This reverts the following patch series, as they cause some regresssions. commit 37c1ab67a35025d37d42c449deab5f254f9f59da type: add c99 variable length array support gdb/ * dwarf2loc.c (dwarf2_locexpr_baton_eval): New function. (dwarf2_evaluate_property): New function. * dwarf2loc.h (dwarf2_evaluate_property): New function prototype. * dwarf2read.c (attr_to_dynamic_prop): New function. (read_subrange_type): Use attr_to_dynamic_prop to read high bound attribute. * gdbtypes.c: Include dwarf2loc.h. (is_dynamic_type): New function. (resolve_dynamic_type): New function. (resolve_dynamic_bounds): New function. (get_type_length): New function. (check_typedef): Use get_type_length to compute type length. * gdbtypes.h (TYPE_HIGH_BOUND_KIND): New macro. (TYPE_LOW_BOUND_KIND): New macro. (is_dynamic_type): New function prototype. * value.c (value_from_contents_and_address): Call resolve_dynamic_type to resolve dynamic properties of the type. Update comment. * valops.c (get_value_at, value_at, value_at_lazy): Update comment. commit 26cb189f8b46dbe7b2d485525329a8919005ca8a vla: enable sizeof operator to work with variable length arrays gdb/ * eval.c (evaluate_subexp_for_sizeof) : If the type passed to sizeof is dynamic evaluate the argument to compute the length. commit 04b19544ef6a97b62b2cc4a3170b900e046ab185 vla: enable sizeof operator for indirection gdb/ * eval.c (evaluate_subexp_for_sizeof) : Create an indirect value and retrieve the dynamic type size. commit bcd629a44fff61527430f353cf77e20fe3afc395 vla: update type from newly created value gdb/ * ada-lang.c (ada_value_primitive_packed_val): Re-fetch type from value. (ada_template_to_fixed_record_type_1): Likewise. (ada_to_fixed_type_1): Likewise. * cp-valprint.c (cp_print_value_fields_rtti): Likewise. (cp_print_value): Likewise. * d-valprint.c (dynamic_array_type): Likewise. * eval.c (evaluate_subexp_with_coercion): Likewise. * findvar.c (address_of_variable): Likewise. * jv-valprint.c (java_value_print): Likewise. * valops.c (value_ind): Likewise. * value.c (coerce_ref): Likewise. commit b86138fb0484f42db6cb83abed1e3d0ad2ec4eac vla: print "variable length" for unresolved dynamic bounds gdb/ * c-typeprint.c (c_type_print_varspec_suffix): Added check for not yet resolved high bound. If unresolved, print "variable length" string to the console instead of random length. commit e1969afbd454c09c3aad1990305715f70bc47c3c vla: support for DW_AT_count gdb/ * dwarf2read.c (read_subrange_type): Convert DW_AT_count to a dynamic property and store it as the high bound and flag the range accordingly. * gdbtypes.c (resolve_dynamic_bounds): If range is flagged as RANGE_UPPER_BOUND_IS_COUNT assign low + high - 1 as the new high bound. * gdbtypes.h (enum range_flags): New enum. (struct range_bounds): Add flags member. commit 92b09522dc5a93ba4bda3c1c0b3c58264e357c8a vla: resolve dynamic bounds if value contents is a constant byte-sequence gdb/ * findvar.c (default_read_var_value): Resolve dynamic bounds if location points to a constant blob. commit 3bce82377f683870cc89925ff43aefb7dcce4a77 vla: evaluate operand of sizeof if its type is a vla gdb/ * eval.c (evaluate_subexp_for_sizeof): Add enum noside argument. (evaluate_subexp_standard): Pass noside argument. (evaluate_subexp_for_sizeof) : Handle subscript case if noside equals EVAL_NORMAL. If the subscript yields a vla type re-evaluate subscript operation with EVAL_NORMAL to enable sideffects. * gdbtypes.c (resolve_dynamic_bounds): Mark bound as evaluated. * gdbtypes.h (enum range_flags): Add RANGE_EVALUATED case. gdb/testsuite * gdb.base/vla-sideeffect.c: New file. * gdb.base/vla-sideeffect.exp: New file. commit 504f34326e5ae7c78ebfcdd6ed03c7403b42048b test: cover subranges with present DW_AT_count attribute gdb/testsuite/ * gdb.dwarf2/count.exp: New file. commit 1a237e0ee53bbdee97d72d794b5b42e774cc81c0 test: multi-dimensional c99 vla. gdb/testsuite/ * gdb.base/vla-multi.c: New file. * gdb.base/vla-multi.exp: New file. commit 024e13b46f9c33d151ae82fd9d64c53092fd9313 test: evaluate pointers to C99 vla correctly. gdb/testsuite/ * gdb.base/vla-ptr.c: New file. * gdb.base/vla-ptr.exp: New file. commit c8655f75e2f0fada311be193e3090087a77ec802 test: basic c99 vla tests for C primitives gdb/testsuite/ * gdb.base/vla-datatypes.c: New file. * gdb.base/vla-datatypes.exp: New file. commit 58a84dcf29b735ee776536b4c51ba90b51612b71 test: add mi vla test gdb/testsuite/ * gdb.mi/mi-vla-c99.exp: New file. * gdb.mi/vla.c: New file. --- gdb/d-valprint.c | 1 - 1 file changed, 1 deletion(-) (limited to 'gdb/d-valprint.c') diff --git a/gdb/d-valprint.c b/gdb/d-valprint.c index 755f180..90095cd 100644 --- a/gdb/d-valprint.c +++ b/gdb/d-valprint.c @@ -59,7 +59,6 @@ dynamic_array_type (struct type *type, const gdb_byte *valaddr, true_type = lookup_array_range_type (true_type, 0, length - 1); ival = value_at (true_type, addr); - true_type = value_type (ival); d_val_print (true_type, value_contents_for_printing (ival), -- cgit v1.1
