From 8d76c007afe4c70f51fd56b0e5b89522de5de61f Mon Sep 17 00:00:00 2001 From: Thomas Koenig Date: Sun, 20 Dec 2020 16:27:01 +0100 Subject: [PATCH] Set DECL_ARTIFICIAL on gfortran internal variables. It seems we sometimes use DECL_ARTIFICIAL as choosing between different code paths. In order not to make -fdebug-aux-vars do different things, set DECL_ARTIFICIAL on the variables to avoid these different code paths (and the corresponding regressions). gcc/fortran/ChangeLog: * trans.c (create_var_debug_raw): Set DECL_ARTIFICIAL on variables. --- gcc/fortran/trans.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/gcc/fortran/trans.c b/gcc/fortran/trans.c index 7ee2bd159fc..09104f35ee7 100644 --- a/gcc/fortran/trans.c +++ b/gcc/fortran/trans.c @@ -97,6 +97,9 @@ create_var_debug_raw (tree type, const char *prefix) t = build_decl (input_location, VAR_DECL, get_identifier (name_buf), type); + /* Not setting this causes some regressions. */ + DECL_ARTIFICIAL (t) = 1; + /* We want debug info for it. */ DECL_IGNORED_P (t) = 0; /* It should not be nameless. */ -- 2.30.2
