Bug ID: 96340
Summary: Extend AArch64 "omp declare simd" support to general
simdlen
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: ---
aarch64_simd_clone_compute_vecsize_and_simdlen currently requires
the simdlen to give a natural Advanced SIMD type. However, the ABI
handles any power of 2, including smaller-than-64-bit lengths and
larger-than-128-bit lengths. See:
https://github.com/ARM-software/abi-aa/tree/master/vfabia64
for the full specification. We should remove the current
restriction and handle other lengths in accordance with the
ABI rules.
