Now that BIP66 passed, OpenSSL is no longer directly part of the
consensus. What matters is that DER signatures are correctly parsed, and
secp256k1 crypto is implemented correctly (as well as the other
functions we use from OpenSSL, such as random number generation)
This means that effectively, using LibreSSL is not a larger risk than
using another version of OpenSSL.
Remove the specific check for LibreSSL.
Includes the still-relevant part of #6729: make sure CHECK_HEADER is
called using the right CXXFLAGS, not CFLAGS (as AC_LANG is c++).
Benchmarking framework, loosely based on google's micro-benchmarking
library (https://github.com/google/benchmark)
Wny not use the Google Benchmark framework? Because adding Even More Dependencies
isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate
timings of threaded code then switching to the full-blown Google Benchmark library
should be considered.
The benchmark framework is hard-coded to run each benchmark for one wall-clock second,
and then spits out .csv-format timing information to stdout. It is left as an
exercise for later (or maybe never) to add command-line arguments to specify which
benchmark(s) to run, how long to run them for, how to format results, etc etc etc.
Again, see the Google Benchmark framework for where that might end up.
See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks
'sleep 100 milliseconds.'
To compile and run benchmarks:
cd src; make bench
Sample output:
Benchmark,count,min,max,average
Sleep100ms,10,0.101854,0.105059,0.103881

Bugfix: Add missing zmq header includes
Bugfix: Adjust build system to link ZeroMQ code for Qt binaries
Checking libcrypto for a function after we've already found a (possibly
different) libcrypto is not what we want to do here.
pkg-config might've found a cross lib while AC_CHECK_LIB may find a different
or native one.
Run a link-test against the lib that's already been found instead.
Three changes to how configure --enable-debug behaves:
1. Preserve user-passed CXXFLAGS/CFLAGS
2. Compile with -DDEBUG_LOCKORDER
3. Add -DDEBUG -DDEBUG_LOCKORDER to CPPFLAGS (since they are preprocessor options)
Until secp256k1 is used for verification there is no reason for Bitcoin
Core's secp256k1 to link against gmp, even if available. Pass a flag to
configure to override the bignum implementation.
This fixes a crash at runtime on ppc64 reported by @gmaxwell.

- Detect endian instead of stopping configure on big-endian

- Update `crypto/common.h` functions to use compat
endian header
This was added a while ago for testing purposes, but was never intended to be
used. Remove it until upstream libsecp256k1 decides that verification is
stable/ready.
Backwards-compatibility for libstdc++ is not limited to straightforward abi
changes. Symbol visibility also needs to be taken into consideration, and
that really can't be addressed simply.
Instead, just static-link libstdc++ for backwards-compat.
This is really a packager's option. While it's helpful to encourage devs to
test this option for daily builds, it's not reliable in several real-world
use-cases. Some older libstdc++ runtimes (freebsd 9, debian wheezy, for
example) fail to properly catch exceptions due to mismatched type_info.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=19664 for more info.
