Comment (by cal@…):

 Yes, this is all Perl code that compares compiler version numbers to find
 out whether AVX or the addx instruction are available. Why the OpenSSL
 project has literally (at least) 13 copies of the some code is beyond me.
 I also don't understand why they compare version macros rather than just,
 say, run an AVX or addx instruction through to toolchain to see if it
 works.

 I'm not in the business of refactoring OpenSSL code in what seems to be
 rather large endeavor.

 You can use the OpenSSL test suite to check whether the code miscompiles
 with the change. Additionally, compare the output of `openssl speed` with
 that of 1.0.2d on 10.7, that should give you a rough idea whether it is
 using the same assembler optimizations.
