| // The memset implementation is verbatim from cortex-strings. |
| // It's a different implementation than the userland memset because vector |
| // registers cannot be used in the kernel. |
| |
| // We include it here so we can define aliases for the sanitizer runtime. The |
| // assembler gives warnings if `.weak foo` and `.global foo` both appear, |
| // though the last one always wins. To avoid touching the cortex-strings code |
| // temporarily redefine `global` as a macro; it's only used once in the file. |
