$Log$
Revision 1.22 2003-12-25 12:01:35 florian
+ possible sse2 unit usage for double calculations
* some sse2 assembler issues fixed
Revision 1.21 2003/12/25 01:07:09 florian
+ $fputype directive support
+ single data type operations with sse unit
* fixed more x86-64 stuff
Revision 1.20 2003/12/01 18:43:31 peter
* s128real type is not compatible with s80real
Revision 1.19 2003/11/12 16:05:39 florian
* assembler readers OOPed
+ typed currency constants
+ typed 128 bit float constants if the CPU supports it
Revision 1.18 2003/11/07 15:58:32 florian
* Florian's culmutative nr. 1; contains:
- invalid calling conventions for a certain cpu are rejected
- arm softfloat calling conventions
- -Sp for cpu dependend code generation
- several arm fixes
- remaining code for value open array paras on heap
Revision 1.17 2003/09/03 11:18:37 florian
* fixed arm concatcopy
+ arm support in the common compiler sources added
* moved some generic cg code around
+ tfputype added
* ...
Revision 1.16 2002/12/05 14:18:09 florian
* two comments fixed
Revision 1.15 2002/09/07 20:48:43 carl
* cardinal -> longword
Revision 1.14 2002/09/07 15:25:10 peter
* old logs removed and tabs fixed
Revision 1.13 2002/08/15 15:15:55 carl
* jmpbuf size allocation for exceptions is now cpu specific (as it should)
* more generic nodes for maths
* several fixes for better m68k support
Revision 1.12 2002/08/12 15:08:41 carl
+ stab register indexes for powerpc (moved from gdb to cpubase)
+ tprocessor enumeration moved to cpuinfo
+ linker in target_info is now a class
* many many updates for m68k (will soon start to compile)
- removed some ifdef or correct them for correct cpu
Revision 1.11 2002/08/10 14:47:50 carl
+ moved target_cpu_string to cpuinfo
* renamed asmmode enum.
* assembler reader has now less ifdef's
* move from nppcmem.pas -> ncgmem.pas vec. node.
Revision 1.10 2002/05/18 13:34:22 peter
* readded missing revisions
Revision 1.9 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 1.7 2002/04/20 21:37:07 carl
+ generic FPC_CHECKPOINTER
+ first parameter offset in stack now portable
* rename some constants
+ move some cpu stuff to other units
- remove unused constents
* fix stacksize for some targets
* fix generic size problems which depend now on EXTEND_SIZE constant
* removing frame pointer in routines is only available for : i386,m68k and vis targets
Revision 1.6 2002/04/07 13:41:50 carl
- moved type constant
Revision 1.5 2002/04/02 17:11:34 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
