Revert "Vulkan: Avoid content restore by detecting no-op stencil"
This reverts commit 243d0f899e443cd931c78aba7489382dff79edbb.
Revert "Vulkan: Restore at the end of RP if write-after-invalidate"
This reverts commit e5d52ac3b9a00656acdd912ee8cd62dd14784075.
Revert "Vulkan: Invalidate/restore depth/stencil separately."
This reverts commit 61fa0878964a796f6d3b3c13bc3a3849403ecdbd.
Revert "Vulkan: Move content-defined tracking to ImageHelper"
This reverts commit 2392e6b34c0ddfbfd7b4c3cb67323ba463e11a57.
Causes crashes in Fuchsia x64 and on ARM.
Original CL message:
Content-defined tracking was done in render targets prior to this
change. This had multiple drawbacks:
- When a framebuffer attachment is changed (including the first time
it's set), it's unknown whether the contents of the attachment is
defined.
- Invalidate takes effect at the end of render pass, at which point the
render target objects may be gone. Attachment ImageHelpers are
however correctly tracked.
This change moves content-defined tracking to the ImageHelper itself,
and tracks it per subresource. ImageHelper::onWrite() now receives the
subresource that is being written, and marks it as having defined
content.
A future optimization can make use of this change to
ImageHelper::onWrite to track "dirty" subresources. This can lead to
the removal of unnecessary barriers when same-kind writes are done on
different subresources of the image. See http://anglebug.com/3347#c15
