Reflection
Because of using a different compilation toolchain, CUDAnative.jl offers counterpart functions to the code_ functionality from Base:
Missing docstring for CUDAnative.code_llvm. Check Documenter's build log for details.
Missing docstring for CUDAnative.code_ptx. Check Documenter's build log for details.
CUDAnative.code_sass — Functioncode_sass([io], f, types, cap::VersionNumber)Prints the SASS code generated for the method matching the given generic function and type signature to io which defaults to stdout.
The following keyword arguments are supported:
capwhich device to generate code forkernel: treat the function as an entry-point kernelverbose: enable verbose mode, which displays code generation statistics

Convenience macros
For ease of use, CUDAnative.jl also implements @device_code_ macros wrapping the above reflection functionality. These macros evaluate the expression argument, while tracing compilation and finally printing or returning the code for every invoked CUDA kernel. Do note that this evaluation can have side effects, as opposed to similarly-named @code_ macros in Base which are free of side effects.
CUDAnative.@device_code_lowered — Macro@device_code_lowered exEvaluates the expression ex and returns the result of InteractiveUtils.code_lowered for every compiled GPU kernel.
See also: InteractiveUtils.@code_lowered
CUDAnative.@device_code_typed — Macro@device_code_typed exEvaluates the expression ex and returns the result of InteractiveUtils.code_typed for every compiled GPU kernel.
See also: InteractiveUtils.@code_typed
CUDAnative.@device_code_warntype — Macro@device_code_warntype [io::IO=stdout] exEvaluates the expression ex and prints the result of InteractiveUtils.code_warntype to io for every compiled GPU kernel.
See also: InteractiveUtils.@code_warntype
CUDAnative.@device_code_llvm — Macro@device_code_llvm [io::IO=stdout, ...] exEvaluates the expression ex and prints the result of InteractiveUtils.codellvm to io for every compiled GPU kernel. For other supported keywords, see [`GPUCompiler.codellvm`](@ref).
See also: InteractiveUtils.@code_llvm
CUDAnative.@device_code_ptx — Macro@device_code_native [io::IO=stdout, ...] exEvaluates the expression ex and prints the result of GPUCompiler.code_native to io for every compiled GPU kernel. For other supported keywords, see GPUCompiler.code_native.
CUDAnative.@device_code_sass — Macro@device_code_sass [io::IO=stdout, ...] exEvaluates the expression ex and prints the result of CUDAnative.code_sass to io for every compiled CUDA kernel. For other supported keywords, see CUDAnative.code_sass.
CUDAnative.@device_code — Macro@device_code dir::AbstractString=... [...] exEvaluates the expression ex and dumps all intermediate forms of code to the directory dir.
Version and related queries
CUDAnative.version — Functionversion()Returns the version of the CUDA toolkit in use.
version(k::HostKernel)Queries the PTX and SM versions a kernel was compiled for. Returns a named tuple.
CUDAnative.maxthreads — Functionmaxthreads(k::HostKernel)Queries the maximum amount of threads a kernel can use in a single block.
CUDAnative.registers — Functionregisters(k::HostKernel)Queries the register usage of a kernel.
CUDAnative.memory — Functionmemory(k::HostKernel)Queries the local, shared and constant memory usage of a compiled kernel in bytes. Returns a named tuple.
