2017-01-03Fix PRU GAS for 32-bit hostsDimitar Dimitrov2-7/+18
The PRU GAS port I originally submitted does not build on 32bit hosts. This patch fixes it by aligning md_number_to_chars's definition with the global declaration in tc.h. Here is the original bug report I got: https://github.com/rcn-ee/repos/pull/23#issuecomment-269915175 * config/tc-pru.c (md_number_to_chars): Fix parameter to be valueT, as declared in tc.h.

2017-01-02Run more ld tests when not nativeAlan Modra74-954/+596
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.

2016-12-29Return 'int' rather than 'unsigned short' in avrdis_opcodeYao Qi2-6/+23
avrdis_opcode return type is unsigned short, but -1 at the end of this function is returned. Additionally, print_insn_avr doesn't handle when -1 (in case of memory error) is returned from avrdis_opcode. This patch changes avrdis_opcode returning int indicating the error, and adds a new argument for instruction we got on success. The opcode is 16-bit, so I change local variables type to uint16_t, and include "bfd_stdint.h" as a result. On memory error, print_insn_avr returns -1, which is a common convention among most of print_insn_$ARCH functions. opcodes: 2016-12-29 Yao Qi <yao.qi@linaro.org> * avr-dis.c: Include "bfd_stdint.h" (avrdis_opcode): Change return type to int, add argument insn.

2016-12-29link_hash_copy_indirect and symbol flagsAlan Modra11-47/+63
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among other things, modified _bfd_elf_link_hash_copy_indirect to not copy ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt and pointer_equality_needed when setting up an indirect non-versioned symbol pointing to a non-default versioned symbol. I didn't notice at the time, but the pr18720 testcase fails on hppa-linux with "internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933 in elf32_hppa_relocate_section". Now hppa-linux creates entries in the plt even for local functions, if they are referenced using plabel (function pointer) relocations. So needs_plt is set for foo when processing pr18720a.o. When the aliases in pr28720b.o are processed, we get an indirection from foo to foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol that is used after that point, no plt entry is made for foo and we bomb when relocating the plabel. As shown by the hppa-linux scenario, needs_plt should be copied even for non-default versioned symbols. I believe all of the others ought to be copied too, with the exception of ref_dynamic. Not copying ref_dynamic is right because if a shared lib references "foo" it should not be satisfied by any non-default version "foo@FOO". * elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit copying one flag, ref_dynamic, when versioned_hidden. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise. * elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Use same logic for copying weakdef flags.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra38-186/+609
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.
