68# Many sections come in three flavours. There is the 'real' section,
69# like ".data". Then there are the per-procedure or per-variable
70# sections, generated by -ffunction-sections and -fdata-sections in GCC,
71# and useful for --gc-sections, which for a variable "foo" might be
72# ".data.foo". Then there are the linkonce sections, for which the linker
73# eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
74# The exact correspondences are:
75#
76# Section Linkonce section
77# .text .gnu.linkonce.t.foo
78# .rodata .gnu.linkonce.r.foo
79# .data .gnu.linkonce.d.foo
80# .bss .gnu.linkonce.b.foo
81# .sdata .gnu.linkonce.s.foo
82# .sbss .gnu.linkonce.sb.foo
83# .sdata2 .gnu.linkonce.s2.foo
