Another long-standing regression present in the compiler (dating back to the Tree-SSA merge): the compiler generates code that has an unexpectedly large stack usage for nested calls on strings, because the gimplifier creates temporaries in the outermost scope that have overlapping live ranges.Tested on x86_64-suse-linux, applied on the mainline. 2016-02-29 Eric Botcazou <ebotca...@adacore.com> * gcc-interface/trans.c (finalize_nrv_r): Remove obsolete code. (build_return_expr): Likewise. (Call_to_gnu): If this is a function call and there is no target, create a temporary for the return value for all aggregate types, but never create it for a return statement. Push a binding level around the call in more cases.
