build error on MacOS/ARM 3.8 #115
Milestone
Comments
|
We haven't tested it on macos/ARM since we don't have access to an ARM64 mac (yet), so it is not supported yet, but we would like to support it. I made PR #116 which should fix the issue by disabling SSE2 and AVX2 on |
|
I made a successful test build using commit f1768e0 (post-116-merge) in conda-forge/hdf5plugin-feedstock#21, so I assume this ticket can be closed. Do you know when the next release of hdf5plugin will happen? |
|
Thanks for the testing! With M1 support fixed we should make a release soon. closed by PR #116 |

We now store len - offset in a signed int16, this happens to remove masking offset in the calculations and the calculations that need to be done precisely give the flags that we need for testing correctness. 2) Replace offset extraction with a lookup mask. This is less uops and is needed because we need to special case type 3 to always return 0 as to properly trigger the fallback. 3) Unroll the loop twice, this removes some loop-condition checks AND it improves the generated assembly. The loop variables tend to end up in a different register requiring mov's having two consecutive copies allows the elision of the mov's.

Due to the long dependency chain the CPU is running with IPC~1 anyway so we can freely add instructions to instead emit copies branchfree.

There is enough bandwidth to do so in the intrinsic cycles of the loop. 4) Implement limit pointers that include the slop region. This removes unnecessary instructions from the hot path. 5) It seems the removal of the difficult to predict branch has removed the code sensitivity to alignment, so remove the asm nop's.

I'm trying to build hdf5plugin 2.3.2 on MacOS on ARM64 for conda-forge (conda-forge/hdf5plugin-feedstock#20), and I see the following build error:
Is MacOS/ARM supported by hdf5plugin?
The text was updated successfully, but these errors were encountered:
