Mamy Ratsimbazafy	5806cc4638	Double-Precision towering (#155) ... * consistent naming for dbl-width * Isolate double-width Fp2 mul * Implement double-width complex multiplication * Lay out Fp4 double-width mul * Off by p in square Fp4 as well :/ * less copies and stack space in addition chains * Address https://github.com/mratsim/constantine/issues/154 partly * Fix #154, faster Fp4 square: less non-residue, no Mul, only square (bit more ops total) * Fix typo * better assembly scheduling for add/sub * Double-width -> Double-precision * Unred -> Unr * double-precision modular addition * Replace canUseNoCarryMontyMul and canUseNoCarryMontySquare by getSpareBits * Complete the double-precision implementation * Use double-precision path for Fp4 squaring and mul * remove mixin annotations * Lazy reduction in Fp4 prod * Fix assembly for sum2xMod * Assembly for double-precision negation * reduce white spaces in pairing benchmarks * ADX implies BMI2	2021-02-09 22:57:45 +01:00
Mamy Ratsimbazafy	638cb71e16	Fr: Finite Field parametrized by the curve order (#115) ... * Introduce Fr type: finite field over curve order. Need workaround for https://github.com/nim-lang/Nim/issues/16774 * Split curve properties into core and derived * Attach field properties to an instantiated field instead of the curve enum * Workaround https://github.com/nim-lang/Nim/issues/14021, yet another "working with types in macros" is difficult https://github.com/nim-lang/RFCs/issues/44 * Implement finite field over prime order of a curve subgroup * skip OpenSSL tests on windows	2021-01-22 00:09:52 +01:00
