- inc/dec didn't take care of CREGISTER
|
|
- register calculcation of inc/dec was wrong
|
|
- var/const parameters get now assigned 32 bit register, but
|
|
const parameters only if they are passed by reference !

|
(accepted are popstack cdecl and pascal)
|
|
+ added C vars with the following syntax
|
|
var C calias 'true_c_name';(can be followed by external)
|
|
reason is that you must add the Cprefix
|
|
|
|
which is target dependent
|
|
|
|
Revision 1.2 1998/06/08 13:13:29 pierre
