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
