Doing it when emitting the initializers seems to be too late to me, we in various spots try to put parts of the static var DECL_INITIAL expressions into the IL, or e.g. for varpool purposes remember which vars are referenced there. This patch moves it to record_reference, which is called from varpool_node::analyze and so about the same time as gimplification of the bodies which also replaces DECL_VALUE_EXPRs. 2023-01-24 Jakub Jelinek <ja...@redhat.com> PR c++/108474 * cgraphbuild.cc: Include gimplify.h. (record_reference): Replace VAR_DECLs with DECL_HAS_VALUE_EXPR_P with their corresponding DECL_VALUE_EXPR expressions after unsharing. * cp-gimplify.cc (cp_fold_r): Revert 2023-01-19 changes. * g++.dg/cpp1z/decomp57.C: New test. * g++.dg/cpp1z/decomp58.C: New test.
