Tom de Vries	e4ad960a57	[gdb/symtab] Remove superfluous end-of-sequence marker While working on PR26935 I noticed that when running test-case gdb.base/morestack.exp with target board unix/-m32/-fPIE/-pie and ld linker, I get this linetable fragment for morestack.S using readelf -wL: ... CU: ../../../../libgcc/config/i386/morestack.S: Line number Starting address View Stmt 109 0xc9c x ... 838 0xe03 x - 0xe04 636 0 x 637 0x3 x - 0x4 ... but with "maint info line-table" I get: ...

So, apparently the entries with addresses 0x0 and 0x3 are filtered out because the addresses are out of range, but the same doesn't happen with the end-of-seq terminator.

Simon Marchi	3ec3145c5d	gdb: introduce scoped debug prints I spent a lot of time reading infrun debug logs recently, and I think they could be made much more readable by being indented, to clearly see what operation is done as part of what other operation. In the current format, there are no visual cues to tell where things start and end, it's just a big flat list. It's also difficult to understand what caused a given operation (e.g. a call to resume_1) to be done. To help with this, I propose to add the new scoped_debug_start_end structure, along with a bunch of macros to make it convenient to use. The idea of scoped_debug_start_end is simply to print a start and end message at construction and destruction. It also increments/decrements a depth counter in order to make debug statements printed during this range use some indentation. Some care is taken to handle the fact that debug can be turned on or off in the middle of such a range. For example, a "set debug foo 1" command in a breakpoint command, or a superior GDB manually changing the debug_foo variable. Two macros are added in gdbsupport/common-debug.h, which are helpers to define module-specific macros: - scoped_debug_start_end: takes a message that is printed both at construction / destruction, with "start: " and "end: " prefixes. - scoped_debug_enter_exit: prints hard-coded "enter" and "exit" messages, to denote the entry and exit of a function. I added some examples in the infrun module to give an idea of how it can be used and what the result looks like. The macros are in capital letters (INFRUN_SCOPED_DEBUG_START_END and INFRUN_SCOPED_DEBUG_ENTER_EXIT) to mimic the existing SCOPE_EXIT, but that can be changed if you prefer something else. Here's an excerpt of the debug statements printed when doing "continue", where a displaced step is started: [infrun] proceed: enter [infrun] proceed: addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT [infrun] global_thread_step_over_chain_enqueue: enqueueing thread Thread 0x7ffff75a5640 (LWP 2289301) in global step over chain [infrun] start_step_over: enter [infrun] start_step_over: stealing global queue of threads to step, length = 1 [infrun] start_step_over: resuming [Thread 0x7ffff75a5640 (LWP 2289301)] for step-over [infrun] resume_1: step=1, signal=GDB_SIGNAL_0, trap_expected=1, current thread [Thread 0x7ffff75a5640 (LWP 2289301)] at 0x5555555551bd [displaced] displaced_step_prepare_throw: displaced-stepping Thread 0x7ffff75a5640 (LWP 2289301) now [displaced] prepare: selected buffer at 0x5555555550c2 [displaced] prepare: saved 0x5555555550c2: 1e fa 31 ed 49 89 d1 5e 48 89 e2 48 83 e4 f0 50 [displaced] amd64_displaced_step_copy_insn: copy 0x5555555551bd->0x5555555550c2: c7 45 fc 00 00 00 00 eb 13 8b 05 d4 2e 00 00 83 [displaced] displaced_step_prepare_throw: prepared successfully thread=Thread 0x7ffff75a5640 (LWP 2289301), original_pc=0x5555555551bd, displaced_pc=0x5555555550c2 [displaced] resume_1: run 0x5555555550c2: c7 45 fc 00 [infrun] infrun_async: enable=1 [infrun] prepare_to_wait: prepare_to_wait [infrun] start_step_over: [Thread 0x7ffff75a5640 (LWP 2289301)] was resumed.

[infrun] prepare_to_wait: prepare_to_wait [infrun] proceed: end: resuming threads, all-stop-on-top-of-non-stop [infrun] proceed: exit We can easily see where the call to `proceed` starts and end. We can also see why there are a bunch of resume_1 calls, it's because we are resuming threads, emulating all-stop on top of a non-stop target. We also see that debug statements nest well with other modules that have been migrated to use the "new" debug statement helpers (because they all use debug_prefixed_vprintf in the end. I think this is desirable, for example we could see the debug statements about reading the DWARF info of a library nested under the debug statements about loading that library. Of course, modules that haven't been migrated to use the "new" helpers will still print without indentations. This will be one good reason to migrate them. I think the runtime cost (when debug statements are disabled) of this is reasonable, given the improvement in readability. There is the cost of the conditionals (like standard debug statements), one more condition (if (m_must_decrement_print_depth)) and the cost of constructing a stack object, which means copying a fews pointers. Adding the print in fetch_inferior_event breaks some tests that use "set debug infrun", because it prints a debug statement after the prompt. I adapted these tests to cope with it, by using the "-prompt" switch of gdb_test_multiple to as if this debug statement is part of the expected prompt. It's unfortunate that we have to do this, but I think the debug print is useful, and I don't want a few tests to get in the way of adding good debug output. gdbsupport/ChangeLog: * common-debug.h (debug_print_depth): New.

Simon Marchi	e71daf80d3	gdb: use infrun_debug_printf in print_target_wait_results The code in print_target_wait_results uses a single call to debug_printf in order to make sure a single timestamp is emitted, despite printing multiple lines. The result is: 941502.043284 [infrun] target_wait (-1.0.0, status) = [infrun] 649832.649832.0 [process 649832], [infrun] status->kind = stopped, signal = GDB_SIGNAL_TRAP I find this decision a bit counter productive, because it messes up the alignment of the three lines. We don't care that three (slightly different) timestamps are printed. I suggest to change this function to use infrun_debug_printf, with this result: 941601.425771 [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) = 941601.425824 [infrun] print_target_wait_results: 651481.651481.0 [process 651481], 941601.425867 [infrun] print_target_wait_results: status->kind = stopped, signal = GDB_SIGNAL_TRAP Note that the current code only prints the waiton_ptid as a string between square brackets if pid != -1. I don't think this complexity is needed in a debug print. I made it so it's always printed, which I think results in a much simpler function. gdb/ChangeLog: * infrun.c (print_target_wait_results): Use infrun_debug_printf.

Simon Marchi	335709bc5a	gdb: make "set debug timestamp" work nice with new debug printouts New in v2: - implement by modifying vprintf_unfiltered rather than debug_prefixed_vprintf.

Each call gets its own timestamp and newline, curtesy of vprintf_unfiltered. My first idea was to add a "line_start" parameter to debug_vprintf, allowing the caller to say whether the print is the start of the line. A debug timestamp would only be printed if line_start was true. However, that was much more invasive than the simple fix implemented in this patch. My second idea was to make debug_prefixed_vprintf use string_printf and issue a single call to debug_printf. That would however prevent future use of styling in the debug messages. What is implemented in this patch is the same as is implemented in GDBserver: the timestamp-printing code in GDB tracks whether the last debug output ended with a newline. If so, it prints a timestamp on the next debug output. After the fix, it looks like this: $ ./gdb -q -nx --data-directory=data-directory -ex "set debug infrun" -ex "set debug timestamp" a.out Reading symbols from a.out...

Luis Machado	098caef485	Refactor struct trad_frame_saved_regs The following patch drops the overloading going on with the trad_frame_saved_reg struct and defines a new struct with a KIND enum and a union of different fields. The new struct looks like this: struct trad_frame_saved_reg { setters/getters ... private: trad_frame_saved_reg_kind m_kind; union { LONGEST value; int realreg; LONGEST addr; const gdb_byte value_bytes; } m_reg; }; And the enums look like this: / Describes the kind of encoding a stored register has. / enum class trad_frame_saved_reg_kind { / Register value is unknown. / UNKNOWN = 0, / Register value is a constant. / VALUE, / Register value is in another register. / REALREG, / Register value is at an address. / ADDR, / Register value is a sequence of bytes. / VALUE_BYTES }; The patch also adds setters/getters and updates all the users of the old struct. It is worth mentioning that due to the previous overloaded nature of the fields, some tdep files like to store negative offsets and indexes in the ADDR field, so I kept the ADDR as LONGEST instead of CORE_ADDR. Those cases may be better supported by a new enum entry. I have not addressed those cases in this patch to prevent unwanted breakage, given I have no way to test some of the targets. But it would be nice to clean those up eventually. The change to frame-unwind. is to constify the parameter being passed to the unwinding functions, given we now accept a "const gdb_byte " for value bytes.

Mike Frysinger	0ede24f2c4	sim: common: add align_{up,down} to match gdb We have ALIGN_{8,16,PAGE} and FLOOR_PAGE macros (where PAGE is defined as 4k) which were imported from the ppc sim. But no other sim utilizes these and hardcoding the sizes in the name is a bit limiting. Let's delete these and import the two general macros that gdb uses: align_up(addr, bytes) align_down(addr, bytes) This in turn allows us to cut over the Blackfin code immediately.	11 years ago
