From 8884fc918f6aee220f9b41806974508bd0213aca Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Fri, 5 Apr 2024 12:31:22 -0700 Subject: powerpc: Fix fatal warnings flag for LLVM's integrated assembler When building with LLVM_IAS=1, there is an error because '-fatal-warnings' is not recognized as a valid flag: clang: error: unsupported argument '-fatal-warnings' to option '-Wa,' Use the double hyphen version of the flag, '--fatal-warnings', which works with both the GNU assembler and LLVM's integrated assembler.
