- Authentication-results: sourceware.org; auth=none
While doing some benchmark flag mining on AArch64, I noticed that
-fpeel-loops was a mined option often. As a matter of fact, when using it
always, even without FDO, it seemed to raise most benchmarks and to leave
almost all of the rest flat, with a barely noticeable cost in code-size. It
seems to me that it might be safe enough to be implied perhaps at -O3. Is
there any reason why this never came into being?
