Subject: [PATCH Rust front-end v3 04/46] gccrs: Add link cases testsuite
Date: Wed, 26 Oct 2022 10:17:29 +0200	[thread overview]
Message-ID: <20221026081811.602573-5-arthur.cohen@embecosm.com> (raw)
In-Reply-To: <20221026081811.602573-1-arthur.cohen@embecosm.com>

From: Philip Herron <philip.herron@embecosm.com>

This testsuite is heavily inspired from the lto testsuite which uses a
pattern that each file is compiled to an object file and finally linked
together. Since rust does not have headers/prototypes we rely on the
ordering here so that all files numbered greater than zero get compiled to
object files first leaving the _0 file free to test the 'extern crate' and
use keywords to force testing of the compiler to read metadata from the
other 'crates'.
