| # Unusual variables checked by this code: |
| # NOP - four byte opcode for no-op (defaults to none) |
| # NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not |
| # empty. |
| # SMALL_DATA_CTOR - .ctors contains small data. |
| # SMALL_DATA_DTOR - .dtors contains small data. |
| # DATA_ADDR - if end-of-text-plus-one-page isn't right for data start |
| # INITIAL_READONLY_SECTIONS - at start of text segment |
| # OTHER_READONLY_SECTIONS - other than .text .init .rodata ... |
| # (e.g., .PARISC.milli) |
| # OTHER_TEXT_SECTIONS - these get put in .text when relocating |
| # INITIAL_READWRITE_SECTIONS - at start of data segment (after relro) |
| # OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ... |
| # (e.g., .PARISC.global) |
| # OTHER_RELRO_SECTIONS - other than .data.rel.ro ... |
| # (e.g. PPC32 .fixup, .got[12]) |
| # OTHER_RELRO_SECTIONS_2 - as above, but after .dynamic in text segment |
| # OTHER_BSS_SECTIONS - other than .bss .sbss ... |
| # ATTRS_SECTIONS - at the end |
| # OTHER_SECTIONS - at the end |
| # EXECUTABLE_SYMBOLS - symbols that must be defined for an |
| # executable (e.g., _DYNAMIC_LINK) |
| # TEXT_START_ADDR - the first byte of the text segment, after any |
| # headers. |
| # TEXT_BASE_ADDRESS - the first byte of the text segment. |
| # TEXT_START_SYMBOLS - symbols that appear at the start of the |
| # .text section. |
| # DATA_START_SYMBOLS - symbols that appear at the start of the |
| # .data section. |
| # DATA_END_SYMBOLS - symbols that appear at the end of the |
| # writeable data sections. |
| # OTHER_GOT_SYMBOLS - symbols defined just before .got. |
| # OTHER_GOT_SECTIONS - sections just after .got. |
| # OTHER_PLT_SECTIONS - sections just after .plt. |
| # OTHER_SDATA_SECTIONS - sections just after .sdata. |
| # OTHER_BSS_SYMBOLS - symbols that appear at the start of the |
| # .bss section besides __bss_start. |
| # PLT_NEXT_DATA - .plt next to data segment when .plt is in text segment. |
| # DATA_PLT - .plt should be in data segment, not text segment. |
| # PLT_BEFORE_GOT - .plt just before .got when .plt is in data segement. |
| # BSS_PLT - .plt should be in bss segment |
| # NO_REL_RELOCS - Don't include .rel.* sections in script |
| # NO_RELA_RELOCS - Don't include .rela.* sections in script |
| # NON_ALLOC_DYN - Place dynamic sections after data segment. |
| # TEXT_DYNAMIC - .dynamic in text segment, not data segment. |
| # EMBEDDED - whether this is for an embedded system. |
| # SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set |
| # start address of shared library. |
| # INPUT_FILES - INPUT command of files to always include |
| # WRITABLE_RODATA - if set, the .rodata section should be writable |
| # INIT_START, INIT_END - statements just before and just after |
| # combination of .init sections. |
| # FINI_START, FINI_END - statements just before and just after |
| # combination of .fini sections. |
| # STACK_ADDR - start of a .stack section. |
| # OTHER_SYMBOLS - symbols to place right at the end of the script. |
| # ETEXT_NAME - name of a symbol for the end of the text section, |
| # normally etext. |
| # SEPARATE_CODE - if set, .text and similar sections containing |
| # actual machine instructions must be in wholly disjoint |
| # pages from any other data, including headers |
| # SEPARATE_GOTPLT - if set, .got.plt should be separate output section, |
| # so that .got can be in the RELRO area. It should be set to |
| # the number of bytes in the beginning of .got.plt which can be |
| # in the RELRO area as well. |
| # USER_LABEL_PREFIX - prefix to add to user-visible symbols. |
| # RODATA_NAME, SDATA_NAME, SBSS_NAME, BSS_NAME - base parts of names |
| # for standard sections, without initial "." or suffixes. |
| # |
| # When adding sections, do note that the names of some sections are used |
| # when specifying the start address of the next. |
| # |
| |
| # Many sections come in three flavours. There is the 'real' section, |
| # like ".data". Then there are the per-procedure or per-variable |
| # sections, generated by -ffunction-sections and -fdata-sections in GCC, |
| # and useful for --gc-sections, which for a variable "foo" might be |
| # ".data.foo". Then there are the linkonce sections, for which the linker |
| # eliminates duplicates, which are named like ".gnu.linkonce.d.foo". |
| # The exact correspondences are: |
| # |
| # Section Linkonce section |
| # .text .gnu.linkonce.t.foo |
| # .rodata .gnu.linkonce.r.foo |
| # .data .gnu.linkonce.d.foo |
| # .bss .gnu.linkonce.b.foo |
| # .sdata .gnu.linkonce.s.foo |
| # .sbss .gnu.linkonce.sb.foo |
| # .sdata2 .gnu.linkonce.s2.foo |
| # .sbss2 .gnu.linkonce.sb2.foo |
| # .debug_info .gnu.linkonce.wi.foo |
| # .tdata .gnu.linkonce.td.foo |
| # .tbss .gnu.linkonce.tb.foo |
| # .lrodata .gnu.linkonce.lr.foo |
| # .ldata .gnu.linkonce.l.foo |
| # .lbss .gnu.linkonce.lb.foo |
| # |
| # Each of these can also have corresponding .rel.* and .rela.* sections. |
