Fix commit 171191bac50e ("Add support for STT_IFUNC"),
, commit
e04d7088afe0 ("PR ld/14088: Always display addend as signed hex
number"),  and

 regressions:

FAIL: VxWorks executable test 1 (dynamic)
FAIL: ld-mips-elf/vxworks-forced-local-1

seen with `mips-vxworks' and `mipsel-vxworks' targets and adjust dump
patterns according to changes made to the presentation of relocation
addends in `readelf -r' and `objdump -r' output.

presentation of relocation addends.

That's a different issue, ld.gold never crashes in mine.

I'm seeing what I think is the same bug; it manifests itself building Swift on
aarch64 (96-core Packet 2A server, with a Cavium ThunderX CPU).

/usr/bin/ld.gold: internal error in relocate_tls, at ../../gold/aarch64.cc:7419

is the error message. Suggestions where to go to help report this more
carefully would be welcomed.

[Bug binutils/21099] New: Strip should update symbol section index after some sections removed?

[jiwang at gcc dot gnu.org]

https://sourceware.org/bugzilla/show_bug.cgi?id=21099

Bug ID: 21099
   Summary: Strip should update symbol section index after some
sections removed?
   Product: binutils
   Version: 2.29 (HEAD)
Status: NEW
  Severity: minor
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: jiwang at gcc dot gnu.org
  Target Milestone: ---

Can be reproduced by two commands:
===

ld --verbose | tac | sed '/^===/d' | sed '/using internal linker script/,$d' |
sed s/*\(.debug_line/_test\ =\ .\;\ *\(.debug_line/ | tac > new.ld

echo "int cal () { return 0; }" > test.c ; gcc -Wl,-T new.ld -g -shared test.c
-o libtest.so ; strip -s libtest.so ; readelf -s libtest.so | grep "_test"

Overall I think that the warning is useful, and it will certainly help prevent
future bugs of this type.  The fixes I have proposed are quite simple, and
there are only four places where the binutils appear to be affected, so the
price seems quite small to me.

Wouldn't it be better to remove this warning from Werror until and unless gcc
can be fixed to not give so many false positives?
