From a7bbb5b1b1eb09db8175130474e8da952f30404b Mon Sep 17 00:00:00 2001 From: Kewen Lin Date: Tue, 18 Aug 2020 21:37:39 -0500 Subject: [PATCH] options: Make --help= see overridden values Options "-Q --help=params" don't show the final values after target option overriding, instead it emits the default values in params.opt (without any explicit param settings). This patch makes it see overridden values. gcc/ChangeLog: * opts-global.c (decode_options): Call target_option_override_hook before it prints for --help=*. --- gcc/opts-global.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/gcc/opts-global.c b/gcc/opts-global.c index b1a8429dc3c..b024ab8e18f 100644 --- a/gcc/opts-global.c +++ b/gcc/opts-global.c @@ -327,8 +327,14 @@ decode_options (struct gcc_options *opts, struct gcc_options *opts_set, unsigned i; const char *arg; - FOR_EACH_VEC_ELT (help_option_arguments, i, arg) - print_help (opts, lang_mask, arg); + if (!help_option_arguments.is_empty ()) + { + /* Make sure --help=* sees the overridden values. */ + target_option_override_hook (); + + FOR_EACH_VEC_ELT (help_option_arguments, i, arg) + print_help (opts, lang_mask, arg); + } } /* Hold command-line options associated with stack limitation. */ -- 2.30.2
