Conflicts: trunk/src/arch-x86_64.c
2011-12-21Add support for new X86_64 - x32 ABI.prelink-x32Mark Hatle
Experimental support for x32, based on the existing X86_64 support. While this has been tested, I consider it experimental, like the x32 ABI. See https://sites.google.com/site/x32abi/home for the ABI document. All work based on version 0.6 -- August 13, 2011 Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

2011-12-21Implement PL_ARCH(arch)Mark Hatle
In order to allow for multiple (related) architectures to be defined in the same file, we allow an arch setting for each PL_ARCH string. The code is based on work originally done by Code Sourcery, LLC. (Now part of Mentor Graphics.) Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

2011-09-13Fix printf typecast problemMark Hatle
See http://bugzilla.pokylinux.org/show_bug.cgi?id=1473 Without this fix the printed TLS(...) information is incorrect, which causes the core prelinker code to incorrectly prelink. This bug triggers primarily on x86 (32-bit) hosts, targeting x86 (32-bit) targets and arm targets. 2011-09-13 Mark Hatle <mark.hatle@windriver.com> * Fix printf problem causing prelink-rtld issues on x86 (32-bit) and arm Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2011-09-01Fix merge (gather.c)Mark Hatle
The merge in gather.c was incorrect. Revert to the previous version of the file. The upstream change was not necessary as the "maybe_pie" function is more robust then the revised PIE detection code. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

2011-08-31Check for an invalid GNU_HASH entryMark Hatle
We added an assert to check for an invalid GNU_HASH entry. See Yocto bug #1331. On a PPC64 image the GNU_HASH table become corrupt, causing the prelink-rtld to access invalid memory. We want to detect and avoid this in the future. 2011-08-26 Mark Hatle <mark.hatle@windriver.com> * Add a special check for invalid GNU_HASH entries Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

2010-07-22Fix MIPS debug info prelinkingAndrew Stubbs
Hi all, Prelink currently fails to relocate the debug info in MIPS libraries because they use a custom section type. Here is an example section from PPC: [29] .debug_frame PROGBITS 00000000 0021b0 00002c 00 0 0 4 The type is "PROGBITS", which is what prelink likes, so it works correctly. Now, here is an example from an equivalent MIPS binary: [28] .debug_frame MIPS_DWARF 00000000 000ee8 00002c 00 0 0 4 Here the type is "MIPS_DWARF", a type not handled by prelink. Please accept the attached patch to fix this. Thanks Andrew 2010-05-06 Andrew Stubbs <ams@codesourcery.com> * src/dso.c (adjust_dso): Support MIPS debug sections. * src/prelink.h (SHT_MIPS_DWARF): New define.
