e2d66a2 Fix build for 64bit field under OSX (Peter Dettman)
 2014-11-03 00:44:44 -08:00
Peter Dettman e2d66a2c62 Fix build for 64bit field under OSX 
- caused by 8881212ebc
- OSX's ar tool doesn't work for empty archives ("ar: no archive members specified")
- introduce COMMON_LIB variable; leave empty when not using asm

Pieter Wuille 7a8e385d74 Fix interaction between magnitudes and negation 
Magnitude m means values are allowed to be up to 2 * 0xFFF...FFF * m,
while the argument passed to secp256k1_fe_negate didn't take the 2 into
account. Fix this.

c259a7c Set precomputation table late and unset early. (Pieter Wuille)
04e34d1 Split up signing and verification initialization (Pieter Wuille)
 2014-09-28 06:00:31 +02:00
Pieter Wuille c259a7cbc0 Set precomputation table late and unset early. 
Set the global pointer to the precomputation table only after initializing
it completely, and unset it before doing any uninitialization.

This causes fail-fast behavior in case of race conditions between
initialization and operations using it.
