# While original submission covers 512- and 1024-bit exponentiation,
# this module is limited to 512-bit version only (and as such
# accelerates RSA1024 sign). This is because improvement for longer
# keys is not high enough to justify the effort, highest measured
# was ~5% on Westmere. [This is relative to OpenSSL 1.0.2, upcoming
# for the moment of this writing!] Nor does this module implement
# "monolithic" complete exponentiation jumbo-subroutine, but adheres
# to more modular mixture of C and assembly. And it's optimized even
# for processors other than Intel Core family (see table below for
# improvement coefficients).

Switch perlasm calling convention. Depending on architecture, perlasm differed on which one or both of: perl foo.pl flavor output.S perl foo.pl flavor > output.S Upstream has now unified on the first form after making a number of changes to their files (the second does not even work for their x86 files anymore). Sync those portions of our perlasm scripts with upstream and update CMakeLists.txt and generate_build_files.py per the new convention. This imports various commits like this one: 184bc45f683c76531d7e065b6553ca9086564576 (this was done by taking a diff, so I don't have the full list) Confirmed that generate_build_files.py sees no change.

*STDOUT=*OUT;
Get rid of all compiler version checks in perlasm files. Since we pre-generate our perlasm, having the output of these files be sensitive to the environment the run in is unhelpful. It would be bad to suddenly change what features we do or don't compile in whenever workstations' toolchains change or if developers do or don't have CC variables set. Previously, all compiler-version-gated features were turned on in https://boringssl-review.googlesource.com/6260, but this broke the build. I also wasn't thorough enough in gathering performance numbers. So, flip them all to off instead. I'll enable them one-by-one as they're tested. This should result in no change to generated assembly.
