Subject: Backport of commit a75bb4eb9e565b9f5115e2e8c07377ce32cbe69a
Date: Tue, 23 Apr 2019 12:04:21 -0700	[thread overview]
Message-ID: <20190423190426.18720-1-natechancellor@gmail.com> (raw)

Hi Greg and Sasha,

Please apply this commit to 4.4 through 5.0 (patches are threaded in
reply to this one), which will prevent Clang from emitting references
to compiler runtime functions and doing some performance-killing
optimization when using CONFIG_CC_OPTIMIZE_FOR_SIZE.

Please let me know if I did something wrong or if there are any
objections.

Cheers,
Nathan
