# Multi-module linking.
|

#
|
|
# Modules are only testable end to end, and nothing else in the suite
|
|
# links more than one translation unit. Three things have to hold at
|
|
# once: an imported `pub fn' comes out as a prototype with external
|
|
# linkage, an imported `pub var' as an extern declaration, and the
|
|
# module's object survives being passed after `--'. Get any of them
|
|
# wrong and this fails to link -- or, in the `pub var' case, links and
|
|
# quietly counts into a private copy.
|
|
#
|
|
# It also checks what only a second translation unit can check: that an
|
|
# imported type reaches the type database, by expanding a macro that
|
|
# reads the imported struct's fields.
