      2 # Unusual variables checked by this code:
      3 #	NOP - four byte opcode for no-op (defaults to 0)
      4 #	NO_SMALL_DATA - no .sbss/.sbss2/.sdata/.sdata2 sections if not
      5 #		empty.
      6 #	DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
      7 #	INITIAL_READONLY_SECTIONS - at start of text segment
      8 #	OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
      9 #		(e.g., .PARISC.milli)
     10 #	OTHER_TEXT_SECTIONS - these get put in .text when relocating
     11 #	OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
     12 #		(e.g., .PARISC.global)
     13 #	OTHER_BSS_SECTIONS - other than .bss .sbss ...
     14 #	OTHER_SECTIONS - at the end
     15 #	EXECUTABLE_SYMBOLS - symbols that must be defined for an
     16 #		executable (e.g., _DYNAMIC_LINK)
     17 #	TEXT_START_SYMBOLS - symbols that appear at the start of the
     18 #		.text section.
     19 #	DATA_START_SYMBOLS - symbols that appear at the start of the
     20 #		.data section.
     21 #	OTHER_GOT_SYMBOLS - symbols defined just before .got.
     22 #	OTHER_GOT_SECTIONS - sections just after .got.
     23 #	OTHER_SDATA_SECTIONS - sections just after .sdata.
     24 #	OTHER_BSS_SYMBOLS - symbols that appear at the start of the
     25 #		.bss section besides __bss_start.
     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.
     36 #	FINI_START, FINI_END - statements just before and just after
     37 #	combination of .fini sections.
     38 #	STACK_ADDR - start of a .stack section.
     39 #	OTHER_END_SYMBOLS - symbols to place right at the end of the script.
     40 #
     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
     60 #  .sdata2	.gnu.linkonce.s2.foo
     61 #  .sbss2	.gnu.linkonce.sb2.foo
     62 #  .debug_info	.gnu.linkonce.wi.foo
     63 #  .tdata	.gnu.linkonce.td.foo
     64 #  .tbss	.gnu.linkonce.tb.foo
