# 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 |
|||
