| 22 ; RATIONAL | |
| 23 ; | |
| 24 ; We must enforce good data passing between the C and the ASM parts of code. | |
| 25 ; The previous design used two independant definitions of each variable, | |
| 26 ; one in C, one in ASM. If they did not match, no error was generated, and | |
| 27 ; anything can happend at runtime... | |
| 28 ; | |
| 29 ; The new design use LINKING to ensure the variables defined in C are at the | |
| 30 ; same address when used in ASM code. And it uses a unique declaration file | |
| 31 ; (with suitable macros) to make sure they have the same size in both language. | |
| 32 ; | |
| 33 ; HISTORY | |
| 34 ; 2011-01-20: [jDG] Creation. | |
| 35 ; | |
| 36 ; NOTE | |
| 37 ; | |
| 38 ; This file have to obey both ASM and C syntax. The only common directives | |
| 39 ; are #if/#ifdef/#endif and the #define, so they are eavily used to do the | |
| 40 ; trick. | |
