| 26 | # DATA_PLT - .plt should be in data segment, not text segment. |
| 27 | # BSS_PLT - .plt should be in bss segment |
| 28 | # TEXT_DYNAMIC - .dynamic in text segment, not data segment. |
| 29 | # EMBEDDED - whether this is for an embedded system. |
| 30 | # SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set |
| 31 | # start address of shared library. |
| 32 | # INPUT_FILES - INPUT command of files to always include |
| 33 | # WRITABLE_RODATA - if set, the .rodata section should be writable |
| 34 | # INIT_START, INIT_END - statements just before and just after |
| 35 | # combination of .init sections. |

| 41 | # When adding sections, do note that the names of some sections are used |
| 42 | # when specifying the start address of the next. |
| 43 | # |
| 44 | |
| 45 | # Many sections come in three flavours. There is the 'real' section, |
| 46 | # like ".data". Then there are the per-procedure or per-variable |
| 47 | # sections, generated by -ffunction-sections and -fdata-sections in GCC, |
| 48 | # and useful for --gc-sections, which for a variable "foo" might be |
| 49 | # ".data.foo". Then there are the linkonce sections, for which the linker |
| 50 | # eliminates duplicates, which are named like ".gnu.linkonce.d.foo". |
| 51 | # The exact correspondences are: |
| 52 | # |
| 53 | # Section Linkonce section |
| 54 | # .text .gnu.linkonce.t.foo |
| 55 | # .rodata .gnu.linkonce.r.foo |
| 56 | # .data .gnu.linkonce.d.foo |
| 57 | # .bss .gnu.linkonce.b.foo |
| 58 | # .sdata .gnu.linkonce.s.foo |
| 59 | # .sbss .gnu.linkonce.sb.foo |

| 62 | # .debug_info .gnu.linkonce.wi.foo |
| 63 | # .tdata .gnu.linkonce.td.foo |
| 64 | # .tbss .gnu.linkonce.tb.foo |
