Revision 6ecdcbd707cac5d9831d9614d025d33e43b20a8f authored by Steven Johnson on 11 December 2022, 18:05:55 UTC, committed by GitHub on 11 December 2022, 18:05:55 UTC
This makes a couple of changes to the behavior/implementation of `halide_malloc()`: * Currently, halide_malloc must return a pointer aligned to the maximum meaningful alignment for the platform for the purpose of vector loads and stores. This PR also adds the requirement that the memory returned must be legal to access in an integral multple of alignment >= the requested size (in other words: you should be able to do vector load/stores "off the end" without causing any faults). * Currently, the `halide_malloc_alignment()` function is used to determine the default alignment; this cannot be overridden by user code (well, it can be, but the override will have no useful effect). It is intended to be "internal only" but is used in at least one place outside the runtime (apps/hannk). This change removes the call entirely, in favor of a call that is harder to access from outside the runtime and much less likely for end users to attempt to call. (It also changes apps/hannk to stop using it.)

# NOTE: one can debug these rules with the following commands:
#
# $ git clean -ffdx
# $ find . -not -path './.git/*' | git check-ignore --stdin --no-index
#
# The first command will delete all files that are ignored by Git (be warned!).
# The second command will print all files that are checked in, but _would be_
# ignored under the rules in this file. Such files should either be explicitly
# added to the exclusions at the bottom of this file, or the rule excluding them
# should be refined.
