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

| 83 | # .bss .gnu.linkonce.b.foo |
| 84 | # .sdata .gnu.linkonce.s.foo |
| 85 | # .sbss .gnu.linkonce.sb.foo |
| 86 | # .sdata2 .gnu.linkonce.s2.foo |
| 87 | # .sbss2 .gnu.linkonce.sb2.foo |
| 88 | # .debug_info .gnu.linkonce.wi.foo |
| 89 | # .tdata .gnu.linkonce.td.foo |
| 90 | # .tbss .gnu.linkonce.tb.foo |
| 91 | # .lrodata .gnu.linkonce.lr.foo |
| 92 | # .ldata .gnu.linkonce.l.foo |
| 93 | # .lbss .gnu.linkonce.lb.foo |
| 94 | # |
| 95 | # plus exception-handling information for Tensilica's XCC compiler: |
| 96 | # .xt_except_table .gnu.linkonce.e.foo |
| 97 | # .xt_except_desc .gnu.linkonce.h.foo |
| 98 | # |
| 99 | # plus Xtensa-specific literal sections: |
| 100 | # .literal .gnu.linkonce.literal.foo |
| 101 | # .lit4 .gnu.linkonce.lit4.foo |
| 102 | # |
| 103 | # plus Xtensa-specific "property table" sections: |

| 105 | # .xt.insn .gnu.linkonce.x.foo (obsolete) |
