This reverts commit 11d09f2fe7c006b78f7319e876e4ced43f0c1a60. Reason for revert: Failing roll of Tint to Dawn: https://dawn-review.googlesource.com/c/dawn/+/70100 Original change's description: > HLSL: force FXC to never unroll loops > > Emit the "[loop]" attribute on "for" and "while" so that FXC does not > attempt to unroll them. This is to work around an FXC bug where it fails > to unroll loops with gradient operations. > > FXC ostensibly unrolls such loops because gradient operations require > uniform control flow, and loops that have varying iterations may > possibly not be uniform. Tint will eventually validate that control flow > is indeed uniform, so forcing FXC to avoid unrolling in these cases > should be fine. > > Bug: tint:1112 > Change-Id: I10077f8b62fbbb230a0003f3864c75a8fe0e1d18 > Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/69880 > Kokoro: Kokoro <noreply+kokoro@google.com> > Reviewed-by: Ben Clayton <bclayton@google.com> > Commit-Queue: Antonio Maiorano <amaiorano@google.com> # Not skipping CQ checks because original CL landed > 1 day ago.
