Tom Tromey	88b91969e1	Remove per-language op_name functions enum exp_opcode is created from all the .def files, but then each language is required to implement its own op_name function to turn an enum value to a string. This seemed over-complicated to me, and this patch removes the per-language functions in favor of simply using the .def names for all languages. Note that op_name is only used for dumping expressions, which is a maintainer/debug feature.

Andrew Burgess	3df8c6afdd	gdb: fix potentially uninitialised variable In commit: commit `037d7135de` Date: Mon Nov 16 11:36:56 2020 +0000 gdb: improve command completion for 'print', 'x', and 'display' A potential use of an uninitialised variable was introduced. This is fixed in this commit. Previously when analysing /FMT strings for tab completion we considered two possibilities, either the user has typed '/', or the user has typed '/' followed by an alpha-numeric character, as these are the only valid FMT string characters. This meant that if the user type, for example '/@' and then tried to tab complete gdb would use an uninitialised variable. Currently only the first character after the '/' is checked to see if it is alpha-numeric, so if a user typed '/x@@' then gdb would be happy to treat this as a FMT string. Given the goal of this change was primarily to allow tab completion of symbols later in the command when a /FMT was used then I decided to just make the /FMT skipping less smart. Now any characters after the '/' up to the first white space, will be treated as a FMT string. gdb/ChangeLog: * printcmd.c (skip_over_slash_fmt): Reorder code to ensure in_fmt is always initialized.	6 years ago

Nick Alcock	53651de80f	libctf, include: support foreign-endianness symtabs with CTF The CTF symbol lookup machinery added recently has one deficit: it assumes the symtab is in the machine's native endianness. This is always true when the linker is writing out symtabs (because cross linkers byteswap symbols only after libctf has been called on them), but may be untrue in the cross case when the linker or another tool (objdump, etc) is reading them. Unfortunately the easy way to model this to the caller, as an endianness field in the ctf_sect_t, is precluded because doing so would change the size of the ctf_sect_t, which would be an ABI break. So, instead, allow the endianness of the symtab to be set after open time, by calling one of the two new API functions ctf_symsect_endianness (for ctf_dict_t's) or ctf_arc_symsect_endianness (for entire ctf_archive_t's). libctf calls these functions automatically for objects opened via any of the BFD-aware mechanisms (ctf_bfdopen, ctf_bfdopen_ctfsect, ctf_fdopen, ctf_open, or ctf_arc_open), but the various mechanisms that just take raw ctf_sect_t's will assume the symtab is in native endianness and need a later call to ctf_symsect_endianness to adjust it if needed. (This call is basically free if the endianness is actually native: it only costs anything if the symtab endianness was previously guessed wrong, and there is a symtab, and we are using it directly rather than using symtab indexing.) Obviously, calling ctf_lookup_by_symbol or ctf_symbol_next before the symtab endianness is correctly set will probably give wrong answers -- but you can set it at any time as long as it is before then. include/ChangeLog 2020-11-23 Nick Alcock <nick.alcock@oracle.com> ctf-api.h: Style nit: remove () on function names in comments.

Tom Tromey	cbfa382abb	Remove two unnecessary variables from evaluate_subexp_standard I noticed a couple of spots in evaluate_subexp_standard that looked like: value result; result = something; return result; This patch simplifies these spots to a simple "return". gdb/ChangeLog 2020-11-25 Tom Tromey <tom@tromey.com> eval.c (evaluate_subexp_standard): Remove unnecessary variables.	6 years ago
Tom Tromey	af30c400ea	Do not include parser-defs.h from c-lang.h While working on another series, I noticed that c-lang.h does not need to include parser-defs.h. This patch makes this change, and fixes up the two .c files that needed this include. Tested by rebuilding. gdb/ChangeLog 2020-11-25 Tom Tromey <tom@tromey.com> * d-lang.c: Include parser-defs.h. * rust-lang.c: Include parser-defs.h. * c-lang.h: Do not include parser-defs.h.	6 years ago
Alan Modra	21401fc7bf	Duplicate output sections in scripts Previously, ld merged duplicate output sections if such existed in scripts, except for those with a constraint of SPECIAL. This makes scripts with duplicate output section statements create duplicate output sections in the linker output file. * ldlang.c (lang_output_section_statement_lookup): Change "create" parameter to a tristate, if 2 then always create a new output section statement. Update all callers, with lang_enter_output_section_statement using "2". (map_input_to_output_sections): Don't ignore SPECIAL constraint here. * ldlang.h (lang_output_section_statement_type): Update prototype. (lang_output_section_find): Update.	6 years ago

Tankut Baris Aktemur	50757f95a8	gdb/testsuite: do not hard-code location indices in condbreak-multi-context.exp Breakpoint locations are sorted according to their addresses. The addresses are determined by how the compiler emits the code. Therefore, we may have a different order of locations depending on the compiler we use. To make the gdb.base/condbreak-multi-context.exp test flexible enough for different compilers' output, do not hard-code location indices. Tested with GCC and Clang. gdb/testsuite/ChangeLog: 2020-11-24 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.base/condbreak-multi-context.exp: Do not hard-code location indices.	6 years ago

Joel Brobecker	4afa9fd9b0	Add TYPE_CODE_FIXED_POINT handling in print_type_scalar This commit enhances print_type_scalar to include support for TYPE_CODE_FIXED_POINT. This way, any language falling back to this function for printing the description of some types also gets basic ptype support for fixed point types as well. This fixes a couple of XFAILs in gdb.dwarf2/dw2-fixed-point.exp. gdb/ChangeLog: * typeprint.c (print_type_scalar): Add handling of TYPE_CODE_FIXED_POINT. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-fixed-point.exp: Fix the expected output of the "ptype pck__fp1_range_var" test for the module-2 and pascal languages.

Joel Brobecker	e6fcee3a73	Make function fixed_point_scaling_factor a method of struct type This logically connects this function to the object it inspects. gdb/ChangeLog: * gdbtypes.h (struct type) <fixed_point_scaling_factor>: New method, replacing fixed_point_scaling_factor. All callers updated throughout this project. (fixed_point_scaling_factor): Delete declaration. * gdbtypes.c (type::fixed_point_scaling_factor): Replaces fixed_point_scaling_factor. Adjust implementation accordingly.	6 years ago
Joel Brobecker	d19937a74c	Make fixed_point_type_base_type a method of struct type As suggested by Simon, to logically connect this function to the object it inspects. Note that, logically, this method should be "const". Unfortunately, the implementation iterates on struct type objects starting with "this", and thus trying to declare the method "const" triggers a compilation error. gdb/ChangeLog: * gdbtypes.h (struct type) <fixed_point_type_base_type> New method, replacing the fixed_point_type_base_type function. All callers updated throughout this project. (fixed_point_type_base_type): Remove declaration. * gdbtypes.c (type::fixed_point_type_base_type): Replaces fixed_point_type_base_type. Adjust implementation accordingly.	6 years ago
