:wave: Hey,
This came up when trying to fuzz #4884 on AArch64
.clif
Test Casetest run target aarch64 function %a(i128) -> f32 { block0(v0: i128): v1 = fcvt_from_uint.f32 v0 return v1 } ; run: %a(0) == 0.0 function %c(i128) -> f64 { block0(v0: i128): v1 = fcvt_from_uint.f64 v0 return v1 } ; run: %c(0) == 0.0 function %signed_a(i128) -> f32 { block0(v0: i128): v1 = fcvt_from_sint.f32 v0 return v1 } ; run: %signed_a(0) == 0.0 function %signed_c(i128) -> f64 { block0(v0: i128): v1 = fcvt_from_sint.f64 v0 return v1 } ; run: %signed_c(0) == 0.0
Steps to Reproduce
clif-util ./the-above.clif
Expected Results
The above tests to pass.
Actual Results

This fails in the first function but all the functions in all test cases crash with a similar error.
