In this case address of captured variables should point to the private address space, as function parameters reside in private address space (see "6.5 Address Space Qualifiers" paragraph 3). This makes unclear to me how capturing works for variables declared in the address spaces other than private (e.g. `local int a;`). > The OpenCL spec does not forbid taking address of captured variable. > Forbidding taking address of captured variable would violate the spec. I'm not sure yet, but it might be OpenCL spec inconsistency issue. https://reviews.llvm.org/D36410 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
