Expand description

ADR-0085: a body-less extern fn declared inside a link_extern("…") { … } block.

These are tracked as a side-set on the Rir rather than as FnDecl instructions because their lowering pipeline diverges from regular fns: no body to translate, no Gruel mangling, library name to thread through to the linker.

Fields§

§library: Spur

Library name (interned, as written in the link_extern("…") head).

§name: Spur

Function name (as it appears in Gruel source).

§directives_start: u32

Index into the extra array where this fn’s directives start.

§directives_len: u32

Number of directives.

§params_start: u32

Index into the extra array where this fn’s params start.

§params_len: u32

Number of parameters.

§return_type: Spur

Return type as a Spur (defaults to () when omitted in source).

§span: Span

Span of the fn declaration.

§block_span: Span

Span of the enclosing link_extern(...) block.

§link_mode: RirLinkMode

ADR-0086: dynamic (link_extern) vs static (static_link_extern).
