binutils/binutils-revert-plt32-in-branches.diff
Michael Matz a121495e23 Accepting request 822679 from home:marxin:branches:devel:gcc 
- Update to binutils 2.35:
  * The asseembler can now produce DWARF-5 format line number tables.
  * Readelf now has a "lint" mode to enable extra checks of the files it is processing.
  * Readelf will now display "[...]" when it has to truncate a symbol name.  
    The old behaviour - of displaying as many characters as possible, up to
    the 80 column limit - can be restored by the use of the --silent-truncation
    option.
  * The linker can now produce a dependency file listing the inputs that it
    has processed, much like the -M -MP option supported by the compiler.
- Regenerate add-ulp-section.diff with -p1 due to a fuzzing issue.
- Remove binutils-2.34-branch.diff.gz.
- Regenerate binutils-build-as-needed.diff due to a fuzzing issue.
- Regenerate binutils-fix-invalid-op-errata.diff as one hunk was upstreamed.
- Remove upstreamed patch binutils-pr25593.diff.
- Regenerate unit-at-a-time.patch due to a fuzzing issue.
- Regenerate binutils-revert-plt32-in-branches.diff.

Raw Blame History

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.

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
