Remove contrib/binutils, unused after r368667

More ARM EABI object attributes in binutils. This adds support to binutils

2015-04-03T19:33:26Z

to include the Unaligned Access and Floating-point Half-precision attributes. the former marks ELF objects that may access ARMv6 style unaligned data, the latter that the binary uses the VFPv3/Advanced SIMD half-precision extension. These may be emmitted by clang so it's best to print a warning when the linker hits one of them. Differential Revision: http://reviews.freebsd.org/D2194 Submitted by: Michal Meloun MFC after: 1 week

Add new PowerPC relocations to binutils

2014-12-12T03:58:51Z

Summary: LLVM/Clang generates relocations that our binutils doesn't understand, but newer binutils does. I got permission from the author of a series of patches to relicense them as GPLv2 for use in FreeBSD. The upstream git hashes are: ac2df442ac7901f00af15b272fc48b594b433713 2b95367962dc14f69d3c338c4d54195266e2e169 102890f04c44b64cf5cef4588267dd9f24086ac7 b7fcf6f6bb53b5027e111107f5416769cb9a5798 1d483afedd5a628dc84fb58d1d570f79fdfbfa7b 90aecf7a80c1cefeb45fc10a6cd02c8338e34b4c 3a71aa26df2a372a58e9c11ef9ba51fd0e83320a 727fc41e077139570ea8b8ddfd6c546b2a55627c With the import of clang 3.5, and a few backported patches, we should be able to move powerpc and powerpc64 to clang-as-cc soon. Test Plan: Passes make tinderbox, so no regressions. Binaries built with clang run on powerpc64.

Improve support for XSAVE with debuggers.

2014-11-21T20:53:17Z

- Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed to match what Linux does in that 1) it dumps the entire XSAVE area including the fxsave state, and 2) it stashes a copy of the current xsave mask in the unused padding between the fxsave state and the xstate header at the same location used by Linux. - Teach readelf() to recognize NT_X86_XSTATE notes. - Change PT_GET/SETXSTATE to take the entire XSAVE state instead of only the extra portion. This avoids having to always make two ptrace() calls to get or set the full XSAVE state. - Add a PT_GET_XSTATE_INFO which returns the length of the current XSTATE save area (so the size of the buffer needed for PT_GETXSTATE) and the current XSAVE mask (%xcr0).

Add an elf note on ARM to store the MACHINE_ARCH an executable was built

2013-09-26T07:53:18Z

for. This is useful for software needing to know which architecture a binary is built for as arm and armv6 have slight differences meaning only some binaries build for one will work as expected on the other. It is expected pkgng will be able to make use of this to simplify the logic to determine which package ABI to use. Approved by: re (kib)

Improve readelf notes output for Linux ELF files

2013-09-13T18:21:31Z

Add four ELF note constants: - NT_FILE and NT_SIGINFO (core file notes output by recent Linux kernels) - NT_GNU_ABI_TAG (was incorrectly reported as NT_VERSION) - NT_GNU_BUILD_ID (used for locating standalone debug files) Approved by: re (kib)

Handle FreeBSD-specific ELF notes

2013-07-18T17:25:50Z

Add a function to return the specific type, when the note's Name field is 'FreeBSD'. r249558 added FreeBSD-specific ELF note types that reuse type numbers of existing generic / Linux types. This caused 'readelf -n' to produce incorrect output on FreeBSD core files. Sponsored by: DARPA, AFRL MFC after: 3 days

Fix the value of NT_FREEBSD_TAG to be the same as ABI_NOTRTYPE in lib/csu.

Add NT_FREEBSD_NOINIT_TAG for the value of CRT_NOINIT_NOTETYPE. Check for both of these when detecting a FreeBSD binary in gdb.
