Test Case

(module
  (func (export "ceil") (param $x f32) (result f32) (f32.ceil (local.get $x)))
  (func (export "floor") (param $x f32) (result f32) (f32.floor (local.get $x)))
  (func (export "trunc") (param $x f32) (result f32) (f32.trunc (local.get $x)))
  (func (export "nearest") (param $x f32) (result f32) (f32.nearest (local.get $x)))
)

Steps to Reproduce

Expected Results

The expected relocation type is R_X86_64_64, indicating a 64-bit absolute relocation.

Yeah looks like a bug, thanks! Would you be up for sending a PR to update that constant? I believe an update will be required here as well.
