Subject: [PATCH V2] Update SECTIONS from linker scripts for binutils 2.19 compatibility
|
||||
|
||||
When building the linker script tests on SLES 11, the resulting executable
|
||||
had an invalid size for the interp section. This is dues to a new section
|
||||
that was not present in the old script. This patch adds this section to
|
||||
all of the linker scripts.
|
||||
|
||||
Credit goes to Alan Modra for identifying what change needed to be made

ADAM G. LITKE <agl@us.ibm.com> -
|
||||
Libhugetlbfs ships a set of linker scripts which can be used to enable ELF
|
||||
segment remapping into huge pages. These linker scripts
|
||||
no longer work with the version of binutils shipped with SLES11.
|
||||
|
||||
This has been a known problem. Linker scripts are essentially tied to specific
|
||||
versions of binutils but libhugetlbfs only ships a single
|
||||
set. To avoid maintaining and shipping an ever-growing number of linker
|
||||
scripts, a new method of linking binaries for use with huge
|
||||
pages was developed in libhugetlbfs-2.0. Unfortunately, some customers will
|
||||
likely continue to use the old method of linking
|
||||
binaries (with the shipped linker scripts) and will experience problems. The
|
||||
solution to this problem is either to fix the linker scripts
|
||||
for SLES11 by supplying a distro-specific patch, or strip out the deprecated
|
||||
linker scripts so they cannot be used at all. I would prefer
|
||||
to fix the linker scripts (if possible) to allow customers more time to switch
|
||||
to the new linking method.
|
||||
|
||||
Fix for ppc32 BDT script
|
||||
|
||||
The only linker script that is known to have problems is the script used to
|
||||
place text, data, and bss into huge pages on 32bit
|
||||
PowerPC. The attached patch fixes the issue by adding the 'SPECIAL' notation
|
||||
to the .plt and .got sections which is required for
|
||||
correct functioning of the dynamic linker.
