Immutable access qualifier for pointers and use `__ldg` on cuda. (#8710)

2025-10-16T03:59:47+00:00

This PR implements `Access.Immutable` to allow pointers to immutable data. The new type `ImmutablePtr` is defined as an alias of `Ptr`. By forming a immutable pointer, the programmer is conveying to the compiler that the data at the pointer address will never change during the execution of the current program. Therefore loads from immutable pointers can be deduplicated by the compiler, and will translate to `__ldg` when generating code for CUDA. The SPIRV backend is not changed in this PR, since the current SPIRV spec makes it very difficult to specify loads from immutable address without generating tons of wrappers and boilerplate type declarations. We would like to see the spec evolved a bit to around its support of `NonWritable` physical storage pointers or immutable loads before we attempt to express such immutability in SPIRV. For now we simply emit ordinary pointers and loads when generating spirv. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

[CUDA] Fix incorrect `kIROp_RaytracingAccelerationStructureType` emitting logic (#8168)

2025-08-15T15:24:06+00:00

Fixes: #8167 Current emitting logic does not work, this has been corrected. The provided test ensures our CUDA code is valid by compiling PTX from it. `m_writer->emit("OptixTraversableHandle");` should be `out <<` since `out` adds to type-name-cache; otherwise using a type twice will produce bad type-names (since we filled type-name cache with "" instead of "typeName")
