402878ae11 fix ifdef/ifndef 2015-01-23 17:09:50 -05:00
Gregory Maxwell
25b35c7ecb Convert field code to strict C89 (+ long long, +__int128) 
This makes the software more portable to embedded systems
 and static analysis tools.

Sadly, it can't result in identical binaries because C99 mixed
 declarations seem to make GCC emit superfluous stack-pointer
 updates. The compiler is also somewhat dependent on the
 declaration order.

70ae0d2851 Use secp256k1_fe_equal_var in secp256k1_fe_sqrt_var. 
In theory this should be faster, since secp256k1_fe_equal_var is able to
 shortcut the normalization.  On x86_64 the improvement appears to be in
 the noise for me.  At least it makes the code cleaner.

d26e26f Avoid constructing an invalid signature with probability 1:2^256. (Gregory Maxwell)
 2014-12-29 17:51:40 +01:00
Pieter Wuille
9ab93355f2 Add a reference consistency test to ge_tests. 
This adds all points used in the test together in random order, which
should result in infinity.

Suggested by Greg Maxwell.
