Subject: [AMDGPU] Switch to the new cl option amdgpu-atomic-optimizer-strategy.
X-Git-Tag: upstream/17.0.6~4231
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=597fb7fb4640a85c7e144c1ee2b2d0d5e1da4c84;p=platform%2Fupstream%2Fllvm.git

[AMDGPU] Switch to the new cl option amdgpu-atomic-optimizer-strategy.

Atomic optimizer is turned on by default through D152649. This patch
removes the usage of old command line option amdgpu-atomic-optimizations
and transfer the responsibility to `amdgpu-atomic-optimizer-strategy`.

We can safely remove old option when LLPC remove its all usage.
