* scripttempl/elf.sc: Add a comment giving the correspondence
between sections, per-datum sections, and linkonce sections. Make the comment true even for .bss, .sdata, .sdata2, .sbss, and .sbss2.

/* 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
|
||||||
|
.data .gnu.linkonce.d.foo
|
||||||
|
.bss .gnu.linkonce.b.foo
|

|

|

|
.sdata2 .gnu.linkonce.s2.foo
|
||||||
|
.sbss2 .gnu.linkonce.sb2.foo
|
||||||
|
|
||||||
|
Each of these can also have corresponding .rel.* and .rela.* sections.
