heinrichsweikamp
parents:

24 ; We must enforce good data passing between the C and the ASM parts of code.
heinrichsweikamp
parents:
diff changeset
25 ; The previous design used two independant definitions of each variable,
heinrichsweikamp
parents:
diff changeset
26 ; one in C, one in ASM. If they did not match, no error was generated, and
heinrichsweikamp
parents:
diff changeset
27 ; anything can happend at runtime...
heinrichsweikamp
parents:
diff changeset
28 ;
heinrichsweikamp
parents:
diff changeset
29 ; The new design use LINKING to ensure the variables defined in C are at the
heinrichsweikamp
parents:
diff changeset
30 ; same address when used in ASM code. And it uses a unique declaration file
heinrichsweikamp
parents:
diff changeset
31 ; (with suitable macros) to make sure they have the same size in both language.
