Output readonly for suitable glsl buffers (#845)

2019-02-13T19:49:02+00:00

* Output readonly on buffers for glsl if resource is readonly. Didn't add to emitGLSLParameterGroup because the cases there seem to to either be implicitly read only, or allow write. * * Improve comments around use of 'readonly' on glsl output * Use readonly with shaderRecord * Add comment pointing out shader record can be rw on vk, so might require changes in the future.

Fix for byte-address buffers on Vulkan (#760)

2018-12-18T14:57:18+00:00

* Fix output comparison for compute tests There was some vestigial logic there that was first doing a string-based comparison of actual/expected output, and then falling back to a path that parsed the expected output as a float, then converted that to an integer, then printed that integer in hex, and did the comparison with the result of that conversion. I'm not even clear on what that code was trying to accomplish, but its main effect was allowing a test failure to slide by unnoticed becaues somehow an all-zeroes actual output file was matching an expected output file with no zeros. My understanding is that it went something like this: * The first line of expected output was `A` (as in hexidecimal for the decimal integer `10`), and the first line of actual output was `0`. * The `StringToFloat` function was failing on the input string `"A"` and returned `0.0` to indicate failure (rather than reporting any kind of error) * We then converted the `0.0` to integer `0` and converted it to a base-16 string `"0"` * The comparison to the actual output passed, and then a careless early exit in the comparison loop meant that a full test would pass as soon as one line of output passed according to this "second change" logic. This change removes the broken code in the test runner since nothing was relying on it, other than the one broken test case we wanted to fix anyway. * Fix the declarations of byte-address buffer methods for Vulkan The HLSL `ByteAddressBuffer` and `RWByteAddressBuffer` types have methods `Load` and `Store` that take *byte* offsets from the start of the buffer, but we translate them into GLSL that uses `uint[]` array, so that indexing into that array will be off by a factor of four. Somehow the code for mutable byte address buffers was written to add 4, 8, and 12 bytes to the base offset of a vector to get to its subsequent components, but I never thought about the implications this would have for the base address itself. This change includes the following fixes: * Any place in the translation of a byte-address `Load` or `Store` method that was using the address/offset value has been changed to use `$1 / 4` instead of `$1`. * The offsets of 4, 8, and 12 have been changed to 1, 2, and 3 since they are now being added to an *index* instead of a byte offset * The `GetDimensions` methods have introduced a factor of `* 4` to account for the fact that they need to return a byte size and not a count of elements. With this change the existing `byte-address-buffer` test now produces the desired output under Vulkan.
