Bug ID: 26236
Summary: ld on sparc produces R_SPARC_NONE relocations
Product: binutils
Version: 2.34
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: slyfox at inbox dot ru
Target Milestone: ---
Target: sparc-unknown-linux-gnu
Initially the problem was observed by Rolf Eike Beer on elfutils as
https://bugs.gentoo.org/619706.
There elutils test suite caught that ld produces R_SPARC_NONE relocations on
PIE executables.
Attaching small archive with 3 object files hopefully enough to reproduce the
problem.
