@aaron.ballman Can you please commit this on my behalf? My github username is ffrankies <https://github.com/ffrankies>.

And could you take a look at D72241 altera single work item barrier check <https://reviews.llvm.org/D72241>? It's also been updated and awaiting review.

Comment at: clang-tools-extra/clang-tidy/altera/KernelNameRestrictionCheck.cpp:90

+               "Naming your OpenCL kernel source file 'kernel.cl', 'Verilog.cl'"
+               ", or 'VHDL.cl' could cause compilation errors.");

My bad, I copied this line over the from other diagnostic and didn't change "including" to "compiling". Will update shortly


================
Comment at: clang-tools-extra/test/clang-tidy/checkers/altera-kernel-name-restriction.cpp:40
+// The files can still have the forbidden names in them, so long as they're not the entire file name
+#include "some_kernel.cl"
+#include "other_Verilog.cl"

Yes, this is fine. The guide only specifies potential errors when the kernel source file is named kernel.cl, verilog.cl, or vhdl.cl. 

I've added additional test cases that use these names as directory names below.
