2021-04-19gas: drop sprint_value()Jan Beulich7-30/+19
Its (documented) behavior is unhelpful in particular in 64-bit build environments: While printing large 32-bit numbers in decimal already isn't very meaningful to most people, this even more so goes for yet larger 64-bit numbers. bfd_sprintf_vma() still tries to limit the number of digits printed (without depending on a build system property), but uniformly produces hex output.

Rather than hand duplicate the syscall constants, switch to the common nltvals framework. I made sure the constants have the same values before & after too :).

2021-04-18sim: d10v: fix build warningsMike Frysinger4-5/+17
The printf fix uses our PRIxTA for our sim address type. Then cast away the const (since the underlying code safely treats it as such) even if it's ugly. Finally touch up the argv iterator pointer to match the new func arg. With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call to get the default common behavior where -Werror is enabled.
2021-04-18sim: cr16: fix build warningsMike Frysinger4-4/+14
The printf fix is obvious enough, but the hash one is a real bug: cr16/interp.c: In function 'sim_open': cr16/interp.c:560:17: error: 'h' may be used uninitialized in this function [-Werror=maybe-uninitialized] 560 | h = h->next; | ~~^~~~~~~~~ It happens to not cause a problem currently because the first entry in the generated table that this loop operates matches a codepath where h is initialized. Then when later entries don't match, the previous value is pointing at the end of a valid hash table already, and the rest of the code does nothing. With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call to get the default common behavior where -Werror is enabled.

2021-04-17Handle unaligned mapping of .gdb_indexTom Tromey4-81/+132
The .gdb_index was designed such that all data would be aligned. Unfortunately, we neglected to require this alignment in the objcopy instructions in the manual. As a result, in many cases, a .gdb_index in the wild will not be properly aligned by mmap. This yields undefined behavior, which is PR gdb/23743. This patch fixes the bug by always assuming that the mapping is unaligned, and using extract_unsigned_integer when needed. A new helper class is introduced to make this less painful. gdb/ChangeLog 2021-04-17 Tom Tromey <tom@tromey.com> PR gdb/23743: * dwarf2/read.c (class offset_view): New.

2021-04-17Simplify quick_symbol_functions::map_matching_symbolsTom Tromey8-84/+76
quick_symbol_functions::map_matching_symbols is only used by the Ada code. Currently, it both expands certain psymtabs and then walks over the full symtabs -- including any already-expanded ones -- calling a callback. It appears to work lazily as well, in that if the callback returns false, iteration stops. However, only the psymtab implementation does this; the DWARF index implementations are not lazy. It turns out, though, that the only callback that is ever passed here never returns false. This patch simplifies this method by removing the callback. The method is also renamed. In the new scheme, the caller is responsible for walking the full symtabs, which removes some redundancy as well. gdb/ChangeLog 2021-04-17 Tom Tromey <tom@tromey.com> * psymtab.c (psymbol_functions::expand_matching_symbols): Rename from map_matching_symbols.

2021-04-17Add 'domain' parameter to expand_symtabs_matchingTom Tromey11-18/+66
Currently, expand_symtabs_matching only accepts a search_domain parameter. However, lookup_symbol uses a domain_enum instead, and the two, confusingly, do quite different things -- one cannot emulate the other. So, this patch adds a domain_enum parameter to expand_symtabs_matching, with UNDEF_DOMAIN used as a wildcard.

This changes expand_symtabs_exp_notify_ftype to return bool, and updates all the uses. Now, if the notification function returns false, the call is short-circuited and stops examining symtabs.

2021-04-16Rewrite the Rust expression parserTom Tromey7-2890/+2373
The Rust expression parser was written to construct its own AST, then lower this to GDB expressions. I did this primarily because the old expressions were difficult to work with; after rewriting those, I realized I could remove the AST from the Rust parser. After looking at this, I realized it might be simpler to rewrite the parser. This patch reimplements it as a recursive-descent parser. I kept a fair amount of the existing code -- the lexer is pulled in nearly unchanged. There are several benefits to this approach: * The parser is shorter now (from 2882 LOC to 2351). * The parser is just ordinary C++ code that can be debugged in the usual way. * Memory management in the parser is now straightforward, as parsing methods simply return a unique pointer or vector. This required a couple of minor changes to the test suite, as some errors have changed. While this passes the tests, it's possible there are lurking bugs, particularly around error handling. gdb/ChangeLog 2021-04-16 Tom Tromey <tom@tromey.com> * rust-parse.c: New file. * rust-exp.y: Remove. * Makefile.in (COMMON_SFILES): Add rust-parse.c.

2021-04-16gdb/testsuite: use -gdwarf-4 in simavr boardSimon Marchi2-0/+8
By default, when using the -g switch, avr-gcc generates stabs debug information. I think it would make more sense to test GDB against DWARF information, because stabs is obsolete by now, and nobody work on it. So change the simavr board to pass -gdwarf-4 as the debug flag. The downside is that users are probably more likely to use just -g, so we don't test GDB the same way as users are likely to use it. But in this case, if somebody comes and asks for help with GDB for AVR, I suggest we encourage them to use -gdwarf-4. I can't give stats about how that changes test results, because the testsuite is too broken. There is an internal error that happens quite frequently that needs to be investigated: /home/simark/src/wt/avr/gdb/trad-frame.h:143: internal-error: LONGEST trad_frame_saved_reg::addr() const: Assertion `m_kind == trad_frame_saved_reg_kind::ADDR' failed.

Claim that the accumulator indices are out of range without raising an exception if the CPU doesn't support media instructions. sim/frv/ChangeLog: * traps.c (frvbf_check_acc_range): Add missing return value.
2021-04-15sim: Add SIM_EXTRA_CFLAGS after CSEARCH.John Baldwin2-4/+9
The bfin sim adds include paths for the SDL libraries. These include paths might include headers for different version of binutils. Move SIM_EXTRA_CFLAGS after CSEARCH to ensure local includes are always preferred to external includes. sim/common/ChangeLog: * Make-common.in (CONFIG_CFLAGS): Remove SIM_EXTRA_CFLAGS. (ALL_CLAGS, COMMON_DEP_CFLAGS): Add SIM_EXTRA_CFLAGS after CSEARCH.
2021-04-15gdb fbsd-nat: Use new-style debug macrosJohn Baldwin2-35/+28
gdb/ChangeLog: * fbsd-nat.c (fbsd_lwp_debug_printf, fbsd_nat_debug_printf): New, use throughout file.
2021-04-15gdb/testsuite: don't include paths in test namesAndrew Burgess2-1/+7
Give a test a proper name in order to avoid including a path in the test name. gdb/testsuite/ChangeLog: * gdb.python/py-parameter.exp: Give a test a proper name to avoid including a path in the test name.
2021-04-15gdb/testsuite: use foreach_with_prefix in gdb.threads/fork-plus-threads.expSimon Marchi2-6/+8
I noticed that using foreach_with_prefix could make things a bit less verbose. No changes in behavior expected. gdb/testsuite/ChangeLog: * gdb.threads/fork-plus-threads.exp: Use foreach_with_prefix. Change-Id: I06aa6e3d10a9cfb6ada11547aefe8c70b636ac81
2021-04-15Avoid crash in Ada value printing with optimized-out arrayTom Tromey4-2/+45
The Ada value-printing code could crash when printing an array which had been optimized out. The crash is difficult to reproduce, but I did manage to write a test that at least shows that the previous behavior was incorrect -- before the patch, the array is printed as if it is valid and every value is 0. gdb/ChangeLog 2021-04-15 Tom Tromey <tromey@adacore.com> * ada-valprint.c (ada_value_print_array): Handle optimized-out arrays. gdb/testsuite/ChangeLog 2021-04-15 Tom Tromey <tromey@adacore.com> * gdb.dwarf2/arr-stride.exp: Add test.
2021-04-15Use common_val_print_checked in print_variable_and_valueTom Tromey2-1/+6
GDB was crashing in "bt full" for a large Ada program. I tracked this down to a combination of bugs. The first bug, fixed here, is that print_variable_and_value calls common_val_print. Normally only the value-printing implementation should call this; from the top level, common_val_print_checked is preferred, because it correctly handles values that are wholly optimized out. I wasn't able to write a test case for this. gdb/ChangeLog 2021-04-15 Tom Tromey <tromey@adacore.com> * printcmd.c (print_variable_and_value): Use common_val_print_checked.
2021-04-15Use block_symbol in var_value_operationTom Tromey15-70/+122
I noticed that var_value_operation takes a block and a symbol, and most callers destructure a block_symbol to pass in. It seems better for this class to simply hold a block_symbol instead. Tested on x86-64 Fedora 32. gdb/ChangeLog 2021-04-15 Tom Tromey <tromey@adacore.com> * rust-exp.y (rust_parser::convert_ast_to_expression): Update. * parse.c (parser_state::push_symbol, parser_state::push_dollar): Update. * p-exp.y (variable): Update. * m2-exp.y (variable): Update. * go-exp.y (variable): Update. * expprint.c (dump_for_expression): New overload. * expop.h (check_objfile): New overload. (check_constant): New overload. (class var_value_operation): Use block_symbol. <get_symbol>: Rewrite. * eval.c (var_value_operation::evaluate) (var_value_operation::evaluate_funcall) (var_value_operation::evaluate_for_address) (var_value_operation::evaluate_for_address) (var_value_operation::evaluate_with_coercion) (var_value_operation::evaluate_for_sizeof) (var_value_operation::evaluate_for_cast): Update. * d-exp.y (PrimaryExpression): Update. * c-exp.y (variable): Update. * ax-gdb.c (var_value_operation::do_generate_ax): Update. * ada-lang.c (ada_var_value_operation::evaluate_for_cast) (ada_var_value_operation::evaluate) (ada_var_value_operation::resolve) (ada_funcall_operation::resolve): Update. * ada-exp.y (write_var_from_sym, write_object_renaming) (write_ambiguous_var, write_var_or_type, write_name_assoc) (maybe_overload): Update. * ada-exp.h (class ada_var_value_operation) <get_block>: Rewrite.
