Revision 1.12 2003-12-01 18:43:32 peter
|
|
* s128real type is not compatible with s80real
|
|
|
|
Revision 1.11 2003/11/28 13:09:07 mazen
|
|
+ defintion of ts128real
|
|
+ globtype is needed in interface uses clause

Revision 1.10 2003/11/07 15:58:33 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
