6a010cf67a [GOLD] PowerPC relocation signed overflow check
Relocations with right shifts were calculating wrong overflow status.
Since the addr34 split-field reloc is implemented as an 18-bit high
part with value shifted right by 16 and a 16-bit low part, most of the
pc-relative relocs were affected.

	* powerpc.cc (Powerpc_relocate_functions::rela, rela_ua): Perform
	signed right shift for signed overflow check.

220f99066d [GOLD] PowerPC notoc eh_frame
When generating notoc call and branch stubs without the benefit of
pc-relative insns, the stubs need to use LR to access the run time PC.
All LR changes must be described in .eh_frame if we're to support
unwinding through asynchronous exceptions.  That's what this patch
does.

The patch has gone through way too many iterations.  At first I
attempted to add multiple FDEs, one for each stub.  That ran into
difficulties with do_plt_fde_location which is only capable of setting
the address of a single FDE per Output_data section, and with removing
any FDEs added on a previous do_relax pass.  Removing FDEs (git commit
be897fb774) went overboard in matching the FDE contents.  That means
either stashing the contents created for add_eh_frame_for_plt to use
when calling remove_eh_frame_for_plt, or recreating contents on the
fly (*) just to remove FDEs.  In fact, FDE content matching is quite
unnecesary.  FDEs added by a previous do_relax pass are those with
u_.from_linker.post_map set.  So they can easily be recognised just by
looking at that flag.  This patch keeps that part of the multiple FDE
changes.

In the end I went for just one FDE per stub group to describe the call
stubs.  That's reasonably efficient for the common case of only
needing to describe the __tls_get_addr_opt call stub.  We don't expect
to be making many calls using notoc stubs without pc-relative insns.

*) Which has it's own set of problems.  The contents must be recreated
using the old stub layout, but .eh_frame size can affect stub
requirements so you need to temporarily keep the old .eh_frame size
when creating new stubs, then reset .eh_frame size before adding new
FDEs.

	* ehframe.cc (Fde::operator==): Delete.
	(Cie::remove_fde): Delete.
	(Eh_frame::remove_ehframe_for_plt): Delete fde_data and fde_length
	parameters.  Remove all post-map plt FDEs.

a529dcc854 [GOLD] Tweak keep_text_section_prefix test for PowerPC64 ELFv1
This test checks code layout by function symbol ordering, but that
doesn't work on powerpc64 ELFv1 where the function symbol is on a
descriptor.  A simple work-around is to have nm emit synthetic symbols
marking the code entry point of functions.  Since the text segment is
laid out before the data segment, the synthetic symbols will have
lower addresses than function descriptor symbols and be seen first in
nm -n output.

On other targets, nm --synthetic typically emits symbols on plt
entries.  Since the testcase doesn't call any of the functions of
interest there shouldn't be plt entries for those functions, so there
should be no potentially confusing extra symbols.

5acaada745 Make gold testsuite work with CC and CXX specifying -B
The patch allows the gold testsuite to pass when using something like
the following configure line, which works for the rest of the binutils
testsuite.  At least, it does if you don't configure your gcc with any
of the options that force a particular path to as or ld.

gccdir="/home/alan/build/gcc/prev-"
gccsrc="/home/alan/src/gcc.git"
gcctarg="x86_64-linux"
CC="${gccdir}gcc/xgcc -B${gccdir}gcc/" \
CXX="${gccdir}gcc/xg++ -B${gccdir}gcc/ -I${gccdir}$gcctarg/libstdc++-v3/include -I${gccdir}$gcctarg/libstdc++-v3/include/$gcctarg -I${gccsrc}/libstdc++-v3/libsupc++ -L${gccdir}$gcctarg/libstdc++-v3/src/.libs/" \
~/src/binutils-gdb/configure ...

gold's -Bgcctestdir/ option must come before the -B supplied by $CC
or $CXX, in order to pick up the linker we want to test.  Also when
using a not-yet-installed gcc, it is necessary to provide a collect-ld
in gcctestdir/ as otherwise a collect-ld script in -B${gccdir}gcc/
will be used and the wrong linker tested.

Besides this, the patch fixes some bugs: The $COMPILE -D_FORTIFY_SOURCE
edit was wrong (but worked for usual values), and the $CXXLINK_S edit
unnecessarily but harmlessly used extra backslash quoting.  See
posix shell documentation regarding quoting, or
www.gnu.org/software/bash/manual/bashref.html#Command-Substitution

Also, -Bgcctestdir/ in one place makes it less likely a new test will
be added that accidentally lacks the option.

1074bc6d41 Fix internal error when using --emit-relocs with plugins.
When an .eh_frame section has deferred layout because of plugins, gold
was neglecting to mark the section as deferred. When we later processed
the corresponding relocation section, we were then ignoring it, causing
the internal error later on in the link.

1b115e8e0e Fix problem causing duplicated linker-generated symbols with versions.
When generating _end, _edata, etc. symbols, and a version script provides
a version name, and we are linking against another shared library that
provides those symbols with a different version, gold ends up trying to
resolve the other shared library's symbols to the new definitions, resulting
in two copies of each symbol, one as default, and one as non-default.
This patch tests for that condition, and ignores the symbols provided
by the other shared library.
