# 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
