Struct SubprogramInfo 

pub struct SubprogramInfo {
    pub name: String,
    pub low_pc: u64,
    pub high_pc: u64,
}

One function to describe with a DW_TAG_subprogram child DIE (#394, Tier-1) so a debugger backtrace shows the FUNCTION NAME, not a bare address. Carries the function’s name and its object-relative [low_pc, high_pc) .text range (byte offsets against the .text base). The emitter relocates low_pc against the SAME .text symbol as the CU (addend = low_pc) and writes high_pc - low_pc as the offset form of DW_AT_high_pc (no relocation).

Fields

name: String

The function name shown in a debugger frame. The caller composes it with priority name-section name > export name > synthetic func_N (#394 Tier-1.x), so internal functions carry their real developer-facing name (e.g. core::panicking::panic_fmt::h...) whenever the input wasm has a name custom section.

low_pc: u64

Object-relative .text byte offset of the function’s first instruction.

high_pc: u64

Object-relative .text byte offset one past the function’s last byte.
