Bug ID: 34247
Summary: [RISC-V] GNU ld.bfd shared preemptible 32 PCREL wrong
success
Product: binutils
Version: 2.45
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: l784896635 at gmail dot com
Target Milestone: ---
Created attachment 16756

Reduced testcase
I reduced this to the attached RISC-V testcase and can reproduce it 3/3 times.
Observed: GNU ld.bfd 2.45 links the RV32 and RV64 default-visible shared
objects successfully, exports `ext` and `slot` in `.dynsym`, emits no dynamic
relocations, and writes a fixed PC-relative value into `.data` (`ext - slot`)
even though `ext` is preemptible.
Expected: Link RISC-V shared objects containing an `R_RISCV_32_PCREL`
relocation in `.data` against a default-visible function `ext` defined in the
same DSO.
