Subject: [PATCH Rust front-end v2 06/37] gccrs: Add execution test cases
Date: Wed, 24 Aug 2022 12:59:25 +0100 [thread overview]
Message-ID: <20220824115956.737931-7-philip.herron@embecosm.com> (raw)
In-Reply-To: <20220824115956.737931-1-philip.herron@embecosm.com>
From: Philip Herron <philip.herron@embecosm.com>
This is similar to the compile/torture/*.rs test cases but all of these are
dg-execute testcases so they get compiled, linked and executed by default,
all the while being compiled with the matrix of torture options.
The only caveat here is that currently gccrs does not currently support
the main shim yet so we have a C-style main function here returning zero
which is not supported in Rustc.
