2018-02-05binutils/testsuite: Support stderr options with `run_dump_test'Maciej W. Rozycki3-43/+157
Add support for the `error', `error_output', `warning' and `warning_output' options for `run_dump_test' input files, based on the version of the procedure in ld/testsuite/lib/ld-lib.exp and providing compatible semantics. These options apply to PROG under test and let test cases specify output expected on stderr as well as express a requirement for PROG to exit unsuccessfully. Messages to match against can be supplied either inline or fetched from a named file. Update procedure description in the introductory comment accordingly. As the exit status from `remote_exec' is regrettably lost in our default implementation of `binutils_run', which is user-overridable, avoid changing this procedure's API and use a global `binutils_run_status' variable to pass the status up to the caller, similarly to how `binutils_run_failed' is handled. Document the new variable in the respective introductory comments. binutils/ * testsuite/config/default.exp (binutils_run): Document `binutils_run_status'. * testsuite/lib/utils-lib.exp (default_binutils_run): Likewise, and set it.

I am checking in the attached patch which updates the binutils support for version 3 binary annotation notes. (Version 3 adds an end address to the ranges covered by the notes, so that it is possible to detect gaps in the coverage).

This is a followup to "binutils nm testsuite tidy". Since the perror in binutils_assemble has been removed, we need to take more care in failure paths.

2017-12-08Fix stripping relocs in a file with mergeable notes.Nick Clifton3-8/+29
A recent Fedora bug (1520805) exposed a problem with objcopy's reloc copying code, when a binary also contains mergeable notes. The note merging code would delete some relocs, but then the reloc copying code would try to put them back again, which did not work. So I am checking in the patch below to fix the problem. The patch also tweaks one of the binutils note merging tests so that it is skipped for the Sparc64 target, since this has funky relocs. binutils * objcopy.c (copy_relocations_in_section): Use the orelocations field of the input section, if it has been initialised. * testsuite/binutils-all/note-2-64.d: Skip test on Sparc64. bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.

2017-11-24elf: Properly compute offsets of note descriptor and next noteH.J. Lu2-2/+13
According to gABI, in a note entry, the note name field, not note name size, is padded for the note descriptor. And the note descriptor field, not note descriptor size, is padded for the next note entry. Also notes are aligned to 4 bytes in 32-bit objects and 8 bytes in 64-bit objects. Since on Linux, .note.ABI-tag and .note.gnu.build-id notes are always aligned to 4 bytes, we need to use alignment of note section or note segment, instead of assuming alignment based on ELF file class.
