2020-09-27Rewrite tui_putsTom Tromey2-12/+68
This rewrites tui_puts. It now writes as many bytes as possible in a call to waddnstr, letting curses handle multi-byte sequences properly. Note that tui_puts_internal remains. It is needed to handle computing the start line of the readline prompt, which is difficult to do properly in the case where redisplaying can also cause the command window to scroll. This might be possible to implement by reverting to single "character" output, by using mbsrtowcs for its side effects to find character boundaries in the input. I have not attempted this. gdb/ChangeLog 2020-09-27 Tom Tromey <tom@tromey.com> PR tui/25342: * tui/tui-io.c (tui_puts): Rewrite. Move earlier.
2020-09-27Use ISCNTRL in tui_copy_source_lineTom Tromey2-3/+9
This changes tui_copy_source_line to use ISCNTRL. This lets it work more nicely with UTF-8 input. Note that this still won't work for stateful multi-byte encodings; for that much more work would be required. However, I think this patch does not make gdb any worse in this scenario. gdb/ChangeLog 2020-09-27 Tom Tromey <tom@tromey.com> PR tui/25342: * tui/tui-winsource.c (tui_copy_source_line): Use ISNCTRL.
2020-09-27Use a curses pad for source and disassembly windowsTom Tromey8-71/+140
This changes the TUI source and disassembly windows to use a curses pad for their text. This is an important step toward properly handling non-ASCII characters, because it makes it easy to scroll horizontally without needing gdb to also understand multi-byte character boundaries -- this can be wholly delegated to curses. Horizontal scrolling is probably also faster now, because no re-rendering is required. gdb/ChangeLog 2020-09-27 Tom Tromey <tom@tromey.com> * unittests/tui-selftests.c: Update. * tui/tui-winsource.h (struct tui_source_window_base) <extra_margin, show_line_number, refresh_pad>: New methods. <m_max_length, m_pad>: New members.

This removes a call to show_source_line from tui_source_window_base.

2020-09-27Use an inner window in tui_py_windowTom Tromey2-27/+42
This changes tui_py_window to create an inner curses window. This greatly simplifies tui_py_window::output, beacuse it no longer needs to be careful to avoid overwriting the window's border. This patch also makes it a bit easier for a later patch to rewrite tui_copy_source_line. gdb/ChangeLog 2020-09-27 Tom Tromey <tom@tromey.com> * python/py-tui.c (class tui_py_window) <refresh_window>: New method. <erase>: Update. <cursor_x, cursor_y>: Remove. <m_inner_window>: New member.

2020-09-26gdb: Fix from_tty argument to gdb.execute in Python.Gareth Rees4-4/+32
Prior to commit 56bcdbea2b, the from_tty keyword argument to the Python function gdb.execute controlled whether the command took input from the terminal. When from_tty=True, "starti" and similar commands prompted the user: (gdb) python gdb.execute("starti", from_tty=True) The program being debugged has been started already. Start it from the beginning? (y or n) y Starting program: /bin/true Program stopped. When from_tty=False, these commands did not prompt the user, and "yes" was assumed: (gdb) python gdb.execute("starti", from_tty=False) Program stopped. However, after commit 56bcdbea2b, the from_tty keyword argument no longer had this effect. For example, as of commit 7ade7fba75: (gdb) python gdb.execute("starti", from_tty=True) The program being debugged has been started already. Start it from the beginning? (y or n) [answered Y; input not from terminal] Starting program: /bin/true Program stopped. Note the "[answered Y; input not from terminal]" in the output even though from_tty=True was requested. Looking at commit 56bcdbea2b, it seems that the behaviour of the from_tty argument was changed accidentally. The commit message said: Let gdb.execute handle multi-line commands This changes the Python API so that gdb.execute can now handle multi-line commands, like "commands" or "define". and there was no mention of changing the effect of the from_tty argument. It looks as though the code for setting the instream to nullptr was accidentally moved from execute_user_command() to execute_control_commands() along with the other scoped restores. Accordingly, the simplest way to fix this is to partially reverse commit 56bcdbea2b by moving the code for setting the instream to nullptr back to execute_user_command() where it was to begin with. Additionally, add a test case to reduce the risk of similar breakage in future. gdb/ChangeLog: PR python/26586 * cli/cli-script.c (execute_control_commands): don't set instream to nullptr here as this breaks the from_tty argument to gdb.execute in Python. (execute_user_command): set instream to nullptr here instead. gdb/testsuite/ChangeLog: PR python/26586 * gdb.python/python.exp: add test cases for the from_tty argument to gdb.execute.

The save of r2 in __glink_PLTresolve is the culprit. Remove it, unless we know we need it for --plt-localentry. --plt-localentry should not be used with power10 pc-relative code that makes tail calls.

2020-09-25Import mklog.py from gcc repoSimon Marchi2-0/+265
I've been using the mklog utility from the gcc repo for a while to generate skeleton of ChangeLog entries. It recently got a rewrite as a Python script. Unfortunately, to find the repository root, and eventually to find in which ChangeLog file each entry goes, the new script assumes it is located in the same git repository that it generates ChangeLog entries for. This means that if you make a change in the gcc source tree and run mklog.py from that same source tree, it works. But if you make changes in your ~/src/binutils-gdb tree and run ~/src/gcc/contrib/mklog.py, it won't work. IIRC, the old script required that you ran it with the project's root directory as the CWD. The simplest way to fix this is to import the script in binutils-gdb and use it from there. It's also nice because we can use it without having a clone of the gcc repo. I also thought of adding a "--root" switch to the script to override the project's base directory. However: 1) It is more work. 2) If the script still lives in the gcc repo, it's less convenient than having it in binutils-gdb. This patch imports contrib/mklog.py from the gcc repo, revision c560591408440f441b8b327f5b41f9328d20b67b. contrib/ChangeLog: * mklog.py: New file, imported from gcc.

2020-09-25Fix compilation of .c files as C++ when using ClangGary Benson2-2/+8
In commit 221db974e653659edb280787af1b3efdd1615083, this patch: 2020-06-24 Pedro Alves <palves@redhat.com> * lib/gdb.exp (gdb_compile): Pass "-x c++" explicitly when compiling C++ programs. attempted to fix problems with testcases that compile .c files with the C++ compiler. They pass the "c++" option to gdb_compile, resulting in the following error when using Clang: gdb compile failed, clang-10: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated] This fix did not work for gdb.base/infcall-nested-structs-c++.exp, however: the "-x c++" appeared in the compiler's commandline after the .c file, so the option was not enabled for that file. The previous files fixed all used build_executable_from_specs, which compiles and links in separate steps, using gdb_compile: the compile step passes $type=object to gdb_compile, while the link step passes $type=executable. gdb.base/infcall-nested-structs-c++.exp uses gdb_compile directly instead, and it passes $type=executable to compile and link all in one step. Pedro found that DejaGnu's default_target_compile adds the sources at the end when $type=object, but at the beginning when $type=executable: # This is obscure: we put SOURCES at the end when building an # object, because otherwise, in some situations, libtool will # become confused about the name of the actual source file. if {$type == "object"} { set opts "$add_flags $sources" } else { set opts "$sources $add_flags" } This commit moves the "-x c++" earlier in the compiler's commandline. Unfortunately this then broke the testcase that required the original fix, gdb.compile/compile-cplus.exp: the "-x c++" was being parsed for the linker pass, causing the compiler to attempt to parse the .o files as C++. This commit makes passing "-x c++" conditional on the source being a .c file. gdb/testsuite/ChangeLog: * lib/gdb.exp (gdb_compile): Pass "-x c++" earlier, and only for .c files.

2020-09-24PR26656, power10 libstdc++.so segfault in __cxxabiv1::__cxa_throwAlan Modra2-185/+259
This adds missing support for a power10 version of the __tls_get_addr call stub implementing DT_PPC64_OPT PPC64_OPT_TLS. Without this, power10 code using __tls_get_addr fails miserably at runtime unless the --no-tls-get-addr-optimize option is given. PR 26656 * elf64-ppc.c (plt_stub_size): Add "odd" param. Use it with size_power10_offset rather than calculating from start of stub. Add size for notoc tls_get_addr_opt stub. (plt_stub_pad): Add "odd" param, pass to plt_stub_size.

2020-09-24PR26655, Power10 libstdc++.so R_PPC64_NONE dynamic relocsAlan Modra5-15/+50
Some of the powerpc64 code editing functions are better run after dynamic symbols have stabilised in order to make proper decisions based on SYMBOL_REFERENCES_LOCAL. The dynamic symbols are processed early in bfd_elf_size_dynamic_sections, before the backend always_size_sections function is called. One function, ppc64_elf_tls_setup must run before bfd_elf_size_dynamic_sections because it changes dynamic symbols. ppc64_elf_edit_opd and ppc64_elf_inline_plt can run early or late, I think. ppc64_elf_tls_optimize and ppc64_elf_edit_toc are better run later. So this patch arranges to call some edit functions later via always_size_sections. PR 26655 bfd/ * elf64-ppc.c (ppc64_elf_func_desc_adjust): Rename to.. (ppc64_elf_edit): Call params->edit. (ppc64_elf_tls_setup): Don't call _bfd_elf_tls_setup. Return a bfd_boolean. * elf64-ppc.h (struct ppc64_elf_params): Add "edit".

2020-09-23Handle bit offset and bit size in base typesTom Tromey9-7/+406
PR symtab/25470 points out that the Zig programming language allows integers of various bit sizes (including zero), not just sizes that are a multiple of 8. This is supported in DWARF by applying both a byte size and a DW_AT_bit_size. This patch adds support for this feature to integer and boolean types. Other base types are not handled -- for floating-point types, this didn't seem to make sense, and for character types I didn't see much need. (These can be added later if desired.) I've also added support for DW_AT_data_bit_offset at the same time. I don't know whether the Zig compiler requires this, but it was described in the same section in the DWARF standard and was easy to add. A new test case is supplied, using the DWARF assembler. gdb/ChangeLog 2020-09-23 Tom Tromey <tom@tromey.com> PR symtab/25470: * value.c (unpack_long, pack_long, pack_unsigned_long): Handle bit offset and bit size. * printcmd.c (print_scalar_formatted): Handle zero-length integer.
