This reverts the below commit to not generate PLT32 relocs
|
|
on branches by default. Used for old distros to not have to
|
|
update several packages/tools that can't handle them. I.e.
|
|
a compatibility patch.
|
|
|
|
The patch isn't exactly the reverse of commit bd7ab16b
|
|
because commit 83924b38 later moved the checking code
|
|
around somewhat.
|
|
|
|
The changes in nop-[345].d and pr22842b.S are followups to
|
|
not break the testsuite because of this revert.
|
|
As are the changes to x86-64-branch-2.d and x86-64-branch-3.d.

x86-64: Generate branch with PLT32 relocation
|
|
|
|
Since there is no need to prepare for PLT branch on x86-64, generate
|
|
R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be
|
|
used as a marker for 32-bit PC-relative branches.
|
|
|
|
To compile Linux kernel, this patch:
|
|
|

From: "H.J. Lu" <hjl.tools@gmail.com>

Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32
|
|
|
|
On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared
|
|
objects must use PIC PLT. To use PIC PLT, you need to load
|
|
_GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on
|
|
x86-64 since x86-64 uses PC-relative PLT.
|
|
|
|
On x86-64, for 32-bit PC-relative branches, we can generate PLT32
|
|
relocation, instead of PC32 relocation, which can also be used as
|
|
a marker for 32-bit PC-relative branches. Linker can always reduce
|
|
PLT32 relocation to PC32 if function is defined locally. Local
|
|
functions should use PC32 relocation. As far as Linux kernel is
|
|
concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
|
|
since Linux kernel doesn't use PLT.
|
|
|
|
is needed. It is available on hjl/plt32/master branch at
|
