Bug ID: 23825
Summary: Linker creates COPY relocs for reference to TLS
symbols
Product: binutils
Version: 2.31
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: [email protected]
CC: wilson at gcc dot gnu.org
Target Milestone: ---
Target: riscv64-*-*
When linking elf/tst-tls12 from glibc the linker creates COPY relocs for the
references to the TLS symbols a1 and a2, ending up overwriting the
.preinit_array and .init_array contents.
$ objdump -t tst-tls12.o | grep 'a[12]'
0000000000000000 *UND* 0000000000000000 a1
0000000000000000 *UND* 0000000000000000 a2
$ objdump -R tst-tls12 | grep COPY
0000000000013d68 R_RISCV_COPY a1
0000000000013d78 R_RISCV_COPY a2
$ objdump -p tst-tls12 | grep INIT
PREINIT_ARRAY 0x0000000000013d68
PREINIT_ARRAYSZ 0x0000000000000008
INIT_ARRAY 0x0000000000013d70
INIT_ARRAYSZ 0x0000000000000008
