This is purported to save a few cycles, but makes the code less obvious and more brittle, and in fact breaks on platforms where for ABI continuity reasons there is a SHA2 implementation in libc, and so EVP needs to call those to avoid conflicts. A sufficiently good optimizer could simply generate the same entry points for: foo(...) { ... } and bar(...) { return foo(...); } but, even without that, the different is negligible, with the "winner" varying from run to run (openssl speed -evp sha384): Old: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes sha384 28864.28k 117362.62k 266469.21k 483258.03k 635144.87k 649123.16k New: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes sha384 30055.18k 120725.98k 272057.26k 482847.40k 634585.09k 650308.27k Reviewed-by: Rich Salz <rsalz@openssl.org> |
