Subject: [PATCH liburing v2 1/4] src/Makefile: Remove `-fomit-frame-pointer` from default build
Date: Thu, 10 Mar 2022 10:32:21 +0000 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
-fomit-frame-pointer is already turned on by -O1 optimization flag.
The liburing default compilation uses -O2 optimization, -O2 turns on
all optimization flags specified by -O1. Therefore, we don't need to
specify -fomit-frame-pointer here. Remove it.
