From c0154a4a21a3aed01ef53877af05cf0109a0b124 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 16 Aug 2021 16:17:25 -0700 Subject: gdb: Don't assume r_ldsomap when r_version > 1 on Linux The r_ldsomap field is specific to Solaris (part of librtld_db), and should never be accessed for Linux. glibc is planning to add a field to support multiple namespaces. But there will be no r_ldsomap when r_version is bumped to 2. Add linux_[ilp32|lp64]_fetch_link_map_offsets to set r_ldsomap_offset to -1 and use them for Linux targets.
