Revision 1.5 2003-12-01 18:43:32 peter
|
|
* s128real type is not compatible with s80real
|
|
|
|
Revision 1.4 2003/11/17 23:23:47 florian
|
|
+ first part of arm assembler reader
|
|
|
|
Revision 1.3 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 1.2 2003/08/25 23:20:38 florian
|
|
+ started to implement FPU support for the ARM
|
|
* fixed a lot of other things
|
|
|
|
Revision 1.1 2003/07/21 16:35:30 florian
|
|
* very basic stuff for the arm
|
