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 | |
