| 5 # project. The module is, however, dual licensed under OpenSSL and |

| 10 # I let hardware handle unaligned input, except on page boundaries |
| 11 # (see below for details). Otherwise straightforward implementation |
| 12 # with X vector in register bank. The module is big-endian [which is |
| 13 # not big deal as there're no little-endian targets left around]. |

| 21 # (*) 64-bit code in 32-bit application context, which actually is |
| 22 # on TODO list. It should be noted that for safe deployment in |
| 23 # 32-bit *mutli-threaded* context asyncronous signals should be |
| 24 # blocked upon entry to SHA512 block routine. This is because |
| 25 # 32-bit signaling procedure invalidates upper halves of GPRs. |
| 26 # Context switch procedure preserves them, but not signaling:-( |
| 27 |
| 28 # Second version is true multi-thread safe. Trouble with the original |
| 29 # version was that it was using thread local storage pointer register. |
| 30 # Well, it scrupulously preserved it, but the problem would arise the |
| 31 # moment asynchronous signal was delivered and signal handler would |
| 32 # dereference the TLS pointer. While it's never the case in openssl |
| 33 # application or test suite, we have to respect this scenario and not |
| 34 # use TLS pointer register. Alternative would be to require caller to |
| 35 # block signals prior calling this routine. For the record, in 32-bit |
| 36 # context R2 serves as TLS pointer, while in 64-bit context - R13. |
