Bug ID: 33702
Summary: GLIBC_ABI_GNU_TLS produced for i386 binaries that do
not need it
Product: binutils
Version: 2.45
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Target: i386
A GLIBC_ABI_GNU_TLS symbol version requirement is supposed to be created only
if the binary uses global-dynamic TLS. It is created for 32-bit executables
that use no TLS at all. (In executables, TLS sequences should be relaxed to
local-exec, that's another reason why there shouldn't be a GLIBC_ABI_GNU_TLS
symbol requirement.)
