Mark Thom 9366a48d6d introduce InlineTermStream to avoid arena allocations during call_inline (#1576) 2022-11-09 00:01:01 +01:00
Markus Triska d91ee5b77c FIXED: CLP(ℤ): Correctly remove all attributes during propagation of all_distinct/1 and other global constraints. 
The constraints from library(clpz) were already correctly removed, but
others such as pending freeze/2 goals were not, potentially leading to
an accumulation of redundant constraints during propagation.

Test case:

   ?- freeze(A,(X=1;X=2)), all_distinct([A]), A = 1.
      A = 1, X = 1
   ;  A = 1, X = 2.

The combination of freeze/2 and CLP(ℤ) is useful for example when
creating animations of search processes.

This addresses #1624.

Mark Thom 140149f051 fix crash in read_term (#1616) 2022-10-26 23:36:07 -06:00
Markus Triska b2cccab768 ENHANCED: library(crypto): Faster conversion to bytes when the integer is known. 
These entailed constraints only affect performance, and can be removed
without affecting the correctness of the code. They speed up scalar
multiplication of a curve point, used for example in Bitcoinolog.

Markus Triska 9c2cb144b5 remove redundant error handling, since this case is checked in Prolog 
This restores f668640e3d, where this
change was already made. It seems it was accidentally overwritten in
0404c3bd94.

Markus Triska 9c1de8e00b ENHANCED: Eliminate the OpenSSL dependency of library(crypto). 
This is achieved by using the newly available crrl crate by @pornin
to implement crypto_curve_scalar_mult/4 for secp256k1. Many thanks!

Markus Triska 1e018681de ENHANCED: Much improved nth0/3, taken from #1529. 
This also adds nth0/4 and bootstraps nth1/[3,4] from it.
