2010-07-22Fix MSB shift in prelink adjusting debug infocross_prelink_20061201Joseph S dot Myers
This patch fixes an incorrect shift by 58 instead of 56 when computing the most significant byte when prelink adjusts debug info. Please commit if OK. This problem manifests itself as test failures for SPARC64 but not other platforms I've tested, probably because the mmap_base setting for that platform has a nonzero MSB and most others don't. 2009-08-06 Joseph Myers <joseph@codesourcery.com> * src/dwarf2.c (dwarf2_write_le64, dwarf2_write_be64): Shift by 56 not 58 for MSB.

2010-07-22SPARC64 prelink TLS and current kernels supportJoseph S dot Myers
This patch adds TLS support to SPARC64 prelink - largely cut-and-pasted from the 32-bit SPARC support - and updates it to work with kernels postdating the patch 8bcd17411643beb9a601e032d0cf1016909a81d3 "[SPARC64]: Do not allow mapping pages within 4GB of 64-bit VA hole." (March 2006), which changed TASK_UNMAPPED_BASE causing anything prelinked at the old address to segfault on startup. Please commit if OK. 2008-09-29 Joseph Myers <joseph@codesourcery.com> * src/arch-sparc64.c (sparc64_prelink_rela, sparc64_prelink_conflict_rela, sparc64_undo_prelink_rela, sparc64_reloc_class): Handle TLS relocations.

2010-07-22Reuse PT_NULL program headersRichard Sandiford
My original binutils patches for MIPS prelink support were against 2.17, and reserved room for a program header without actually creating one. The mainline (now 2.18) binutils patches ended up adding a PT_NULL header instead. This was needed because of mainline's SIZEOF_HEADER relaxation and was probably a better idea anyway. The patch below therefore teaches the prelinker to remove a PT_NULL header if it needs to find room for a PT_LOAD header. Tested on the MIPS port, where it allows a sysroot built with the mainline binutils to be fully prelinked. Also tested on x86. The patch involves a lot of reidentation, so for reference, I've attached two versions: first the real patch, then the -b form. Richard 200x-xx-xx Richard Sandiford <richard@codesourcery.com> * src/space.c (find_readonly_space): If a new PT_LOAD header is needed, first try removing a PT_NULL header.
