From b08c978f2e18507cbd9853305185665edf05c598 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Thu, 11 Mar 2021 10:09:43 +0100 Subject: [PATCH] tree-optimization/99523 - missing SSA decls in dumps This makes sure to dump SSA names without identifier in the declaration part of a function dump. While we dump the anonymous variable decls the SSA names referencing them appear without a clear reference as to what anonymous variable is used (_3 vs. D.1234). 2021-03-11 Richard Biener PR tree-optimization/99523 * tree-cfg.c (dump_function_to_file): Dump SSA names w/o identifier to the decls section as well, not only those without a VAR_DECL. --- gcc/tree-cfg.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/gcc/tree-cfg.c b/gcc/tree-cfg.c index d04ce212561..7e3aae5f9c2 100644 --- a/gcc/tree-cfg.c +++ b/gcc/tree-cfg.c @@ -8155,7 +8155,12 @@ dump_function_to_file (tree fndecl, FILE *file, dump_flags_t flags) if (gimple_in_ssa_p (cfun)) FOR_EACH_SSA_NAME (ix, name, cfun) { - if (!SSA_NAME_VAR (name)) + if (!SSA_NAME_VAR (name) + /* SSA name with decls without a name still get + dumped as _N, list those explicitely as well even + though we've dumped the decl declaration as D.xxx + above. */ + || !SSA_NAME_IDENTIFIER (name)) { fprintf (file, " "); print_generic_expr (file, TREE_TYPE (name), flags);
