| 13 | // What's wrong with compiler generated code? Because of the nature of | ||
| 14 | // C language, compiler doesn't [dare to] reorder load and stores. But | ||
| 15 | // being memory-bound, RC4 should benefit from reorder [on in-order- | ||
| 16 | // execution core such as IA-64]. But what can we reorder? At the very | ||
| 17 | // least we can safely reorder references to key schedule in respect | ||
| 18 | // to input and output streams. Secondly, from the first [close] glance | ||
| 19 | // it appeared that it's possible to pull up some references to | ||
| 20 | // elements of the key schedule itself. Original rationale ["prior | ||
| 21 | // loads are not safe only for "degenerated" key schedule, when some | ||
| 22 | // elements equal to the same value"] was kind of sloppy. I should have | ||
| 23 | // formulated as it really was: if we assume that pulling up reference | ||
| 24 | // to key[x+1] is not safe, then it would mean that key schedule would | ||
| 25 | // "degenerate," which is never the case. The problem is that this | ||
| 26 | // holds true in respect to references to key[x], but not to key[y]. | ||
| 27 | // Legitimate "collisions" do occur within every 256^2 bytes window. | ||
| 28 | // Fortunately there're enough free instruction slots to keep prior | ||
| 29 | // reference to key[x+1], detect "collision" and compensate for it. | ||
| 30 | // All this without sacrificing a single clock cycle:-) | ||
| 31 | // Furthermore. In order to compress loop body to the minimum, I chose | ||
| 32 | // to deploy deposit instruction, which substitutes for the whole | ||
| 33 | // key->data+((x&255)<<log2(sizeof(key->data[0]))). This unfortunately | ||
| 34 | // requires key->data to be aligned at sizeof(key->data) boundary. | ||
| 35 | // This is why you'll find "RC4_INT pad[512-256-2];" addenum to RC4_KEY | ||
| 36 | // and "d=(RC4_INT *)(((size_t)(d+255))&~(sizeof(key->data)-1));" in | ||
| 37 | // rc4_skey.c [and rc4_enc.c, where it's retained for debugging | ||
| 38 | // purposes]. Throughput is ~210MBps on 900MHz CPU, which is is >3x | ||
| 39 | // faster than gcc generated code and +30% - if compared to HP-UX C. | ||
