    • Add cross-platform Workarounds to Context. · 4e5f1451
      Kenneth Russell authored 
      These are distinct from the renderer-level workarounds.

Add the first workaround, loseContextOnOutOfMemory. This is enabled
when the application enables reset notifications via KHR_robustness,
and is intended for more robust handling of errors in key APIs for
Chromium's correctness (in particular, sync objects).

Change Context::getResetStatus to persistently return the "lost" status
if it was set by calling Context::markContextLost. Previously, if
markContextLost was called but the implementation hadn't actually
received an error like a lost device, the "lost" reset status would be
dropped. Returning it only once to the caller is also fragile. Tested
this by manually injecting a failure in FenceSync11::clientWait and
ensuring that Chromium detected it as expected.

    • Fix integer math overflows in the preprocessor · 7f9a55f7
      Olli Etuaho authored 
      Evaluating integer expressions in the ESSL preprocessor may result in
overflowing the signed integer range. Implement wrapping overflow for
preprocessor expressions in a way that doesn't hit any undefined
behavior.  In the ESSL spec, preprocessor expressions are defined to
have mostly the same semantics as in C++. Since C++ doesn't define
what happens on signed integer overflow, we choose to make most of the
operators wrap on overflow for backward compatibility and consistency
with the rest of the ESSL spec.

We reuse the existing wrapping overflow helpers that are
used for constant folding. To be able to do this, the type used in the
preprocessor expression parser is changed from 64-bit to 32-bit.

Shifting negative numbers is implemented as a logical shift. This
cannot be disallowed since dEQP requires shaders shifting negative
numbers to pass compilation.

Undefined bitwise shifts where the offset is greater than 31 will now
result in a compile-time error.

A couple of test cases are now covered by the preprocessor tests
rather than full compilation tests. This isolates the tests better and
they run faster.

      Our for-loop logic was confused so that some unreferenced
