That could be tmp += 4096 - sizeof(void*);

Where does the 70 come from ?

That can also be a single op.

I'll fix this your comments and some extra bugs in a new pull, just reject this one. |
|
You should push if instead once you've fixed everything (and squash commits). |
|
Test project /monero-m/build/Linux/master/debug It's passing cnv4jit test and the hash_slow4 test now, and x86 is unaffected. I guess its ready for merging. |
|
How long did the jit test take before that ? |
|
Double the time. I haven’t implemented altivec yet. For reference my xmrig fork went from 2 hash/s/core to 60 hash/s/core after optimizations. |
|
Can you squash those commits please ? |
|
Hmm, how do I that? I just tried and it added two more commits. |
|
Meh, I'll just delete the repo and refork, dunno what I did wrong. |

+duplicate of #5543 |
Initial version of JIT compiler for PPC, ported from my fork of XMRIG. Still requires testing.
