[PATCH] D100492: [OpenCL] Change OpenCL builtin version encoding

Mon Apr 26 10:15:45 PDT 2021

srj added a comment.

This change appears to be the injection point for https://bugs.llvm.org/show_bug.cgi?id=50128 -- trying to build clang-tblgen after this change crashes VC2019 if targeting 32-bit Windows (see below). While this is likely an MSVC bug, I presume we still want to support crosscompiling for 32-bit  Windows?
