Bug ID: 96341
Summary: Support mixed element widths for AArch64 "omp declare
simd" functions
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: rsandifo at gcc dot gnu.org
Target Milestone: ---
Target: aarch64*-*-*
aarch64_simd_clone_compute_vecsize_and_simdlen currently rejects
functions that operate on a mixture of element sizes. However,
the ABI has rules to handle those cases too. See:
https://github.com/ARM-software/abi-aa/tree/master/vfabia64
for the full specification. We should remove the current
restriction and handle mixed sizes in accordance with the
ABI rules.
