These operations are not available on the thumbv6m-none-eabi target:

  • f64 as i64
  • f64 as u64
  • f64 == f64
  • f64 > f64
  • f64 < f64
  • f32 as i64
  • f32 as u64
  • f32 == f32
  • f32 > f32
  • f32 < f32

and won't be available until these intrinsics:

  • __aeabi_dcmpeq
  • __aeabi_dcmpgt
  • __aeabi_dcmple
  • __aeabi_dcmplt
  • __aeabi_fcmpeq
  • __aeabi_fcmpgt
  • __aeabi_fcmple
  • __aeabi_fcmplt

are ported to Rust because compiler-rt doesn't provide an implementation of these for the thumbv6m-none-eabi target.

Should this now be closed?
#276 removed the thumbv6m config from the intrinsics example.
