Hi Paul and Akira, I have read through the first half of Chapter memorder, and here is correction for a few typos. Please take a look. For the first patch, the last clause I modified still looks confusion to me. Currently the clause is "though only if both \co{r1} and \co{r3} both end up containing the address of \co{x}"; however, my understanding is that prior load or store would also be ordered before the store on line 16, __only if r1 ends up containing the address of x__. That is, it is not necessary to involve r2/r3. Is my understanding correct? Or did I miss anything about this in the book?
