From: Pierre-Emmanuel Patry <[email protected]>
The compiler would crash if the file name was requested from the lexer
whilst lexing from a non-file source (mainly string sources). Now return
an empty file name instead.
gcc/rust/ChangeLog:
* lex/rust-lex.h: Return an empty file name when file is missing.
