23 | // We implement a subset of the original GNU ld linker script language |
| 24 | // for compatibility. The goal is not to implement the entire | |
| 25 | // language. It is merely to implement enough to handle common uses. | |
| 26 | // In particular we need to handle /usr/lib/libc.so on a typical | |
| 27 | // GNU/Linux system, and we want to handle linker scripts used by the | |
| 28 | // Linux kernel build. | |
