2# Unusual variables checked by this code:
3# NOP - two byte opcode for no-op (defaults to 0)
4# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
5# INITIAL_READONLY_SECTIONS - at start of text segment
6# OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
7# (e.g., .PARISC.milli)
8# OTHER_TEXT_SECTIONS - these get put in .text when relocating
9# OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
10# (e.g., .PARISC.global)
904ecb2d 11# OTHER_BSS_SECTIONS - other than .bss .sbss ...
252b5132

12# OTHER_SECTIONS - at the end
13# EXECUTABLE_SYMBOLS - symbols that must be defined for an
14# executable (e.g., _DYNAMIC_LINK)
15# TEXT_START_SYMBOLS - symbols that appear at the start of the
16# .text section.
17# DATA_START_SYMBOLS - symbols that appear at the start of the
18# .data section.
19# OTHER_GOT_SYMBOLS - symbols defined just before .got.
20# OTHER_GOT_SECTIONS - sections just after .got and .sdata.
21# OTHER_BSS_SYMBOLS - symbols that appear at the start of the
22# .bss section besides __bss_start.
23# DATA_PLT - .plt should be in data segment, not text segment.
24# TEXT_DYNAMIC - .dynamic in text segment, not data segment.
25# EMBEDDED - whether this is for an embedded system.
26# SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
27# start address of shared library.
28# INPUT_FILES - INPUT command of files to always include
a8e53fb0 29# WRITABLE_RODATA - if set, the .rodata section should be writable
