Bug ID: 28311
Summary: `weak_undef_test` failing with gcc versions newer than
5.4.0 (Ubuntu 16.04)
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: saldivarcher at gmail dot com
CC: ian at airs dot com
Target Milestone: ---
As stated in bug 22755, tests are failing in newer gcc versions, I haven't been
able to find the exact version where the change in gcc happened.
GCC 5.3.0:
# weak_undef_test.s
movl $no_such_symbol_, %eax
# weak_undef_test.o
f: b8 00 00 00 00 mov $0x0,%eax
10: R_X86_64_32 no_such_symbol_
# weak_undef_test
4006e5: b8 00 00 00 00 mov $0x0,%eax
GCC 9.3.0:
# weak_undef_test.s
movq no_such_symbol_@GOTPCREL(%rip), %rax
# weak_undef_test.o
f: 48 8b 05 00 00 00 00 mov 0x0(%rip),%rax
12: R_X86_64_REX_GOTPCRELX no_such_symbol_-0x4
# weak_undef_test
7e8: 48 8b 05 f1 17 00 00 mov 0x17f1(%rip),%rax # 1fe0
<no_such_symbol_>
So I'm assuming that the way weak symbols resolve have changed, and the test
should probably be changed to reflect that.
