2020-01-19sim: add some stdlib.h includesSimon Marchi7-2/+21
When trying to compile GDB with --target=avr, with gcc 9.2.0, I am getting a bunch of: /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: error: implicit declaration of function ‘abort’ [-Werror=implicit-function-declaration] 94 | abort (); | ^~~~~ /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: error: incompatible implicit declaration of built-in function ‘abort’ [-Werror] /home/simark/src/binutils-gdb/sim/avr/../common/nrun.c:94:7: note: include ‘<stdlib.h>’ or provide a declaration of ‘abort’ I did what the compiler told me and added the relevant includes in the problematic files. sim/common/ChangeLog: * nrun.c: Include stdlib.h. * sim-core.c: Likewise. * sim-engine.c: Likewise. * sim-io.c: Likewise. * sim-module.c: Likewise. * sim-reason.c: Likewise.

2020-01-19Call disassemble_free_target in gdbTom Tromey3-1/+19
Commit 20135676fc4c3912297c313b3e0d3cbd6cc402e3 ("PR24960, Memory leak from disassembler") added "disassemble_free_target" to opcodes. This is used to free target-specific data when finished with a disassembler. This patch changes gdb to call this function where needed. gdb/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * disasm.c (~gdb_disassembler): New destructor. (gdb_buffered_insn_length): Call disassemble_free_target. * disasm.h (class gdb_disassembler): Declare destructor. Use DISABLE_COPY_AND_ASSIGN. Change-Id: I245ba5b7dec5e5d9f29cd21832c6e2b4fecef047
2020-01-19Replace init_cutu_and_read_dies with a classTom Tromey2-323/+267
init_cutu_and_read_dies takes a callback function, which I've always found somewhat difficult to follow. This patch replaces this function with a class, and changes the callers to use it. In some cases this allows for the removal of a helper struct and helper function as well. gdb/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * dwarf2read.c (abbrev_table_up): Move typedef earlier.

2020-01-19Remove flickering from the TUITom Tromey9-5/+116
In some cases, the TUI flickers when redrawing. This can be seen mostly easily when switching layouts. This patch fixes the problem by exploiting the double buffering that curses already does. In some spots, the TUI will now disable flushing the curses buffers to the screen; and then flush them all at once when the rendering is complete. gdb/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_assembly): Use tui_suppress_output. * tui/tui-wingeneral.h (class tui_suppress_output): New.

2020-01-19Make "file" clear TUI source windowTom Tromey4-5/+22
I noticed that a plain "file" will leave the current source file in the TUI source window. Instead, I think, it should clear the source window. This patch implements this. gdb/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_line): Handle case where symtab is null. gdb/testsuite/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * gdb.tui/main.exp: Add check for plain "file".

2020-01-17Fix gdbsupport build on compilers that don't default to C++11 or abovePedro Alves3-0/+9
gdbsupport fails to build with compilers that don't default to C++11 or above. gdbsupport's configure.ac is already using AX_CXX_COMPILE_STDCXX, which sets CXX_DIALECT to the -std=gnu++11 switch if necessary, but the problem is that nowhere are we using CXX_DIALECT. This fixes it. gdbsupport/ChangeLog: 2020-01-17 Pedro Alves <palves@redhat.com> * Makefile.am: Append CXX_DIALECT to CXX. * Makefile.in: Regenerate.
2020-01-17Fix gdbsupport buildPedro Alves5-54/+62
I'm seeing this on F27 (a clean build from scratch): ~~~~~~~~~~~~~~~~~~~~~~~~~~~ make[3]: Entering directory '/home/pedro/brno/pedro/gdb/binutils-gdb/build/gdbsupport' CC gdb_tilde_expand.o In file included from /home/pedro/gdb/binutils-gdb/src/gdbsupport/../gnulib/import/libc-config.h:33:0, from ../gnulib/import/glob.h:544, from /home/pedro/gdb/binutils-gdb/src/gdbsupport/gdb_tilde_expand.c:22: ../bfd/config.h:7:4: error: #error config.h must be #included before system headers # error config.h must be #included before system headers ^~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~ libc-config.h, where it includes config.h, says: ~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* This is intended to be a good-enough substitute for glibc system macros like those defined in <sys/cdefs.h>, so that Gnulib code shared with glibc can do this as the first #include: #ifndef _LIBC # include <libc-config.h> #endif When compiled as part of glibc this is a no-op; when compiled as part of Gnulib this includes Gnulib's <config.h> and defines macros that glibc library code would normally assume. */ #include <config.h> ~~~~~~~~~~~~~~~~~~~~~~~~~~~ The issue is that that '#include <config.h>' picks up bfd's config.h instead of gnulib's. This problem doesn't trigger in the gdb dir because there we generate config.h under that exact name so gnulib's libc-config.h ends up picking gdb's config.h instead of gnulib.c and that ends up harmless. In gdbsupport, the config.h file is really named support-config.h, so that '#include <config.h>' in libc-config.h doesn't pick it like it would if it had the conventional config.h name. This patch fixes it by simply renaming gdbserver's support-config.h to config.h. gdbsupport/ChangeLog: 2020-01-17 Pedro Alves <palves@redhat.com> * configure.ac: Generate config.h instead of support-config.h. * common-defs.h: Include <gdbsupport/config.h> instead of <gdbsupport/support-config.h>. * Makefile.in: Regenerate. * configure: Regenerate.
2020-01-17x86: Add {vex} pseudo prefixH.J. Lu8-11/+40
There are 2-byte VEX prefix and 3-byte VEX prefix. 2-byte VEX prefix can't encode all operands. By default, assembler tries 2-byte VEX prefix first. {vex3} can be used to force 3-byte VEX prefix.

2020-01-16Add type for $_tlb->process_environment_block->process_parametersHannes Domani2-1/+65
The type then looks like this: (gdb) pt $_tlb->process_environment_block->process_parameters type = struct rtl_user_process_parameters { DWORD32 maximum_length; DWORD32 length; DWORD32 flags; DWORD32 debug_flags; void *console_handle; DWORD32 console_flags; void *standard_input; void *standard_output; void *standard_error; unicode_string current_directory; void *current_directory_handle; unicode_string dll_path; unicode_string image_path_name; unicode_string command_line; void *environment; DWORD32 starting_x; DWORD32 starting_y; DWORD32 count_x; DWORD32 count_y; DWORD32 count_chars_x; DWORD32 count_chars_y; DWORD32 fill_attribute; DWORD32 window_flags; DWORD32 show_window_flags; unicode_string window_title; unicode_string desktop_info; unicode_string shell_info; unicode_string runtime_data; } * It's mainly useful to get the current directory, or the full command line: (gdb) p $_tlb->process_environment_block->process_parameters->current_directory $1 = { length = 26, maximum_length = 520, buffer = 0xe36c8 L"C:\\src\\tests\\" } (gdb) p $_tlb->process_environment_block->process_parameters->command_line $2 = { length = 94, maximum_length = 96, buffer = 0xe32aa L"\"C:\\gdb\\build64\\gdb-git\\gdb\\gdb.exe\" access.exe" } The type names are all lowercase because the existing types created by windows_get_tlb_type are also lowercase.

2020-01-16[binutils][arm] PR25376 Change MVE into a CORE_HIGH featureAndre Vieira6-243/+275
This patch moves MVE feature bits into the CORE_HIGH section. This makes sure .fpu and -mfpu does not reset the bits set by MVE. This is important because .fpu has no option to "set" these same bits and thus, mimic'ing GCC, we choose to define MVE as an architecture extension rather than put it together with other the legacy fpu features. This will enable the following behavior: .arch armv8.1-m.main .arch mve .fpu fpv5-sp-d16 #does not disable mve. vadd.i32 q0, q1, q2 This patch also makes sure MVE is not taken into account during auto-detect. This was already the case, but because we moved the MVE bits to the architecture feature space we must make sure ARM_ANY does not include MVE. gas/ChangeLog: 2020-01-16 Andre Vieira <andre.simoesdiasvieira@arm.com> PR 25376 * config/tc-arm.c (mve_ext, mve_fp_ext): Use CORE_HIGH.

2020-01-16x86: VPEXTRQ/VPINSRQ are unavailable outside of 64-bit modeJan Beulich7-20/+70
The AVX512DQ patterns lacking a Cpu64 attribute made the memory operand forms accepted even outside of 64-bit mode, and this even without any {evex} pseudo-prefix (otherwise one could argue that this is an attempt to follow one possible, albeit somewhat odd, interpretation of the SDM wording to this effect). For consistency between the various involved templates drop the * (now) unnecessary IgnoreSize attributes * unnecessary (due to VexW1) Size64 attributes from VEX encoded forms * redundant (with Reg64) Qword operand attributes uniformly.

2020-01-15texi2pod.pl: import support for @t{...} from gccSimon Marchi2-0/+5
GDB's man page source (in gdb.texinfo) contains: @t{++} The @t{...} part is supposed to display the wrapped text with a fixed-width font. The texi2pod.pl script currently doesn't handle @t{...}, so it appears as-is in the man page: You can use GDB to debug programs written in C, C@t{++}, Fortran and Modula-2. gcc's version of texi2pod.pl (at contrib/texi2pod.pl in gcc's repo) replaces @t{...} with the wrapped text as-is, which I think is an acceptable behavior. The fixed-width font distinction is not really important for a man page, where the text will be displayed with whatever font the user is using. Import the line that does that from gcc's version. I have verified that there is no other, unwanted change in man pages generated in binutils' and GDB's doc, with this patch applied. etc/ChangeLog: * texi2pod.pl: Handle @t{...} tags.
2020-01-15Use get_thread_regcache instead of get_current_regcache in post_create_inferiorSimon Marchi2-1/+7
In post_create_inferior, we get the current thread using the inferior_thread function and store it in `thr`. We then call get_current_regcache immediately after, which does: return get_thread_regcache (inferior_thread ()); This patch makes post_create_inferior use get_thread_regcache, passing `thr`, saving an unnecessary inferior_thread call. gdb/ChangeLog: * infcmd.c (post_create_inferior): Use get_thread_regcache instead of get_current_regcache.

2020-01-16tic4x disassembly static variablesAlan Modra2-31/+54
tic4x uses a number of static variables for tables that are generated depending on the current machine (tic4x vs. tic3x). However, it is possible to change the machine from one invocation of print_insn_tic4x to the next. This patch throws away the old state if that happens, and uses a relatively small known size array of register names rather than a malloc'd table. * tic4x-dis.c (tic4x_version): Make unsigned long. (optab, optab_special, registernames): New file scope vars. (tic4x_print_register): Set up registernames rather than malloc'd registertable. (tic4x_disassemble): Delete optable and optable_special.

Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor.
