* Optimize D-Twist sparse Fp12 x line multiplication
* Move quadruple/octuple and add to Github issues: https://github.com/mratsim/constantine/issues/88 [skip ci]
* Pairing - initial commit
- line functions
- sparse Fp12 functions
* Small fixes:
- Line parametrized by twist for generic algorithm
- Add a conjugate operator for quadratic extensions
- Have frobenius use it
- Create an Affine coordinate type for elliptic curve
* Implement (failing) pairing test
* Stash pairing debug session, temp switch Fp12 over Fp4
* Proper naive pairing on BLS12-381
* Frobenius map
* Implement naive pairing for BN curves
* Add pairing tests to CI + reduce time spent on lower-level tests
* Test without assembler in Github Actions + less base layers test iterations
The running time of the test suite has increased significantly with:
- new tests (for example scalar mul implementations)
- new tests that stresses the whole stack/tower
- x3 randomizers for fuzzing
- new CI and platforms: Total 16x runs per commit
This would let all tests take less than 10 min on CI even non-parallelized one like on Windows.
* Clear cofactor in BN254 G2 testgen and frobenius
* Implement G2 endomorphism acceleration in Sage
* Somewhat working accelerated scalar mul G2 (2.2x) faster
- OK for BN254_Snarks
- Some test failing for BLS12-381
* Fix negative miniscalars by adding an extra bit of encoding
* Cleanup accel params
* Small recoding optimizations
* Fix 8x bigger than necessary encoding size of miniscalars in scalar mul
* initial windowed GLV-SAC implementation
* Simplify table encoding to match k0 without flipping bits
* Sage: Lattice decomp script fixes from anonymous reviewer
* update recoding mini test and add recoding primitives
* Update the GLV recoding
* update comments on positive/negative recoding [skip ci]
* sprinkle some {.noInit.} where possible
* Implement double-width field multiplication for double-width towering
* Fp2 mul acceleration via double-width lazy reduction (pure Nim)
* Inline assembly for basic add and sub
* Use 2 registers instead of 12+ for ASM conditional copy
* Prepare assembly for extended multiprecision multiplication support
* Add assembly for mul
* initial implementation of assembly reduction
* stash current progress of assembly reduction
* Fix clobbering issue, only P256 comparison remain buggy
* Fix asm montgomery reduction for NIST P256 as well
* MULX/ADCX/ADOX multi-precision multiplication

* Add (deactivated) assembly for double-width substraction + rework benches
* Add bench to nimble and deactivate double-width for now. slower than classic
* Fix x86-32 running out of registers for mul
* Clang needs to be at v9 to support flag output constraints (Xcode 11.4.2 / OSX Catalina)
* 32-bit doesn't have enough registers for ASM mul
* Fix again Travis Clang 9 issues
* LLVM 9 is not whitelisted in travis
* deactivated assembler with travis clang
* syntax error
* another
* ...
* missing space, yeah ...
