2074 | help |
2075 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |
2076 | format as it's one that allows arbitrary 64-bit constructs. For | |
2077 | kernels that are loaded within the KSEG compatibility segments the | |
2078 | 32-bit ELF format can optionally be used resulting in a somewhat | |
2079 | smaller binary, but this option is not explicitly supported by the | |
2080 | toolchain and since binutils 2.14 it does not even work at all. | |
