* sha/asm/keccak1600-s390x.pl: resolve -march=z900 portability issue.Andy Polyakov2018-10-121-2/+2
| | | | | | | | | | | Negative displacement in memory references was not originally specified, so that for maximum coverage one should abstain from it, just like with any other extension.

* Harmonize the make variables across all known platforms familiesRichard Levitte2018-02-141-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | The make variables LIB_CFLAGS, DSO_CFLAGS and so on were used in addition to CFLAGS and so on. This works without problem on Unix and Windows, where options with different purposes (such as -D and -I) can appear anywhere on the command line and get accumulated as they come. This is not necessarely so on VMS. For example, macros must all be collected and given through one /DEFINE, and the same goes for inclusion directories (/INCLUDE). So, to harmonize all platforms, we repurpose make variables starting with LIB_, DSO_ and BIN_ to be all encompassing variables that collects the corresponding values from CFLAGS, CPPFLAGS, DEFINES, INCLUDES and so on together with possible config target values specific for libraries DSOs and programs, and use them instead of the general ones everywhere. This will, for example, allow VMS to use the exact same generators for generated files that go through cpp as all other platforms, something that has been impossible to do safely before now.

| | | | | | | | | | | | | | | | | ... script data load. On related note an attempt was made to merge rotations with logical operations. I mean as we know, ARM ISA has merged rotate-n-logical instructions which can be used here. And they were used to improve keccak1600-armv4 performance. But not here. Even though this approach resulted in improvement on Cortex-A53 proportional to reduction of amount of instructions, ~8%, it didn't exactly worked out on non-Cortex cores. Presumably because they break merged instructions to separate μ-ops, which results in higher *operations* count. X-Gene and Denver went ~20% slower and Apple A7 - 40%. The optimization was therefore dismissed. Reviewed-by: Rich Salz <rsalz@openssl.org>

| | | | | | | | | | | | | | | | | | "Optimize" is in quotes because it's rather a "salvage operation" for now. Idea is to identify processor capability flags that drive Knights Landing to suboptimial code paths and mask them. Two flags were identified, XSAVE and ADCX/ADOX. Former affects choice of AES-NI code path specific for Silvermont (Knights Landing is of Silvermont "ancestry"). And 64-bit ADCX/ADOX instructions are effectively mishandled at decode time. In both cases we are looking at ~2x improvement. AVX-512 results cover even Skylake-X :-) Hardware used for benchmarking courtesy of Atos, experiments run by Romain Dolbeau <romain.dolbeau@atos.net>.
