From f2000085bac1e512f4b9d8598fa0b5a72d600538 Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Sun, 9 Oct 2011 19:43:39 +0000 Subject: gdb/ Display @entry parameter values even for references. * ada-valprint.c (ada_val_print_1) : Try also coerce_ref_if_computed. * c-valprint.c (c_val_print) : Likewise. * dwarf2expr.c (dwarf_block_to_dwarf_reg_deref): New function. (execute_stack_op) : Add -1 deref_size to the existing push_dwarf_reg_entry_value call. Add new detection calling dwarf_block_to_dwarf_reg_deref. Update the error message. (ctx_no_push_dwarf_reg_entry_value): New parameter deref_size. * dwarf2expr.h (struct dwarf_expr_context_funcs) : Add new parameter deref_size, describe it in the comment. (ctx_no_push_dwarf_reg_entry_value): Add new parameter deref_size. (dwarf_block_to_dwarf_reg_deref): New declaration. * dwarf2loc.c (dwarf_entry_parameter_to_value): Add new parameter deref_size, describe it in the function comment. New variables data_src and size, fetch the alternative block accoring to DEREF_SIZE. (dwarf_expr_push_dwarf_reg_entry_value): Add new parameter deref_size, describe it in the function comment. Fetch the alternative block accoring to DEREF_SIZE. (entry_data_value_coerce_ref, entry_data_value_copy_closure) (entry_data_value_free_closure, entry_data_value_funcs): New. (value_of_dwarf_reg_entry): New variables checked_type, target_type, outer_val, target_val, val and addr. Try to fetch and create also referenced value content. (pieced_value_funcs): NULL value for coerce_ref. (needs_dwarf_reg_entry_value): Add new parameter deref_size. * f-valprint.c (f_val_print) : Try also coerce_ref_if_computed. * opencl-lang.c (opencl_value_funcs): NULL value for coerce_ref. * p-valprint.c (pascal_val_print) : Likewise. * stack.c (read_frame_arg): Compare also dereferenced values. * value.c (value_computed_funcs): Make the parameter v const, use value_lval_const for it. (value_lval_const, coerce_ref_if_computed): New function. (coerce_ref): New variable retval. Call also coerce_ref_if_computed. * value.h (struct lval_funcs): New field coerce_ref. (value_computed_funcs): Make the parameter v const. (value_lval_const, coerce_ref_if_computed): New declarations. gdb/testsuite/ Display @entry parameter values even for references. * gdb.arch/amd64-entry-value.cc (reference, datap, datap_input): New functions. (main): New variables regvar, nodatavarp, stackvar1, stackvar2. Call reference and datap_input. * gdb.arch/amd64-entry-value.exp (reference, breakhere_reference): New breakpoints. (continue to breakpoint: entry_reference: reference) (entry_reference: bt at entry) (continue to breakpoint: entry_reference: breakhere_reference) (entry_reference: bt, entry_reference: ptype regparam) (entry_reference: p regparam, entry_reference: ptype regparam@entry) (entry_reference: p regparam@entry, entry_reference: p ®param@entry) (entry_reference: p regcopy, entry_reference: p nodataparam) (entry_reference: p nodataparam@entry): New tests. --- gdb/ada-valprint.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'gdb/ada-valprint.c') diff --git a/gdb/ada-valprint.c b/gdb/ada-valprint.c index 7b9e3ee8707..8a72b9e35c4 100644 --- a/gdb/ada-valprint.c +++ b/gdb/ada-valprint.c @@ -898,9 +898,18 @@ ada_val_print_1 (struct type *type, const gdb_byte *valaddr, if (TYPE_CODE (elttype) != TYPE_CODE_UNDEF) { - CORE_ADDR deref_val_int - = unpack_pointer (type, valaddr + offset_aligned); + CORE_ADDR deref_val_int; + struct value *deref_val; + deref_val = coerce_ref_if_computed (original_value); + if (deref_val) + { + common_val_print (deref_val, stream, recurse + 1, options, + current_language); + break; + } + + deref_val_int = unpack_pointer (type, valaddr + offset_aligned); if (deref_val_int != 0) { struct value *deref_val = -- cgit v1.2.1
