2022-02-06gdb: remove SYMBOL_MATCHES_SEARCH_NAMESimon Marchi3-9/+4
It seems like this macro is not needed at all anymore, it just wraps the function of the same name with the same arguments. Change-Id: I3c342ac8d89c27af5aee1a819dc32cc6396fd41b
2022-02-06gdb: remove SYMTAB_DIRNAME macroSimon Marchi4-13/+19

Add a getter and a setter for a symtab's compunit_symtab. Remove the corresponding macro and adjust all callers. For brevity, I chose the name "compunit" instead of "compunit_symtab" the the field, getter and setter names. Since we are already in symtab context, the _symtab suffix seems redundant.

2022-02-06gdb: remove COMPUNIT_FILETABS macroSimon Marchi7-24/+24
I think that most remaining uses of COMPUNIT_FILETABS intend to get the primary filetab of the compunit_symtab specifically (and not to iterate over all filetabs, for example, those cases would use compunit_filetabs, which has been converted to compunit_symtab::filetabs), so replace mosts uses with compunit_symtab::primary_filetab. In jit.c, function finalize_symtab, we can save the symtab object returned by allocate_symtab and use it, it makes things simpler. Change-Id: I4e51d6d4b40759de8768b61292e5e13c8eae2e38
2022-02-06gdb: move compunit_filetabs to compunit_symtab::filetabsSimon Marchi7-41/+39
Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a method of compunit_symtab. The name filetabs conflicts with the current name of the field. Rename the field to m_filetabs, since at this point nothing outside of compunit_symtab uses it, so we should treat it as private (even though it's not actually private). Rename the last_filetab field to m_last_filetab as well (it's only used on compunit_symtab::add_filetab). Adjust the COMPUNIT_FILETABS macro to keep its current behavior of returning the first filetab. Change-Id: I537b553a44451c52d24b18ee1bfa47e23747cfc3
2022-02-06gdb: add compunit_symtab::set_primary_filetab methodSimon Marchi3-22/+36
Add a method to set the primary filetab of the CU. This is currently done in buildsym_compunit::end_symtab_with_blockvector. Change-Id: I16c51a6b90a4cb4c0c5f183b0f2e12bc64b6fd74
2022-02-06gdb: add compunit_symtab::add_filetab methodSimon Marchi2-10/+15
Add a method to append a filetab/symtab to a compunit_symtab. There is a single place where this is done currently, in allocate_symtab. Change-Id: Ie86c6e34d175728173d1cffdce44acd6cff6c31d
2022-02-06gdb: rename compunit_primary_filetab to compunit_symtab::primary_filetabSimon Marchi7-17/+15
Make compunit_primary_filetab a method of compunit_symtab. Change-Id: Iee3c4f7e36d579bf763c5bba146e5e10d6766768
2022-02-06gdb: remove COMPUNIT_OBJFILE macroSimon Marchi7-14/+13
Remove the macro, update all users to use the getter directly. Change-Id: I3f0fd6f4455d1c4ebd5da73b561eb18a979ef1f6
2022-02-06gdb: add getter/setter for compunit_symtab::objfileSimon Marchi4-8/+18
Rename the field to m_objfile, and add a getter and a setter. Update all users. Change-Id: If7e2f763ee3e70570140d9af9261b1b056253317
2022-02-06Allow non-ASCII characters in Rust identifiersTom Tromey3-18/+129
Rust 1.53 (quite a while ago now) ungated the support for non-ASCII identifiers. This didn't work in gdb. This is PR rust/20166. This patch fixes the problem by allowing non-ASCII characters to be considered as identifier components. It seemed simplest to just pass them through -- doing any extra checking didn't seem worthwhile. The new test also verifies that such characters are allowed in strings and character literals as well. The latter also required a bit of work in the lexer. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=20166
2022-02-06Fix Rust parser bug with function fieldsTom Tromey4-1/+105
In Rust, 'obj.f()' is a method call -- but '(obj.f)()' is a call of a function-valued field 'f' in 'obj'. The Rust parser in gdb currently gets this wrong. This is PR rust/24082. The expression and Rust parser rewrites made this simple to fix -- simply wrapping a parenthesized expression in a new operation handles it. This patch has a slight hack because I didn't want to introduce a new exp_opcode enumeration constant just for this. IMO this doesn't matter, since we should work toward removing dependencies on these opcodes anyway; but let me know what you think of this. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=24082

2022-02-06gdb/doc: update docs for 'info win' and 'winheight' commandsAndrew Burgess1-6/+7
This started by noticing that the docs for 'winheight' are out of date, the docs currently give a specific list of possible window names. However, now that windows can be implemented in Python, it is not possible to list all possible names. I now link the user to a mechanism by which they can discover the valid names for themselves at run time (by using 'info win'). That, and the fact that gdb provides tab-completion of the name at the command line, feels good enough. Finally, I noticed that the docs for 'win info' don't explicitly say that the name of the window is given in the output. This could probably have been inferred, but given I'm now linking to this as a mechanism to find the window name, I'd prefer to mention that the name can be found in the output.
2022-02-06gdb/tui: add window width information to 'info win' outputAndrew Burgess3-1/+68
Now that we support horizontal window placement in the tui, it makes sense to have 'info win' include the width, as well as the height, of the currently visible windows. That's what this commit does. Example output is now: (gdb) info win Name Lines Columns Focus src 12 40 (has focus) asm 12 41 status 1 80 cmd 11 80 I've added a NEWS entry, but the documentation was already suitably vague, it just says that 'info win' displays the size of the visible windows, so I don't think anything needs to be added there. I've also added some tests, as far as I could find, the 'info win' command was previously untested.

2022-02-04sim: Allow toggling of quiet NaN-bit semanticsFaraz Shahbazker5-18/+48
IEEE754-1985 specifies the top bit of the mantissa as an indicator of signalling vs. quiet NaN, but does not define the precise semantics. Most architectures treat this bit as indicating quiet NaN, but legacy (pre-R6) MIPS goes the other way and treats it as signalling NaN. This used to be controlled by a macro that was only defined for MIPS. This patch replaces the macro with a variable to track the current semantics of the NaN bit and allows differentiation between older (pre-R6) and and newer MIPS cores. 2022-02-01 Faraz Shahbazker <fshahbazker@wavecomp.com> sim/common/ChangeLog: * sim-fpu.c (_sim_fpu): New.

2022-02-04ld: Remove emultempl/armcoff.emH.J. Lu1-293/+0
Remove emultempl/armcoff.em which has been unused after commit 2ac93be706418f3b2aebeb22159a328023faed52 Author: Alan Modra <amodra@gmail.com> Date: Mon Apr 16 20:33:36 2018 +0930 Remove arm-aout and arm-coff support This also removes arm-netbsd (not arm-netbsdelf!), arm-openbsd, and arm-riscix. Those targets weren't on the obsolete list but they are all aout, and it doesn't make all that much sense to remove arm-aout without removing them too. * emultempl/armcoff.em: Removed.
2022-02-04gdb: include jit_code_entry::symfile_addr value in names of objfiles created ↵Simon Marchi2-16/+29
by jit reader API This commit includes the JIT object's symfile address in the names of objfiles created by JIT reader API (e.g., << JIT compiled code at 0x7ffd8a0c77a0 >>). This allows one to at least differentiate one from another. The address is the one that the debugged program has put in jit_code_entry::symfile_addr, and that the JIT reader's read function receives. As we can see in gdb.base/jit-reader-host.c and gdb.base/jit-reader.c, that may not be the actual value of where the JIT-ed code is. But it is a value chosen by the author of the JIT engine and the JIT reader, so including this value in the objfile name may help them correlate the JIT objfiles created by with their logs / data structures. To access this field, we need to pass down a reference to the jit_code_entry. So make jit_dbg_reader_data a structure (instead of an alias for a CORE_ADDR) that includes the address of the code entry in the inferior's address space (the previous meaning of jit_dbg_reader_data) plus a reference to the jit_code_entry as read into GDB's address space. And while at it, pass down the gdbarch, so that we don't have to call target_gdbarch. Co-Authored-By: Jan Vrany <jan.vrany@labware.com> Change-Id: Ib26c4d1bd8de503d651aff89ad2e500cb312afa5
2022-02-04Improve Ada unchecked union type printingTom Tromey3-29/+42
Currently, "ptype" of an Ada unchecked union may show a compiler-generated wrapper structure in its output. It's more Ada-like to elide this structure, which is what this patch implements. It turned out to be simplest to reuse a part of print_variant_clauses for this. As this is Ada-specific, and Joel already reviewed it internally, I am going to check it in.
2022-02-04Remove host_hex_valueTom Tromey6-27/+8
I noticed that host_hex_value is redundant, because gdbsupport already has fromhex. This patch removes the former in favor of the latter. Regression tested on x86-64 Fedora 34.
2022-02-03Support symbol+offset lookup in addr2lineAndi Kleen2-13/+80
The Linux kernel usually ouputs symbol+offset instead of plain code addresses these days, to avoid leaking ASLR secrets and to handle dynamically loaded modules. Converting those with addr2line is somewhat involved: it requires looking up the symbol first using nm and then manually compute the offset, and then pass it to addr2line. This patch implements the necessary steps directly in addr2line, by looking up the symbol (with demangling if needed) and computing the offset. It's possible that a symbol is ambigious with a hex number. In this case it uses the symbol lookup if the string contains a +. When it isn't ambigious the + is optional.
