#	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
#		the number of bytes in the beginning of .got.plt which can be
#		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.
#       SYMBOL_ABI_ALIGNMENT - minimum alignment in bytes which needs to be
#               applied to every symbol definition
#       ALL_TEXT_BEFORE_RO - put all code sections before read-only
#               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
#  .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
#  .noinit	.gnu.linkonce.n.foo
#  .persistent	.gnu.linkonce.p.foo
#
#  Each of these can also have corresponding .rel.* and .rela.* sections.

# ------------------------------------------------------------------------
# The multiple forms of conditional shell script syntax that are used in
# this file can be confusing, so here is a quick explanation of how they
# work:
#
# The following all mean "if foo is defined then do/insert <stuff>":
#
#    test -z "$foo" || <stuff> 
#    test -n "$foo" && <stuff>
#    if test -n "$foo"; then <stuff>
#    if [ -n "$foo" ]; then <stuff>
#    ${foo-<stuff>}
#
# Whereas the following all mean "if foo is undefined then do/insert <stuff>":
#
#    test -n "$foo" || <stuff>
#    test -z "$foo" && <stuff>
#    if test -z "$foo"; then <stuff>
#    if [ -z "$foo" ]; then <stuff>
#    ${foo+<stuff>}
#
# If multiple symbols are tested together then they operate as an IOR for
# positive tests and a NOR for negative tests.  ie, the following all do
# <stuff> if either or both of <foo> and <bar> are defined:
#
#    test -z "$foo$bar" || <stuff> 
#    test -n "$foo$bar" && <stuff>
#    if test -n "$foo$bar"; then <stuff>
#
# Whilst the following only do <stuff> if neither <foo> nor <bar> are defined:
#
#    test -n "$foo$bar" || <stuff>
#    if -z "$foo$bar"; then <stuff>
#    test -z "$foo$bar" && <stuff>
#
# Also:
#   foo=${foo-${bar-${baz}}}
# means:
#   If foo is defined, leave it unchanged.  Otherwise if bar is defined
#   then set foo equal to bar, otherwise set foo equal to baz.
