Message : Reland "Make SH_CLAMP_INDIRECT_ARRAY_BOUNDS do proper AST transformation" This is a reland of a474fd7de769ae817db83490d410510cdbed75b2 The integer clamp used in this transformation is not available in es100 shaders, and float clamp is used instead. Original change's description: > Make SH_CLAMP_INDIRECT_ARRAY_BOUNDS do proper AST transformation > > This translator flag adds a clamp to non-literal indices to arrays. Two > strategies were provisioned, using the clamp intrinsic or a hand-written > function. The latter is ununsed in angle, chromium, firefox and > webkit, so this change removes this option and uses the clamp intrinsic > unconditionally. > > The clamp itself was added at output generation time with special flags > set on the index node. This is changed such that a proper AST > transformation is done and no-special handling would be necessary. > > Bug: angleproject:4361 > Bug: angleproject:4889 > Change-Id: Ieccfd2c1c347563fb5282e9fa66d39304e62f2ca > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2935041 > Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> > Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Bug: angleproject:4361 Bug: angleproject:4889 Change-Id: I9397ec7e6bdfb706c2a891b33fd3b2b79e883ccc Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2940902 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com>
