The master branch has been updated by Cary Coutant :

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=158600eb989bcbc364c6d18259f1cb32ea9dc478

commit 158600eb989bcbc364c6d18259f1cb32ea9dc478
Author: Cary Coutant 
Date:   Wed Feb 15 00:25:29 2017 -0800

Disallow --incremental with -pie and force -no-pie for incremental tests.

This is a partial fix for the gold testsuite failures documented in
PR 21090. The use of -fpie triggers some mov-to-lea optimizations that
are not compatible with incremental linking, so those optimizations need
to be disabled. We also diagnose the attempt to use -pie with incremental
linking, and force -no-pie for the incremental tests in case the build has
been configured to have GCC pass -pie all the time.

We still have a problem where compiling with -fpie results in some GOT
entries even when linking with -no-pie. This combination still causes test
failures because we are not updating the GOT entries in an incremental
update
link.

The ld failures seem to be all fixed in 2.29.1. 

However I do as well see several occurrences of the gold error, 
gcctestdir/ld: internal error in relocate, at

checklog v2.29 (master) pie

There seems to be two different tracks going on in this bug thread.

When using gcc compiled with --enable-default-pie, there's still a failure in
the gold linker testsuite in the master branch as of today (commit
ca49a96781f723d43ec49471cbbb50aa511d063e).

`echo g++ -W -Wall-Wstack-usage=262144 -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -fmerge-constants -march=x86-64 -mtune=generic -O2 -pipe

-e 's/-Wp,-D_FORTIFY_SOURCE=[0-9][0-9]*//'` -Wl,--incremental-update
-Wl,-z,norelro -Bgcctestdir/ two_file_test_tmp_2.o two_file_test_1b_ndebug.o
two_file_test_2_ndebug.o two_file_test_main_ndebug.o

gcctestdir/ld: internal error in relocate, at
../../binutils-gdb/gold/x86_64.cc:4300


Second, there's also 18 unexpected failures in the ld testsuite:

--- Comment #22 from Robert West  ---
Thanks for the patches although I didn't saw difference in checklog after
applying them to 2.28.0. I tested both Nick's and H.J. Lu versions. Is it only
applicable to current master or it's just a minor fix? Am I missing something?

I think the main problem is still what Cary Coutant said:
> Similar problem, but this time with incremental linking. If we've already
> done the mov-to-lea conversion during the initial link, an incremental
> update will not be able to apply the correct relocation.
>
>I'm working on a fix. I'm headed out of town, though, so it'll be a few days.

I tried contact him to ask if he's still interested in fixing this be I didn't
get answer. Anyway thank you for helping with this.

My previous checklogs were contaminated by my custom environment. These are as
clean as I can get

Hi Robert,

  Well given that the failures you report in the description are due to an
internal error in the gold linker, I am resetting the component for this PR.

  I have also uploaded an extracted version of one of the failing gold tests
that reproduces the internal error in gold.  I hope that this will allow the
gold maintainers to track down the bug.

Cheers
  Nick
