ICE: invalid asymmetric binary op #121534
Description
auto-reduced (treereduce-rust):
union union { union: u32, inion: i32, u8ion: u8, i64on: i64, u64on: u64, } pub fn main() { let union = union { union: 2 }; let inion = union { inion: -2 }; let mut mnion = union { inion: -16 }; let m1 = unsafe { mnion.union }; let u1 = unsafe { union.union }; let u2 = unsafe { inion.union }; let _r1 = u2 - u1 - m1; } original (gcc/testsuite/rust/compile/torture/union_union.rs) :
union union { union: u32, inion: i32, u8ion: u8, i64on: i64, u64on: u64 } pub fn main () { let union = union { union: 2 }; let inion = union { inion: -2 }; let mut mnion = union { inion: -16 }; let m1 = unsafe { mnion.union }; unsafe { mnion.union = union.union }; let m2 = unsafe { mnion.inion }; let u1 = unsafe { union.union }; let i1 = unsafe { union.inion }; let u2 = unsafe { inion.union }; let i2 = unsafe { inion.inion }; let _r1 = u2 - u1 - m1; let _r2 = i1 + i2 + m2; let _u8 = unsafe { union.u8ion }; let _i64 = unsafe { union.i64on }; let _u64 = unsafe { union.u64on }; }Version information
