Subject: [COMMITTED] gccrs: rustc_attrs: Allow `rustc_inherit_overflow_checks` as a builtin..
Date: Tue, 31 Jan 2023 14:24:24 +0100 [thread overview]
Message-ID: <20230131132424.661382-1-arthur.cohen@embecosm.com> (raw)
..attribute. We cannot yet handle this attribute, but we should not reject it either
gcc/rust/ChangeLog:
* util/rust-attributes.cc: Add `rustc_inherit_overflow_checks` to list
of builtin attributes.
gcc/testsuite/ChangeLog:
* rust/compile/rustc_attr1.rs: New test.
Tested on x86_64-pc-linux-gnu, committed on master.
