| # ETEXT_NAME - name of a symbol for the end of the text section, | |
| # normally etext. | |
| # ETEXT_LAST_IN_RODATA_SEGMENT - emit ETEXT_NAME after all sections in | |
| # the read-only data segment (which may or may not be equal to | |
| # the code segment), instead of after just the code parts. | |
| # 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 | |

| # SYMBOL_ABI_ALIGNMENT - minimum alignment in bytes which needs to be | |
| # applied to every symbol definition | |
| # ALL_TEXT_BEFORE_RO - put all code sections before read-only | |
| # sections | |
| # | |
| # 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 | |
| # .noinit .gnu.linkonce.n.foo | |
| # .persistent .gnu.linkonce.p.foo | |
| # | |
| # Each of these can also have corresponding .rel.* and .rela.* sections. | |
