Revision 1.22 2002-07-01 18:46:29 peter
|
|
* internal linker
|
|
* reorganized aasm layer
|
|
|
|
Revision 1.21 2002/05/18 13:34:21 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.20 2002/05/16 19:46:50 carl
|
|
+ defines.inc -> fpcdefs.inc to avoid conflicts if compiling by hand
|
|
+ try to fix temp allocation (still in ifdef)
|
|
+ generic constructor calls
|
|
+ start of tassembler / tmodulebase class cleanup
|
|
|
|
Revision 1.18 2002/05/12 16:53:16 peter
|
|
* moved entry and exitcode to ncgutil and cgobj
|
|
* foreach gets extra argument for passing local data to the
|
|
iterator function
|
|
* -CR checks also class typecasts at runtime by changing them
|
|
into as
|
|
* fixed compiler to cycle with the -CR option
|
|
* fixed stabs with elf writer, finally the global variables can
|
|
be watched
|
|
* removed a lot of routines from cga unit and replaced them by
|
|
calls to cgobj
|
|
* u32bit-s32bit updates for and,or,xor nodes. When one element is
|
|
u32bit then the other is typecasted also to u32bit without giving
|
|
a rangecheck warning/error.
|
|
* fixed pascal calling method with reversing also the high tree in
|
|
the parast, detected by tcalcst3 test
|
|
|
|
Revision 1.17 2002/04/15 19:12:09 carl
|
|
+ target_info.size_of_pointer -> pointer_size
|
|
+ some cleanup of unused types/variables
|
|
* move several constants from cpubase to their specific units
|
|
(where they are used)
|
|
+ att_Reg2str -> gas_reg2str
|
|
+ int_reg2str -> std_reg2str
|
|
|
|
Revision 1.16 2002/04/04 19:06:07 peter
|
|
* removed unused units
|
|
* use tlocation.size in cg.a_*loc*() routines
|
|
|
|
Revision 1.15 2002/04/02 17:11:33 peter
|
|
* tlocation,treference update
|
|
* LOC_CONSTANT added for better constant handling
|
|
* secondadd splitted in multiple routines
|
|
* location_force_reg added for loading a location to a register
|
|
of a specified size
|
|
* secondassignment parses now first the right and then the left node
|
|
(this is compatible with Kylix). This saves a lot of push/pop especially
|
|
with string operations
|
|
* adapted some routines to use the new cg methods
|
|
|
