The build error message:
src/cc/frontends/clang/loader.cc:400:73: error: no matching function for
call to ‘clang::TextDiagnosticPrinter::TextDiagnosticPrinter(
llvm::raw_fd_ostream&, clang::DiagnosticOptions*)’
400 | auto diag_client = new TextDiagnosticPrinter(llvm::errs(), &*diag_opts);
| ^
The llvm commit
llvm/llvm-project#139584
caused the build failure.
Adjust the code properly and the error is fixed.
