Bug ID: 27491
Summary: ld: relocation R_X86_64_PC32 against undefined
protected symbol `__start_xx' can not be used when
making a shared object
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: i at maskray dot me
Target Milestone: ---
% cat x.s
.weak __start_xx
.weak __stop_xx
.global _start
_start:
movq __start_xx@gotpcrel(%rip), %rdi
movq __stop_xx@gotpcrel(%rip), %rsi
.section xx,"a",unique,0
.byte 0
.section xx,"a",unique,1
.byte 1
% as x.s -o x.o
# With an ld newer than 2021-03-01
% ./ld-new x.o --gc-sections --print-gc-sections -z start-stop-gc -shared
./ld-new: removing unused section 'xx' in file 'x.o'
./ld-new: removing unused section 'xx' in file 'x.o'
./ld-new: x.o: relocation R_X86_64_PC32 against undefined protected symbol
`__start_xx' can not be used when making a shared object
./ld-new: final link failed: bad value
I suspect GOTPCRELX optimization is performed while it shouldn't.
aarch64 ld works without a diagnostic.
