Atomics are not supported on images or texture_buffers in MSL.
Properly throw an error if OpImageTexelPointer is used (since it can
only be used for atomic operations anyways).
* origin/master:
Support running {,update_}test_shader.sh with CMake builds.
Don't apply vertex attribute remapping other non-vertex or non-input interface blocks
Force complex loop in certain rare access chain scenarios.
Fix guard around [[noreturn]].
Deal with mismatched signs in S/U/F conversion opcodes.
Workaround lack of lvalue/rvalue operator overload on MSVC 2013.
Support direct conversions to std::vector from SmallVector.
Fix some minor copy constructor issues in Variant.
Make sure ids_for_types are moved correctly in move operator.
Run format_all.sh.
Refactor out error handling and containers to new headers.
Do not use SmallVector as input type in public interfaces.
Fix various bugs found in testing.
Explicitly implement move operators for ParsedIR.
Try another MSVC 2013 workaround.
Implement edge cases in insert/end and add a simple test case.
Fix GCC 4.x warnings.
Workaround lack of alignas on MSVC 2013.
Reduce pressure on global allocation.
CLI: Make --iterations more useful.
If we generate an access chain in a loop body, and it is consumed in the
loop continue block, we have a problem because we cannot emit a
temporary here holding the access chain reference. Force a complex loop
body to workaround this exceptionally rare case.
- Replace ostringstream with custom implementation.
~30% performance uplift on vector-shuffle-oom test.
Allocations are measurably reduced in Valgrind.
- Replace std::vector with SmallVector.
Classic malloc optimization, small vectors are backed by inline data.
~ 7-8% gain on vector-shuffle-oom on GCC 8 on Linux.
- Use an object pool for IVariant type.
We generally allocate a lot of SPIR* objects. We can amortize these
allocations neatly by pooling them.
- ~15% overall uplift on ./test_shaders.py --iterations 10000 shaders/.
We cannot deduce if OpLoad needs ArrayCopy templates early since it's
heavily context dependent, and we might only know on 3rd iteration of
the compile loop.
We had a bug where error conditions in DoWhileLoop emit path would not
detect that statements were being emitted due to the masking behavior
which happens when force_recompile is true. Fix this.
Also, refactor force_recompile into member functions so we can properly
break on any situation where this is set, without having to rely on
watchpoints in debuggers.
