|
|
- * bugfix of hdisponen (base must be set, not index)
|
|
|
- * more portability fixes
|
|
|
-
|
|
|
- Revision 1.53 2002/05/18 13:34:23 peter

- Revision 1.49 2002/05/12 16:53:17 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
|
|

|
|
|
- * removed newn and disposen nodes, the code is now directly
|
|
|
- inlined from pexpr
|
|
|
- * -an option that will write the secondpass nodes to the .s file, this
|
|
|
- requires EXTDEBUG define to actually write the info
|
|
|
- * fixed various internal errors and crashes due recent code changes
|

|
|
- * changeregsize -> rg.makeregsize
|

- Revision 1.45 2002/04/15 19:44:21 peter
|
|
|
- * fixed stackcheck that would be called recursively when a stack
|
|
|
- error was found
|
|
|
- * generic changeregsize(reg,size) for SPARC register resizing
|
|
|
- * removed some more routines from cga unit
|
|
|
- * fixed returnvalue handling
|
|
|
- * fixed default stacksize of linux and go32v2, 8kb was a bit small :-)

- Revision 1.44 2002/04/04 19:06:10 peter
|
|
|
- * removed unused units
|
|
|
- * use tlocation.size in cg.a_*loc*() routines
|
|
|

|
|
|
- Revision 1.43 2002/04/02 17:11:35 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 1.42 2002/03/31 20:26:38 jonas
|
|
|
- + a_loadfpu_* and a_loadmm_* methods in tcg
|
|
|
- * register allocation is now handled by a class and is mostly processor
|
|
|
- independent (+rgobj.pas and SPARC/rgcpu.pas)
|
|
|
- * temp allocation is now handled by a class (+tgobj.pas, -SPARC\tgcpu.pas)
|
|
|
- * some small improvements and fixes to the optimizer
|
|
|
- * some register allocation fixes
|
|
|
- * some fpuvaroffset fixes in the unary minus node
|
|
|
- * push/popusedregisters is now called rg.save/restoreusedregisters and
|
|
|
- (for SPARC) uses temps instead of push/pop's when using -Op3 (that code is
|
|
|
- also better optimizable)
|
|
|
- * fixed and optimized register saving/restoring for new/dispose nodes
|
|
|
- * LOC_FPU locations now also require their "register" field to be set to
|
|
|
- R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
|
|
|
- - list field removed of the tnode class because it's not used currently
|
|
|
- and can cause hard-to-find bugs
|
|
|
-
|
|
|
- Revision 1.41 2002/03/04 19:10:13 peter
|
|
|
- * removed compiler warnings
