Revision 1.8 2003-06-03 21:11:09 peter
|
|
* cg.a_load_* get a from and to size specifier
|
|
* makeregsize only accepts newregister
|
|
* i386 uses generic tcgnotnode,tcgunaryminus
|
|
|
|
Revision 1.7 2003/05/30 23:49:18 jonas
|
|
* a_load_loc_reg now has an extra size parameter for the destination
|
|
register (properly fixes what I worked around in revision 1.106 of
|
|
ncgutil.pas)
|
|
|
|
Revision 1.6 2003/01/05 13:36:53 florian
|
|
* x86-64 compiles
|
|
+ very basic support for float128 type (x86-64 only)
|
|
|
|
Revision 1.5 2002/09/07 15:25:00 peter
|
|
* old logs removed and tabs fixed
|
|
|
|
Revision 1.4 2002/08/19 18:17:48 carl
|
|
+ optimize64_op_const_reg implemented (optimizes 64-bit constant opcodes)
|
|
* more fixes to m68k for 64-bit operations
|
|
|
|
Revision 1.3 2002/08/17 22:09:43 florian
|
|
* result type handling in tcgcal.pass_2 overhauled
|
|
* better tnode.dowrite
|
|
* some ppc stuff fixed
|
|
|
|
Revision 1.2 2002/07/01 16:23:52 peter
|
|
* cg64 patch
|
|
* basics for currency
|
|
* asnode updates for class and interface (not finished)
|
|
|
|
Revision 1.1 2002/06/08 19:36:54 florian
|
