Where do the debug intrinsics come from? As far as I know we just do not copy them over to generated code.

They are generated by Julia when invoked through julia-debug

Right. If I run "opt -polly-codegen-ppcg ~/Downloads/kernel_gemm-before-DEBUG.ll" and remove this line, these is no problem. Is this change really needed. In case it is, please add a test case that breaks without this change. Otherwise, please remove this change.

verifyModule doesn't report errors since the 2nd argument, raw_ostream *OS = nullptr, is left empty. When &(llvm::errs()) is passed as the 2nd argument you get the following output,

DICompileUnit not listed in llvm.dbg.cu
!11 = distinct !DICompileUnit(language: DW_LANG_C89, file: !3, producer: "julia", isOptimized: true, runtimeVersion: 0, emissionKind: FullDebug, enums: !12)

Along with the following which eventually crashes the program.

Cannot invoke an intrinsic other than donothing, patchpoint, statepoint, coro_resume or coro_destroy
  store void (metadata, i64, metadata, metadata)* @llvm.dbg.value, void (metadata, i64, metadata, metadata)** %polly_launch_0_param_7
