Subject: [PATCH v2 02/15] arm: Exclude eabi_compat from LTO
Date: Sat, 15 Mar 2025 15:18:00 -0700 [thread overview]
Message-ID: <20250315221813.1265193-3-CFSworks@gmail.com> (raw)
In-Reply-To: <20250315221813.1265193-1-CFSworks@gmail.com>
These symbols need to survive the IR-level dead function elimination pass,
since nothing at the IR level is referencing them (calls to these are inserted
later, at codegen time).
