AS		 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
