25/* Many sections come in three flavours. There is the 'real' section,
26 like ".data". Then there are the per-procedure or per-variable
27 sections, generated by -ffunction-sections and -fdata-sections in GCC,
28 and useful for --gc-sections, which for a variable "foo" might be
29 ".data.foo". Then there are the linkonce sections, for which the linker
30 eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
