- # 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

- # 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.
