From: Pierre-Emmanuel Patry <[email protected]>
Extern block metadata is required to identify intrinsics from an extern
crate.
gcc/rust/ChangeLog:
* metadata/rust-export-metadata.cc (ExportContext::begin_extern_block):
Dump the prefix of an extern block.
(ExportContext::end_extern_block): Likewise with extern block suffix.
* metadata/rust-export-metadata.h: Add function prototypes.
