Thanks to Arimin and Brian Kearns. They fixed unaligned memory access, now ARM micronumpy no longer crashes during testing. Matti On 02/23/2014 11:43 AM, Armin Rigo wrote:
I've checked in some new code in rawstorage.py on default: raw_storage_{get,set}item_unaligned(). It's regular RPython code that checks if the argument is aligned or not, and if not, it falls back to a memcpy(). It should be relatively jit-friendly. Note that I also changed the non-unaligned functions so that, when untranslated, they complain if the address is unaligned, whatever the platform.
Can you try to change some or all of the raw_storage_{get,set}item() calls in micronumpy? I don't really know which ones are at a risk of seeing unaligned accesses, and which ones not. It seems that all of them are at risk: see the failure in test_numarray.AppTestRecordDtype.test_string_record.
A bientôt,
Armin.
