Newer binutils (>= 2.31) will emit PLT32 relocs for call/jmp
|
|
instructions on x86_64 in some cases, instead of PC32 relocs
|
|
as before. This can only be done because on x86-64 the PLT
|
|
doesn't need any special setup, and in turn this means that
|
|
for post-processing/after-link purposes PLT32 and PC32 relocs
|
|
can be handled the same. elf2efi simply ignores all PC-relative
|
|
relocs (as the code is already fully final for them) and PLT32
|
|
is one of them, so add it to the list.
|
|
|
|
(Otherwise an "Unrecognized relocation type 4" error occurs
|
|
when building some of the EFI images for IPXE).
