* Use FORTIFY_SOURCE for testing
* Fix#230 - gcc miscompiles Fp6 mul with LTO
* disable LTO for now, PR is too long
* try parallel reduction in batch add, but alas it's slower than custom chunking. Except maybe on arch with performance/efficiency cores
* initial impl of parallel MSM - scaling to debug, threads not woken fast enough
* improve comment [skip ci]
* skip top window when c divides the number of bits
* for some reason parallel-for loops scale on 5+ threads while spawn only on 2x threads. Thread wakeup issue?
* Add counters and timers to audit threadpool bottlenecks

* fix thief thread trying to wake another before canceling its own sleep
* easier to sort metrics and parallel endomorphism application
* selective endomorphism acceleration
* some tuning
* spawn can handle compile-time literals, static and type parameters. Also introduce spawnAwaitable to await void procs
* improve MSM overview [skip ci]
* bench cleanup
* Threadpool: eventcount didn't put threads to actual sleep :/
* rework task awaiter sleep to prevent use-after-free race condition after task completion
* Need memory fence for StoreLoad synchronization ordering
* update design doc
* set memory order in sleep of eventcount
* cleanup debug logs
* comment cleanup [skip ci]
* remove reserve threads
* recover last perf diff: 1. don't import primitives, cpu features detection globals are noticeable, 2. noinit + conditional zeroMem are unnecessary when sync is inline 3. inline 'newSpawn' and don't init the loop part
* avoid syscalls if possible if thred is awake but idle
* renaming eventLoop
* remove unused code: steal-half
* renaming
* no need for 0-init sync, T can be large in cryptography
* introduce reserve threads to minimize latency and maximize throughput when awaiting a future
* introduce a ceilDiv proc
* threadpool: implement parallel-for loops
* 10x perf improvement by not waking reserveBackoff on syncAll
* bench overhead: new reserve system might introduce too much wakeup latency, 2x slower, for fine-grained parallelism
* add parallelForStrided
* Threadpool: Implement parallel reductions
* refactor parallel loop codegen: introduce descriptor, parsing and codegen stages
* parallel strided, test transpose bench
* tight loop is faster when backoff is not inline
* no POSIX stuff on windows, larger types for histogram bench
* fix tests
* max RSS overflow?
* missed an undefined var
* exit histogram on 32-bit
* forgot to return early dor 32-bit
* unoptimized msm

* common msm bench + don't use affine for c < 9
* nit
* create a codecs.nim file for hex/base64 and other encoding conversions
* improve maintenance/readability of hex conversion
* add skeleton of constant-time base64 decoding
* use raw casts

* [Threadpool] Fix syncAll releasing while a thread was attempting to steal + force no exception in tasks
* fix unguarded access on MacOS barriers
* parallel batchadd
* moved import
* Implement a threadpool
* int and SomeUnsignedInt ...
* Type conversion for windows SynchronizationBarrier
* Use the latest MacOS 11, Big Sur API (jan 2021) for MacOS futexes, Github action offers MacOS 12 and can test them
* bench need posix timer not available on windows and darwin futex
* Windows: nimble exec empty line is an error, Mac: use defined(osx) instead of defined(macos)
* file rename
* okay, that's the last one hopefully
* deactivate stealHalf for now

* sha256: Fix reworked update function
* Implement x86 hardware SHA acceleration
* typo
