# 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

# .bss .gnu.linkonce.b.foo

# .debug_info .gnu.linkonce.wi.foo
|
||||
# .tdata .gnu.linkonce.td.foo
|

# .tbss .gnu.linkonce.tb.foo
|
