2015-09-24Relative DT_RPATH/DT_RUNPATH vs. sysroot capable ld.Alan Modra3-11/+14
This fixes two problems. First, the --sysroot option wasn't available with a ld configured without --with-sysroot, a historical accident. This led to people configuring binutils with --with-sysroot=/ in order to enable sysroot support, which exposes a case where ld wrongly prepends the sysroot to a relative path. PR ld/18992 * ldmain.c (main): Always enable --sysroot. * emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Don't prepend sysroot to relative rpath/runpath.

2015-09-18Delay converting linker script defined symbols from absoluteAlan Modra13-8/+142

The new orphan handling tests added in commit c005eb9 fail on a range of targets. Some of the failures were fixed in commit e32aa93 but not all. This commit should address the remaining failures.

2015-09-04ld: Extend options for altering orphan handling behaviour.Andrew Burgess18-65/+195
Replace the options --warn-orphan and --no-warn-orphan with a single option --orphan-handling=MODE, where mode can be place, warn, error, and discard. Mode 'place' is the default, and is the current behaviour, placing the orphan section into a suitable output section. Mode 'warn' is the same as '--warn-orphan'. The orphan is also placed using the same algorithm as for 'place'. Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'. Mode 'discard' assigns all output sections to the /DISCARD/ section. ld/ChangeLog: * ld.h (enum orphan_handling_enum): New. (ld_config_type): Remove warn_orphan, add orphan_handling. * ldemul.c (ldemul_place_orphan): Remove warning about orphan sections. * ldlang.c (ldlang_place_orphan): New function.

2015-08-13Issue an error for read-only segment with dynamic IFUNC relocationsH.J. Lu7-0/+48
To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls __mprotect on the read-only segment with PROT_READ|PROT_WRITE before applying dynamic relocation. It leads to segfault when performing IFUNC relocations since the read-only segment has no execute permission. This patch changes x86 linker to issue an error for read-only segment with dynamic IFUNC relocations. Other backends with IFUNC support may need a similar change. bfd/ PR ld/18801 * elf32-i386.c (elf_i386_size_dynamic_sections): Issue an error for read-only segment with dynamic IFUNC relocations. * elf64-x86-64.c (elf_x86_64_size_dynamic_sections): Likewise. ld/testsuite/ PR ld/18801 * ld-i386/i386.exp: Run pr18801. * ld-x86-64/x86-64.exp: Likewise. * ld-i386/pr18801.d: New file. * ld-i386/pr18801.s: Likewise. * ld-x86-64/pr18801.d: Likewise. * ld-x86-64/pr18801.s: Likewise.

2015-08-12[AArch64] Fix test failures on elf configurationJiong Wang6-29/+47
This patch fixed those failures on elf configuration by: * Improve the ILP32 target selector "aarch64_choose_ilp32_emul", makes it more robust. Target triples copied from configure.tgt * Updated emit-relocs-86/-overflow.d to use aarch64_choose_ilp32_emul which is following what have done with emit-relocs-28. * Those instruction encoding mismatch is because those encoding contains pc-relative address. As for elf, we may have different start address. relaxed encodind check, especially for aarch64-farcall-b/bl-plt, as the main purpose of those check are ELF text/data layout, we just want to make sure veneer to plt stub is generated. 2015-08-12 Jiong Wang <jiong.wang@arm.com> ld/testsuite/ * ld-aarch64/aarch64-elf.exp (aarch64_choose_ilp32_emul): Support all four triple shapes: aarch64-*-linux*, aarch64-*-elf, aarch64_be-*-linux*, aarch64_be-*-elf. * ld-aarch64/emit-relocs-86.d: Use aarch64_choose_ilp32_emul. * ld-aarch64/emit-relocs-86-overflow.d: Likewise. * ld-aarch64/ld-aarch64/farcall-b-plt.d: Relax instrucion encoding check when they reflect address. * ld-aarch64/ld-aarch64/farcall-bl-plt.d: Likewise.
