Bug ID: 34284
Summary: __builtin_cpu_supports does not work on ARM
Assignee: unassignedbugs at nondot.org
Reporter: gonzalobg88 at gmail.com
CC: llvm-bugs at lists.llvm.org
I'd like to be able to detect whether an ARM CPU supports Neon vector
instructions using __builtin_cpu_supports("neon") or similar but it seems that
compiler-rt only supports x86_64.
