From: pvanhout Date: Thu, 6 Apr 2023 12:07:41 +0000 (+0200) Subject: [AMDGPU] Hide "removing function" diagnostics by default X-Git-Tag: upstream/17.0.6~12085 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ff02cf015d3e6bdf80e971355faf5e6b98bd9e9;p=platform%2Fupstream%2Fllvm.git [AMDGPU] Hide "removing function" diagnostics by default Use an `OptimizationRemark` for them even though it's not really an optimization. It just integrates better with the other diagnostics (enabling is easy with `-pass-remark`).
