Subject: [RFC PATCH 03/10] arm: exclude eabi_compat from LTO
Date: Sat, 20 May 2023 14:55:40 -0600 [thread overview]
Message-ID: <20230520205547.1009254-4-CFSworks@gmail.com> (raw)
In-Reply-To: <20230520205547.1009254-1-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).
