The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

# Unusual variables checked by this code:
|
|
# NOP - four byte opcode for no-op (defaults to 0)
|
|
# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
|
|
# INITIAL_READONLY_SECTIONS - at start of data segment
|
|
# OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
|
|
# (e.g., .PARISC.milli)
|
|
# OTHER_TEXT_SECTIONS - these get put in .text when relocating
|
|
# OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
|
|
# (e.g., .PARISC.global)
|
|
# OTHER_SECTIONS - at the end
|
|
# EXECUTABLE_SYMBOLS - symbols that must be defined for an
|
|
# executable (e.g., _DYNAMIC_LINK)
|
|
# 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.
|
|
# OTHER_GOT_SYMBOLS - symbols defined just before .got.
|
|
# OTHER_GOT_SECTIONS - sections just after .got.
|
|
# OTHER_SDATA_SECTIONS - sections just after .sdata.
|
|
# OTHER_BSS_SYMBOLS - symbols that appear at the start of the
|
|
# .bss section besides __bss_start.
|
|
# DATA_PLT - .plt should be in data segment, not text segment.
|
|
# BSS_PLT - .plt should be in bss 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.
|
|
#
|
|
# 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
|
|
#
|
|
# Each of these can also have corresponding .rel.* and .rela.* sections.
