You can access C variables using 64x inline asm, but you have to be careful.
The C
vars should not be on the stack and you should test it first with all
optimizations
turned off. You have to add more lines, like:
asm(" .ref _val1");
asm(" .ref _val2");
asm(" swap2 _val1, _val2");
those are just examples, be careful. In "TMS320C6000 Optimizing Compiler
User's
Guide" document:

check out section 8.5.8, Using Inline Assembly Language.
