r969ee0df r9c90718 1 1 /* Translation rules for exception handling code, from Cforall to C. 2 2 * 3 * Note that these are not final. Names, syntax and the exact translation 4 * will be updated. The first section is the shared definitions, not generated 5 * by the local translations but used by the translated code. 3 * Reminder: This is not final. Besides names and things it is also going very 4 * much for correctness and simplisity over efficiency. 5 * 6 * The first section is the shared definitions, not generated by the local 7 * translations but used by the translated code. 6 8 * 7 9 * Most of these exist only after translation (in C code).
