    • Automate installing the API library for testing · 4c0f888d
      Nicolas Capens authored 
      To run dEQP tests we previously either had to install the Vulkan Loader
and configure it to find the SwiftShader Vulkan ICD, or manually copy
over the library.

This change introduces the SWIFTSHADER_VULKAN_API_LIBRARY_INSTALL_PATH
environment variable, which can be set to a path where the API library
should be copied to. When used with dEQP it ensures we always test with
the last build, instead of the path provided in the JSON file used by
the Vulkan loader.

Note this is only meant as a convenience for SwiftShader development.
It shouldn't be used as a substitute for installing the ICD for
system-wide usage. The latter should probably use CMAKE_INSTALL_PREFIX
instead, but there are no known use cases yet for installing SwiftShader
as the system-level driver, through the CMake build.

    • Fix multiview renderpass queries · a0aeb64e
      Nicolas Capens authored 
      The spec states that "If queries are used while executing a render pass
instance that has multiview enabled, the query uses N consecutive query
indices in the query pool (starting at query) where N is the number of
bits set in the view mask in the subpass the query is used in. How the
numerical results of the query are distributed among the queries is
implementation-dependent. For example, some implementations may write
each view’s results to a distinct query, while other implementations
may write the total result to the first query and write zero to the
other queries."

This wasn't working properly for occlusion queries, but we missed it
because dEQP doesn't provide coverage for this case if timestamp queries
are not supported. This change fixes it for both query types.

Note that for occlusion queries we write the total result to the first
query, and set the remaining query results to 0, as explicitly allowed
by the spec.

For timestamp queries each query result is a valid timestamp (note that
the spec also allows for only the first query to be a timestamp, while
the remaining ones are zero).

    • Implement VK_KHR_timeline_semaphore · 6846389f
      Sean Risser authored 
      Timeline semaphores track a monotonically increasing uint64_t that
serves as a signal to any number of threads on the device or the host.
Threads and the host wait on the value of the payload to become a
specific value, then unblock. Or they can signal the semaphore and
update its value, unblocking all threads waiting on that value in the
process.

Clang's Thread Safety Analysis is not used for TimelineSemaphore as
it has a bug that prevents it from properly analyzing lambdas that access
guarded resources.

    • Simplify If/Else lowering · d85a7a27
      Nicolas Capens authored 
      Previously we would append the 'begin' basic block with the conditional
branch only once we know whether or not there's a 'false' block separate
from the 'end' block (namely when executing the Else statement). We can
instead treat the 'false' block as the 'end' block itself when no Else
is encountered and simply continue emitting instructions in this block.

Note this removes the need to explicitly materialize all variables,
because that's taken care of by createCondBr().
