christos 88c1089d96 Bring in 2 patches from binutils: 
From Alan Modra: Wed, 3 Jul 2013 11:51:56 +0930: powerpc64 call stubs:
    This brings powerpc64 ld in line with gold regarding calls allowed to
    go via a plt call stub or toc-adjusting stub without a following nop.
    A long time ago ld allowed tail calls, but this is wrong because we'll
    return to the caller's caller with the wrong toc pointer.  I fixed
    that for shared libraries but allowed tail calls in an executable for
    some reason.  Probably just muddy thinking on my part, because there's
    no difference between an executable and a shared library regarding the
    need to restore the toc pointer.  Perhaps it was because some testcase
    failed, most likely due to the g++ issue I comment on in the patch.

From Alan Modra: 29 Aug 2014 01:22:29 +0000: PowerPC64 call lacks nop error:
    Enough people accidentally or otherwise use -mcmodel=small then wonder
    why a call that is local is behaving as if it is going via the PLT.

	* elf64-ppc.c (ppc64_elf_relocate_section): Report a different
	error for calls via a toc adjusting stub without a nop.

christos f890372b86 - Add -f to allow processing non-plain files. 
- Align NetBSD note printing properly
- Add handling of "PaX" notes correctly. Perhaps we should rename them
  to "NetBSD" now.

the existing support and most imporantly adds support for shared libraries.

skrll 0e4096dbcc Decode alpha st_other 2014-08-11 20:57:28 +00:00
skrll 8e4a73da69 Apply change from upstream to fix PR/48709 - port-alpha/48709: static 
threaded programs crash.

With this fix the new weak symbol's st_other is not merged in, i.e. NOPV
is not copied from the libc __libc_thr_init.

* elflink.c (_bfd_elf_merge_symbol): If merging a new weak
symbol that will be skipped, we don't have a new definition.

matt 547b3a3b01 Changes to existing files to enable building AARCH64 userland. 
evbarm64-el
This is clang only.  While gcc4.8 supports aarch64, no netbsd support has
been written for aarch64 with gcc4.8.

matt 1a3430eb55 Bias the cfi pc expr by nbytes since vax pcrel are relative to end of the 
relocation, not the beginning.  By adding the size of relocation, it will
become relative to the start of the relocation.

nakayama 8813083ebc Enable 64-bit integer handling for gas even on 32-bit host since 
sparc64 kernel now uses 64-bit constant with %hh operator.

Fix for PR toolchain/48630.

something inappropriate.

christos a15708a3bd gcc-4.8 has begun putting code in .text.unlikely etc. This breaks our 
assumption that .text code comes first in kernels about bootblock so
that the first symbol defined becomes the start address. This change
puts .text before other .text like sections.

joerg a07180c32d Recursively add DT_NEEDED entries from shared libraries if symbols are 
used indirectly. This is more in line with the old GNU ld behavior, but
not exactly the desired semantic.

Patch from Martin Husemann.

christos 4c55f68194 Allow bfd_mach_arm4 machines to produce a.out binaries. 
Perhaps we should just let every arm machine produce them?
Or we should use M_ARM6_NETBSD midmag for those?
