2020-05-03Update more calls to add_prefix_cmdTom Tromey13-173/+86
I looked at all the calls to add_prefix_cmd, and replaced them with calls to add_basic_prefix_cmd or add_show_prefix_cmd when appropriate. This makes gdb's command language a bit more regular. I don't think there's a significant downside. Note that this patch removes a couple of tests. The removed ones are completely redundant. gdb/ChangeLog 2020-05-03 Tom Tromey <tom@tromey.com> * breakpoint.c (catch_command, tcatch_command): Remove.

2020-05-01PR25882, .gnu.attributes are not checked for shared librariesAlan Modra4-4/+20
This allows backend merge_private_bfd_data to examine shared library e_flags and/or .gnu.attributes. ARM and PowerPC have done so when using ld.gold for a long time. (The tic6x change below is dead code due to the earlier FIXME, but this is probably one of the changes needed there.)

2020-05-01FIXME for merging of e_flags and .gnu.attributesAlan Modra11-0/+51
Code in the linker, present before the addition of .gnu.attributes support, results in shared libraries not being considered by BFD when merging e_flags and .gnu.attributes from input files to the output. That doesn't seem correct to me, but I don't know enough about all the various ABIs to change the behaviour with any confidence. So this patch merely punts on dynamic objects in merge_private_bfd_data target functions, with a FIXME for maintainer attention. I haven't excluded shared libraries from being considered where the target merge_private_bfd_data (a) already has code dealing with shared libraries, or (b) where that function just sets the output to the most constraining arch/mach combination and other fairly trivial merges, or (c) when the target has no shared library linker support. In (a) are: arc, arm, aarch64, riscv, sparc. In (b) are: bpf, cris, csky, m32r, m68k, mn10300, nios2, tilegx, tilepro, vax, visium, xtensa. In (c) are: bpf, cr16, h8300, iq2000, m32c, m68hc11, m68hc12, mcore, mep, msp430, mt, rl78, rx, v850.

2020-04-30Calculate size of array of stubbed typeHannes Domani7-0/+126
Sizes of stubbed types are calculated on demand in check_typedef, so the same must also be done for arrays of stubbed types. A stubbed type is usually a structure that has only been forward declared, but can also happen if the structure has a virtual function that's not inline in the class definition. For these stubbed types, the size must be recalculated once the full definition is available. gdb/ChangeLog: 2020-04-30 Hannes Domani <ssbssa@yahoo.de> PR gdb/18706 * gdbtypes.c (check_typedef): Calculate size of array of stubbed type. gdb/testsuite/ChangeLog: 2020-04-30 Hannes Domani <ssbssa@yahoo.de> PR gdb/18706 * gdb.cp/stub-array-size.cc: New test. * gdb.cp/stub-array-size.exp: New file. * gdb.cp/stub-array-size.h: New test. * gdb.cp/stub-array-size2.cc: New test.

2020-04-29gdb: fix shellcheck warnings SC2154 (referenced but not assigned) in gdbarch.shSimon Marchi2-7/+12
Fix all instances of this kind of warning: In gdbarch.sh line 96: m ) staticdefault="${predefault}" ;; ^-----------^ SC2154: predefault is referenced but not assigned. These warnings appear because we are doing something a bit funky when reading the gdbarch fields. These variables are not assigned explicitly, but using some `eval` commands. I don't think there is so much we can fix about those warnings. To silence them, I've changed `${foo}` to `${foo:-}`. This tells the shell to substitute with an empty string if `foo` is not defined. This retains the current behavior, but the warnings go away. gdb/ChangeLog: * gdbarch.sh: Use ${foo:-} where shellcheck would report a "referenced but not assigned" warning.

2020-04-29Fix Ada crash with .debug_typesTom Tromey2-34/+36
PR ada/25875 concerns a gdb crash when gdb.ada/arr_enum_idx_w_gap.exp is run using the .debug_types board. The problem turns out to be caused by weird compiler output. In this test, the compiler emits a top-level type that refers to an enumeration type which is nested in a function. However, this function is just a declaration. This results in gdb calling read_enumeration_type for the enum type, but process_enumeration_scope is never called, yielding an enum with no fields. This causes the crash. This patch fixes the problem by arranging to create the enum fields in read_enumeration_type. Tested on x86-64 Fedora 30. gdb/ChangeLog 2020-04-29 Tom Tromey <tromey@adacore.com> PR ada/25875: * dwarf2/read.c (update_enumeration_type_from_children): Compute type fields here. (read_enumeration_type): Call update_enumeration_type_from_children later. Update comments. (process_enumeration_scope): Don't create type fields.
