* updated for dynarr:=nil
Revision 1.12 2001/12/03 21:39:20 peter
* freemem(var) -> freemem(value)
Revision 1.11 2001/09/29 21:32:47 jonas
* almost all second pass typeconvnode helpers are now processor independent
* fixed converting boolean to int64/qword
* fixed register allocation bugs which could cause internalerror 10
* isnode and asnode are completely processor indepent now as well
* fpc_do_as now returns its class argument (necessary to be able to use it
properly with compilerproc)
Revision 1.10 2001/09/05 15:22:09 jonas
* made multiplying, dividing and mod'ing of int64 and qword processor
independent with compilerprocs (+ small optimizations by using shift/and
where possible)
Revision 1.9 2001/09/04 11:38:55 jonas
+ searchsystype() and searchsystype() functions in symtable
* changed ninl and nadd to use these functions
* i386 set comparison functions now return their results in al instead
of in the flags so that they can be sued as compilerprocs
- removed all processor specific code from n386add.pas that has to do
with set handling, it's now all done in nadd.pas
* fixed fpc_set_contains_sets in genset.inc
* fpc_set_in_byte is now coded inline in n386set.pas and doesn't use a
helper anymore
* some small fixes in compproc.inc/set.inc regarding the declaration of
internal helper types (fpc_small_set and fpc_normal_set)
Revision 1.8 2001/09/03 13:27:43 jonas
* compilerproc implementation of set addition/substraction/...
* changed the declaration of some set helpers somewhat to accomodate the
above change
* i386 still uses the old code for comparisons of sets, because its
helpers return the results in the flags
* dummy tc_normal_2_small_set type conversion because I need the original
resulttype of the set add nodes
NOTE: you have to start a cycle with 1.0.5!
Revision 1.7 2001/08/30 15:43:15 jonas
* converted adding/comparing of strings to compileproc. Note that due
to the way the shortstring helpers for i386 are written, they are
still handled by the old code (reason: fpc_shortstr_compare returns
results in the flags instead of in eax and fpc_shortstr_concat
has wierd parameter conventions). The compilerproc stuff should work
fine with the generic implementations though.
* removed some nested comments warnings
Revision 1.6 2001/08/29 19:49:04 jonas
* some fixes in compilerprocs for chararray to string conversions
* conversion from string to chararray is now also done via compilerprocs
Revision 1.5 2001/08/28 13:24:47 jonas
+ compilerproc implementation of most string-related type conversions
- removed all code from the compiler which has been replaced by
compilerproc implementations (using (ifdef hascompilerproc) is not
necessary in the compiler)
Revision 1.4 2001/08/23 14:28:36 jonas
+ tempcreate/ref/delete nodes (allows the use of temps in the
resulttype and first pass)
* made handling of read(ln)/write(ln) processor independent
* moved processor independent handling for str and reset/rewrite-typed
from firstpass to resulttype pass
* changed names of helpers in text.inc to be generic for use as
compilerprocs + added "iocheck" directive for most of them
* reading of ordinals is done by procedures instead of functions
because otherwise FPC_IOCHECK overwrote the result before it could
be stored elsewhere (range checking still works)
* compilerprocs can now be used in the system unit before they are
implemented
* added note to errore.msg that booleans can't be read using read/readln
Revision 1.3 2001/08/13 12:40:16 jonas
* renamed some str(x,y) and val(x,y) helpers so the naming scheme is the
same for all string types
+ added the str(x,y) and val(x,y,z) helpers for int64/qword to
compproc.inc
Revision 1.2 2001/08/06 14:13:55 jonas
* changed buf parameter of fpc_type_write from var to const
+ added names of helpers in typefile.inc to compproc.inc
Revision 1.1 2001/08/01 15:00:10 jonas
+ "compproc" helpers
* renamed several helpers so that their name is the same as their
"public alias", which should facilitate the conversion of processor
specific code in the code generator to processor independent code
* some small fixes to the val_ansistring and val_widestring helpers
(always immediately exit if the source string is longer than 255
chars)
* fixed fpc_dynarray_high and fpc_dynarray_length if the dynarray is
still nil (used to crash, now return resp -1 and 0)
