* Rewrite tui_putsTom Tromey2020-09-272-12/+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.
* Use ISCNTRL in tui_copy_source_lineTom Tromey2020-09-272-3/+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.
* Use a curses pad for source and disassembly windowsTom Tromey2020-09-278-71/+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.

* gdb: Fix from_tty argument to gdb.execute in Python.Gareth Rees2020-09-264-4/+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.

* Import mklog.py from gcc repoSimon Marchi2020-09-252-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | dwz in DWARF5 mode might produce DW_UT_partial unit types, which are the same as DW_UT_compile unit types (but start with a DW_TAG_partial_unit) and it might produce DW_FORM_ref_addr to create a reference between units. Accept both constructs. binutils/ChangeLog: * dwarf.c (read_and_display_attr_value): Handle DW_FORM_ref_addr for dwarf_version 5 just as version 3 and 4 (only 2 is different). (process_debug_info): Allow DW_UT_partial.

* Handle 64bit breakpoints of WOW64 processes as SIGINTHannes Domani2020-09-247-7/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | When a WOW64 process triggers a breakpoint exception in 64bit code (which happens when a 64bit gdb calls DebugBreakProcess for a 32bit target), gdb ignores the breakpoint (because Wow64GetThreadContext can only report the pc of 32bit code, and there is not int3 at this location). But if these 64bit breakpoint exceptions are handled as SIGINT, gdb doesn't check for int3, and always stops the target. gdb/ChangeLog: 2020-09-23 Hannes Domani <ssbssa@yahoo.de> * nat/windows-nat.c (handle_exception): Handle 64bit breakpoints in WOW64 processes as SIGINT. * nat/windows-nat.h: Make wow64_process a shared variable. * windows-nat.c: Remove static wow64_process variable. gdbserver/ChangeLog: 2020-09-23 Hannes Domani <ssbssa@yahoo.de> * win32-low.cc: Remove local wow64_process variable. * win32-low.h: Remove local wow64_process variable.
