2 | # Unusual variables checked by this code: | |
3 | # NOP - two byte opcode for no-op (defaults to 0) | |
4 | # DATA_ADDR - if end-of-text-plus-one-page isn't right for data start | |
26c7ca95 | 5 | # INITIAL_READONLY_SECTIONS - at start of text segment |
fa247c00 | 6 | # OTHER_READONLY_SECTIONS - other than .text .init .rodata ... |
267a3ab3 | 7 | # (e.g., .PARISC.milli) |
26c7ca95 | 8 | # OTHER_TEXT_SECTIONS - these get put in .text when relocating |
fa247c00 | 9 | # OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ... |
267a3ab3 | 10 | # (e.g., .PARISC.global) |

20 | # OTHER_BSS_SYMBOLS - symbols that appear at the start of the |
