__elephc_ptr_is_null() — internals

Where it lives

• Signature: src/builtins/pointers/__elephc_ptr_is_null.rs
• Lowering: src/codegen/lower_inst/builtins/pointers.rs:51 (lower_ptr_is_null)
• Function symbol: lower_ptr_is_null()

Lowering notes

• Lowers ptr_is_null(pointer) by comparing the raw pointer address to zero.

Runtime helpers

Eval interpreter (magician)
