2019-08-15Fix CU overrun in scan_unit_for_symbolsTom Tromey2-1/+6
A customer program had a DWARF CU that consisted of just a CU DIE, without any children. In this situation, scan_unit_for_symbols will try to read past the end of the current CU, and will take use the first bytes of the next CU as an abbrev, printing an error message. This patch fixes the bug by changing scan_unit_for_symbols to stop at the end of the CU rather than the end of the .debug_info section. bfd/ChangeLog 2019-08-15 Tom Tromey <tromey@adacore.com> * dwarf2.c (scan_unit_for_symbols): Check for end of CU, not end of section.

2019-08-14AArch64: Allow additional sizes in prologueAlan Hayward5-22/+139
When saving registers to the stack at the start of a function, not all state needs to be saved. For example, only the first 64bits of float registers need saving. However, a program may choose to store extra state if it wishes, there is nothing preventing it doing so. The aarch64_analyze_prologue will error if it detects extra state being stored. Relex this restriction. Tested via aarch64-prologue test. gdb/ChangeLog: * aarch64-tdep.c (aarch64_analyze_prologue): Allow any valid register sizes. gdb/testsuite/ChangeLog: * gdb.arch/aarch64-prologue.c: New test. * gdb.arch/aarch64-prologue.exp: New file.

2019-08-13Don't track the contents of the execution info windowTom Tromey3-70/+22
The curses library keeps track of the contents of each window, and can redraw the screen as needed. This means that in most cases is no need for the TUI windows to also keep track of their contents. This patch removes content tracking from the execution window, leaving that to curses. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_exec_info_window) <~tui_exec_info_window, maybe_allocate_content, get_content, m_content>: Remove.

2019-08-13Remove tui_clear_exec_info_contentTom Tromey3-18/+16
After the previous patch, all calls to tui_clear_exec_info_content come just after a call to tui_clear_source_content. Because these two windows are linked, I think it makes sense to have tui_clear_source_content simply do the work. So, this patch removes tui_clear_exec_info_content. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_clear_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_update_source_window_as_is) (tui_update_source_windows_with_addr, tui_erase_source_content): Update.

2019-08-13Remove tui_erase_exec_info_contentTom Tromey3-9/+11
One call to tui_erase_exec_info_content can be removed. This call is not needed because the function in question then immediately sets the execution info window contents. Once this is done, tui_clear_exec_info_content is just a wrapper for the only call to tui_erase_exec_info_content, so tui_erase_exec_info_content can be renamed and the wrapper function removed. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_erase_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_source_window_base::refresh_all): Don't call tui_erase_exec_info_content.

2019-08-13Two simplifications in tui-layout.cTom Tromey2-119/+116
This patch simplifies some code in tui-layout.c. In show_layout, all the layout settings can be handled by a single switch statement. In show_source_disasm_command and show_source_or_disasm_and_command, there is no need to check the current layout, as the caller has already done so. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (show_layout): Unify all layout cases into a single switch.

2019-08-13Simplify tui_make_all_invisibleTom Tromey4-16/+18
This simplifies the implementation of tui_make_all_invisible. Also, because show_data is only called by show_layout, this hoists the call to tui_make_all_invisible and removes the call from show_data. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (make_all_visible): Remove.

2019-08-12Fix gdb's selftest.exp after readline importPatrick Palka2-3/+26
After the sync there is one testsuite regression, the test "signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously, the readline 6.2 SIGINT handler would temporarily reinstall the underlying application's SIGINT handler and immediately re-raise SIGINT so that the orginal handler gets invoked. But now (since readline 6.3) its SIGINT handler does not re-raise SIGINT or directly invoke the original handler; it now sets a flag marking that SIGINT was raised, and waits until readline explicitly has control to call the application's SIGINT handler. Anyway, because SIGINT is no longer re-raised from within readline's SIGINT handler, doing "signal SIGINT" with a stopped inferior gdb process will no longer resume and then immediately stop the process (since there is no 2nd SIGINT to immediately catch). Instead, the inferior gdb process will now just print "Quit" and continue to run. So with this commit, this particular test case is adjusted to reflect this change in behavior (we now have to send a 2nd SIGINT manually to stop it). gdb/testsuite/ChangeLog 2019-08-12 Patrick Palka <patrick@parcs.ath.cx> * gdb.gdb/selftest.exp (test_with_self): Update test to now expect the GDB inferior to no longer immediately stop after being resumed with "signal SIGINT".

2019-08-12Add generic and ARM specific support for half-precision IEEE 754 floating ↵Barnaby Wilks20-8/+324
point numbers to the assembler. Half precision floating point numbers will be encoded using the IEEE 754 half precision floating point format - 16 bits in total, 1 for sign, 5 for exponent and 10 bits of mantissa. This patch implements the float16 directive for both the IEEE 754 format and the Arm alternative format for the Arm backend. The syntax of the directive is: .float16 <0-n decimal numbers> e.g. .float16 12.0 .float16 0.23, 433.1, 0.06 The Arm alternative format is almost identical to the IEEE 754 format, except that it doesn't encode for NaNs or Infinity (instead an exponent of 0x1F represents a normalized number in the range 65536 to 131008). The alternative format is documented in the reference manual: https://static.docs.arm.com/ddi0487/db/DDI0487D_b_armv8_arm.pdf?_ga=2.72318806.49764181.1561632697-999473562.1560847439 Which format is used is controlled by the .float16_format <format> directive, where if <format> = ieee, then use the IEEE 754 half-precision format else if <format> = alternative, then use the Arm alternative format Or the format can be set on the command line via the -mfp16-format option that has a similar syntax. -mfp16-format=<ieee|alternative>. This also fixes the format and it cannot be changed by any directives. Once the format has been set (either by the command line option or a directive) it cannot be changed, and any attempts to change it (i.e. with the float16_format directive) will result in a warning and the line being ignored. For ELF targets the appropriate EABI attribute will be written out at the end of assembling if the format has been explicitly specified. If no format has been explicitly specified then no EABI attributes will be written. If the format is not explicitly specified then any float16 directives are encoding using the IEEE 754-2008 format by default until the format is fixed or changed with the float16_format directive. gas * config/tc-arm.c (enum fp_16bit_format): Add enum to represent the 2 float16 encodings.
