From 731d2cc1d5106c077584bd83e96dbba4f7e11118 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 5 Aug 2022 08:09:57 +0200 Subject: [gdb] Add debug_{exp,val} When debugging cc1 I heavily rely on simple one-parameter debug functions that allow me to inspect a variable of a common type, like: - debug_generic_expr - debug_gimple_stmt - debug_rtx and I miss similar functions in gdb. Add functions to dump variables of types 'value' and 'expression': - debug_exp, and - debug_val. Tested on x86_64-linux, by breaking on varobj_create, and doing: ... (gdb) call debug_exp (var->root->exp.get ()) &"Operation: OP_VAR_VALUE\n" &" Block symbol:\n" &" Symbol: aaa\n" &" Block: 0x2d064f0\n" (gdb) ... and: ... (gdb) call debug_val (value) &"5" (gdb) ... --- gdb/valprint.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'gdb/valprint.c') diff --git a/gdb/valprint.c b/gdb/valprint.c index f873e12..3ad4c0c 100644 --- a/gdb/valprint.c +++ b/gdb/valprint.c @@ -1190,6 +1190,18 @@ value_print (struct value *val, struct ui_file *stream, current_language->value_print (val, stream, options); } +/* Meant to be used in debug sessions, so don't export it in a header file. */ +extern void ATTRIBUTE_UNUSED debug_val (struct value *val); + +/* Print VAL. */ + +void ATTRIBUTE_UNUSED +debug_val (struct value *val) +{ + value_print (val, gdb_stdlog, &user_print_options); + gdb_flush (gdb_stdlog); +} + static void val_print_type_code_flags (struct type *type, struct value *original_value, int embedded_offset, struct ui_file *stream) -- cgit v1.1
