Bug ID: 34249
Summary: [RISC-V] bfd RISC-V shared preemptible branch 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 16758

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 for both standard and compressed conditional-branch
relocations, exports `ext` in `.dynsym`, emits no dynamic relocations, and
leaves `caller` with a direct `beq`/`beqz` branch to the local definition.
Expected: Link RISC-V shared objects containing `R_RISCV_BRANCH` and
`R_RISCV_RVC_BRANCH` relocations from `caller` to a default-visible function
`ext` defined in the same DSO.
