Before: test_cn_fast_hash<32> (100000 calls) - OK: 1 us/call test_cn_fast_hash<16384> (1000 calls) - OK: 164 us/call After: test_cn_fast_hash<32> (100000 calls) - OK: 0 us/call test_cn_fast_hash<16384> (1000 calls) - OK: 31 us/call More than 5 times speedup for cn_fast_hash. Also noticed consistent 1-2% improvement in test_construct_tx results. keccak: remove aligned check 2020-05-16T12:28:27Z moneromooo-monero moneromooo-monero@users.noreply.github.com 2020-05-16T12:27:22Z urn:sha1:7178bb5c848bca3996dba98f82c757c357b58934 Some tools report the alignment check as UB, which seems a bit dubious, but since the performance difference between the two versions is minimal, I'll go with the safe version keccak: guard against misaligned memory accesses on ARM 2019-07-04T22:13:16Z moneromooo-monero moneromooo-monero@users.noreply.github.com 2019-07-02T21:07:49Z urn:sha1:c2238327d0c20f2a1e601ec120db51a13cebfc35 The code generated is exactly the same as the direct access one on x86_64 ensure no NULL is passed to memcpy 2019-06-14T08:47:29Z moneromooo-monero moneromooo-monero@users.noreply.github.com 2019-04-29T08:17:32Z urn:sha1:0564da5fdc165948ba7c862fb81478f9287a072d NULL is valid when size is 0, but memcpy uses nonnull attributes, so let's not poke the bear move int-util.h to epee 2018-12-04T15:14:29Z moneromooo-monero moneromooo-monero@users.noreply.github.com 2018-11-18T10:17:24Z urn:sha1:ec1a62b50dedb65f14db30dbafb1035018cf3421 crypto: fixed incremental keccak API on big-endian platforms 2018-10-22T15:34:19Z xiphon xiphon@protonmail.com 2018-10-22T06:48:54Z urn:sha1:ed36335c969a1061e555724467263e22d1738cce Fixed Keccak implementation on big-endian platforms 2018-09-17T16:24:20Z Alexandro Sanchez alexandro@phi.nz 2018-09-17T14:32:55Z urn:sha1:9bf0105e251fdedb5bd2cc2f04d99339d640f0af Incremental Keccak API added 2018-08-15T16:20:22Z Dusan Klinec dusan.klinec@gmail.com 2018-08-14T21:23:00Z urn:sha1:4e081001c007178d9d970219c14ae78afd9a6935 - needed for TREZOR integration Merge pull request #3226 2018-02-16T13:26:58Z Riccardo Spagni ric@spagni.net 2018-02-16T13:26:58Z urn:sha1:f4a6bc79d9a751480597aa007a1c6d315604f856 e4646379 keccak: fix mdlen bounds sanity checking (moneromooo-monero) 2e3e90ac pass large parameters by const ref, not value (moneromooo-monero) 61defd89 blockchain: sanity check number of precomputed hash of hash blocks (moneromooo-monero) 9af6b2d1 ringct: fix infinite loop in unused h2b function (moneromooo-monero) 8cea8d0c simplewallet: double check a new multisig wallet is multisig (moneromooo-monero) 9b98a6ac threadpool: catch exceptions in dtor, to avoid terminate (moneromooo-monero) 24803ed9 blockchain_export: fix buffer overflow in exporter (moneromooo-monero) f3f7da62 perf_timer: rewrite to make it clear there is no division by zero (moneromooo-monero) c6ea3df0 performance_tests: remove add_arg call stray extra param (moneromooo-monero) fa6b4566 fuzz_tests: fix an uninitialized var in setup (moneromooo-monero) 03887f11 keccak: fix sanity check bounds test (moneromooo-monero) ad11db91 blockchain_db: initialize m_open in base class ctor (moneromooo-monero) bece67f9 miner: restore std::cout precision after modification (moneromooo-monero) 1aabd14c db_lmdb: check hard fork info drop succeeded (moneromooo-monero) keccak: fix mdlen bounds sanity checking 2018-02-07T13:39:32Z moneromooo-monero moneromooo-monero@users.noreply.github.com 2018-02-07T13:39:32Z urn:sha1:e4646379a6fb5d1dcff71cc38db5e60802a21dcb found by h908714124
