| Work around b/189992601: "SSE register cannot be used when SSE is disabled!" |
| |
| The combination of -Xclang -msoft-float and -Xclang -no-implicit-float |
| causes Clang to assert. Since GRUB doesn't use floats, not passing |
| -Xclang -msoft-float is a safe way to avoid this assert. |
| https://bugs.llvm.org/show_bug.cgi?id=48528 tracks fixing this on the |
| LLVM side, after which we won't need this patch anymore. |
