Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2021-06-02T23:58:25+00:00 2021-06-02T23:58:25+00:00 Yong He yonghe@outlook.com 2021-06-02T23:58:25+00:00 urn:sha1:e67af5b1a3993529c702ff2924dea11fd1017d2e * Various Fixes to gfx, reflection and emit. - Fix GLSL emit to properly output `*bitsTo*` functions for `IRBitCast` insts. - Add line directive mode setting for `ISession`. - Extend `TypeLayout::getElementStride` to handle `VectorType` case. - Fix `IDevice::readBufferResource` 's D3D12 implementation to copy only the requested bytes out. - Fix `render-test` to use the `ISession` from `gfx` instead of creating its own `ISession` to make sure `gfx` and `render-test` agree on WitnessTable and RTTI IDs. - Extend `render-test` to support filling vector and matrix values in the new `set x = ...` TEST_INPUT syntax. - Add a `dynamic-dispatch-15` test case to make sure packing / unpacking works correctly across all targets, and to make sure render-test's RTTI/WitnessTable ID filling logic is correct for non-trivial cases. * Remove default-major test * Fix cyclic reference in `ExtendedTypeLayout`. * Move `lineDirectiveMode` setting to `TargetDesc`. Add `structureSize` to `TargetDesc` and `SessionDesc` for future binary compatibility. * Cleanup.
