Bug ID: 107419
Summary: attributes are ignored when selecting TLS model
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
+++ This bug was initially created as a clone of Bug #107353 +++
__attribute__((common))
__thread int i;
int *f()
{
return &i;
}
C frontend invokes decl_default_tls_model before processing attributes,
assigning local-exec model as if the 'common' attribute was not present.
Recomputing it later would select initial-exec model, breaking internal
verification that was weakened to solve PR 107353.
