Subject: [PATCH 32/46] Make our dummy .reloc sections not depend on section
|
|
order.
|
|
|
|
Currently on x64 we manually build a dummy .reloc table entry by using a
|
|
symbol in .text and subtracting its address from another symbol that's
|
|
inside the .reloc section. On ia32 we just use its location. In either
|
|
case, if the linker puts either section in a location we're not
|
|
expecting, the .reloc table winds up having invalid values, and the PE
|
|
loader will fail to load the binary.
|
|
|
|
This changes it to be two symbols that are both in .text, making the
|
|
result unrelated to the section order or location.
|
|
|
|
It's not clear to me that these .reloc entries are actually necessary at
|
|
all, but I'm going to leave them in place for now, in case they are.
