[PATCH] misc: only build with lto if explicitly enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Change the LTO default to off from probe because it wastes build time on
developer machines.  Anyone who really wants it for release builds or
whatever can still turn it on.
