Abd ar-Rahman Hamidi	db87223269	crypto/secp256k1: add checking z sign in affineFromJacobian (#18419) ... The z == 0 check is hit whenever we Add two points with the same x1/x2 coordinate. crypto/elliptic uses the same check in their affineFromJacobian function. This change does not affect block processing or tx signature verification in any way, because it does not use the Add or Double methods.	4 years ago

Felix Lange	5f7826270c	all: unify big.Int zero checks, use common/math in more places (#3716) ... * common/math: optimize PaddedBigBytes, use it more name old time/op new time/op delta PaddedBigBytes-8 71.1ns ± 5% 46.1ns ± 1% -35.15% (p=0.000 n=20+19) name old alloc/op new alloc/op delta PaddedBigBytes-8 48.0B ± 0% 32.0B ± 0% -33.33% (p=0.000 n=20+20) * all: unify big.Int zero checks Various checks were in use. This commit replaces them all with Int.Sign, which is cheaper and less code. eg templates: func before(x *big.Int) bool { return x.BitLen() == 0 } func after(x *big.Int) bool { return x.Sign() == 0 } func before(x *big.Int) bool { return x.BitLen() > 0 } func after(x *big.Int) bool { return x.Sign() != 0 } func before(x *big.Int) int { return x.Cmp(common.Big0) } func after(x *big.Int) int { return x.Sign() } * common/math, crypto/secp256k1: make ReadBits public in package math	8 years ago
