2017-11-01PR22374 testcase, function pointer references in .dataAlan Modra1-0/+11
Function pointer references in .data ought to use a dynamic reloc. There shouldn't be any need for a PLT entry and definitely no copy reloc. This test fails on quite a few targets, but isn't something that anyone should worry about too much. It's really just a missed optimization.

2017-10-24[BFD][PR21703]Override the new defined symbol with the old normal symbol ↵Renlin Li1-0/+12
when --allow-multiple-definition is provided. The behavior of _bfd_elf_merge_symbol and _bfd_generic_link_add_one_symbol is inconsistent. In multiple definition case, _bfd_elf_merge_symbol decided to override the old symbol definition with the new defintion, (size, type, target data) In _bfd_generic_link_add_one_symbol, it simply return without doing anything because of allow-multiple-definition is provided. This leaves the symbol in a wrong state. Here, following the documentation, I made this patch to force the old definition override the new definition if the old symbol is not dynamic or weak. Because, in those two cases, it's expected to do some merge. I have checked that, those two cases are properly handled. bfd/ PR ld/21703 * elflink.c (_bfd_elf_merge_symbol): Handle multiple definition case. ld/ PR ld/21703 * testsuite/ld-elf/elf.exp: Run new tests. * testsuite/ld-elf/pr21703-1.s: New. * testsuite/ld-elf/pr21703-2.s: New. * testsuite/ld-elf/pr21703-3.s: New. * testsuite/ld-elf/pr21703-4.s: New. * testsuite/ld-elf/pr21703-r.sd: New. * testsuite/ld-elf/pr21703-shared.sd: New. * testsuite/ld-elf/pr21703.sd: New. * testsuite/ld-elf/pr21703.ver: New.
2017-08-07Support different ld --hash-style in the ld testsuiteAlan Modra1-1/+1
When ld is running with something other than --hash-style=sysv by default, numerous tests need tweaking. Most of the changes just add --hash-style=sysv.

2017-01-02Run more ld tests when not nativeAlan Modra1-18/+26
Many of the ld tests are not run for cross builds, in some cases because the test needs to run a newly linked executable, and in others simply because it was easier to write the test for native only. Even when a test needs to run, it's good to compile and link to exercise the linker. So that's what this patch does. I've also rid us of the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's much simpler to just link with $CC. This does mean that a cross build with cross-compiler installed but no cross C-library will give lots of failures. If that turns out to be too annoying, I guess we can write a tcl procedure to detect it and not run all the extra tests. * Makefile.am (bootstrap): Delete rule.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra1-0/+14
Variables defined in shared libraries are copied into an executable's .bss section when code in the executable is non-PIC and thus would require dynamic text relocations to access the variable directly in the shared library. Recent x86 toolchains also copy variables into the executable to gain a small speed improvement. The problem is that if the variable was originally read-only, the copy in .bss is writable, potentially opening a security hole. This patch cures that problem by putting the copy in a section that becomes read-only after ld.so relocation, provided -z relro is in force. The patch also fixes a microblaze linker segfault on attempting to use dynamic bss variables. bfd/ PR ld/20995 * elf-bfd.h (struct elf_link_hash_table): Add sdynrelro and sreldynrelro.

2015-09-04ld: Extend options for altering orphan handling behaviour.Andrew Burgess1-12/+0
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.
