Revision 1.77 2003-08-20 20:13:08 daniel
|
|
* Fixed the fixed trouble
|
|
|
|
Revision 1.76 2003/08/20 20:11:24 daniel
|
|
* Fixed some R_NO trouble
|
|
|
|
Revision 1.75 2003/07/20 16:26:43 jonas
|
|
* fix for threadvars with -dnewra
|
|
|
|
Revision 1.74 2003/07/06 17:58:22 peter
|
|
* framepointer fixes for sparc
|
|
* parent framepointer code more generic
|
|
|
|
Revision 1.73 2003/07/06 15:25:54 jonas
|
|
* newra fix for threadvars
|
|
|
|
Revision 1.72 2003/06/15 15:13:12 jonas
|
|
* fixed register allocation for threadvar loads with newra
|
|
|
|
Revision 1.71 2003/06/13 21:19:30 peter
|
|
* current_procdef removed, use current_procinfo.procdef instead
|
|
|
|
Revision 1.70 2003/06/12 16:43:07 peter
|
|
* newra compiles for sparc
|
|
|
|
Revision 1.69 2003/06/09 16:41:52 jonas
|
|
* fixed regvar optimization for call_by_reference parameters (no need
|
|
to load address in another register)
|
|
|
|
Revision 1.68 2003/06/08 18:27:15 jonas
|
|
+ ability to change the location of a ttempref node with changelocation()
|
|
method. Useful to use instead of copying the contents from one temp to
|
|
another
|
|
+ some shortstring optimizations in tassignmentnode that avoid some
|
|
copying (required some shortstring optimizations to be moved from
|
|
resulttype to firstpass, because they work on callnodes and string
|
|
addnodes are only changed to callnodes in the firstpass)
|
|
* allow setting/changing the funcretnode of callnodes after the
|
|
resulttypepass has been done, funcretnode is now a property
|
|
(all of the above should have a quite big effect on callparatemp)
|
|
|
|
Revision 1.67 2003/06/07 18:57:04 jonas
|
|
+ added freeintparaloc
|
|
* ppc get/freeintparaloc now check whether the parameter regs are
|
|
properly allocated/deallocated (and get an extra list para)
|
|
* ppc a_call_* now internalerrors if pi_do_call is not yet set
|
|
* fixed lot of missing pi_do_call's
|
|

* procedures now calculate the parast addresses after the procedure
|
|
directives are parsed. This fixes the cdecl parast problem

|
|
to keep the library info stored for the module. In the future the
|
|
objectfiles will also be stored to the tasmlibrarydata class
