- Revision 1.2 2003-01-05 13:36:54 florian
|
|
|
- * x86-64 compiles
|
|
|
- + very basic support for float128 type (x86-64 only)
|
|
|
-
|
|
|
- Revision 1.1 2002/07/24 22:38:15 florian
|
|
|
- + initial release of x86-64 target code
|
|
|
-
|
|
|
- Revision 1.22 2002/07/01 18:46:34 peter
|
|
|
- * internal linker
|
|
|
- * reorganized aasm layer
|
|
|
-
|
|
|
- Revision 1.21 2002/05/18 13:34:25 peter
|
|
|
- * readded missing revisions
|
|
|
-
|
|
|
- Revision 1.20 2002/05/16 19:46:52 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 16:53:18 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 19:06:13 peter
|
|
|
- * removed unused units
|
|
|
- * use tlocation.size in cg.a_*loc*() routines
|
|
|
-
|
|
|
- Revision 1.15 2002/04/02 17:11:39 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
|
|
|
-
|
|
|
- Revision 1.14 2002/01/24 18:25:53 peter
|
|
|
- * implicit result variable generation for assembler routines
|
|
|
- * removed m_tp modeswitch, use m_tp7 or not(m_fpc) instead
