The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

|
|
# ETEXT_NAME - name of a symbol for the end of the text section,

|
# normally etext.
|
|
# 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

# 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.
